Ni–Ti multicell interlacing Gyroid lattice structures with ultra-high hyperelastic response fabricated by laser powder bed fusion

Ni–Ti alloys based on triple-periodic minimal surface lattice metamaterials have great application potential. In this work, the triply periodic minimal surface (TPMS) lattice structures with the same volume fraction from a normal Gyroid lattice to an octuple interlacing Gyroid lattice were prepared by the laser powder bed fusion (LPBF) technique. The influence of the interlacing-cell number on manufacturability, uniaxial compression mechanical behaviors, and hyperelastic responses of Ni–Ti lattice structures are analysed by experiments. The stress distributions and fracture mechanism of multicell interlacing lattice structures are illustrated by the finite element method. The obtained results reveal that when the volume fraction is the same, the specific surface area of the lattice structure increases with increasing interlacing-cell number, and the curvature radius of the single-cell strut reduces, which leads to the decrease in the manufacturability of the lattice structure. Meanwhile, the diameter of the single cell strut decreases, and the stress it can bear decreases, which leads to a decline in the compressive mechanical property of the lattice structure. However, the number of struts increases with the increase of interlacing cells, which makes the stress distribution of the lattice structure more uniform. The cyclic compression results indicate that with increasing interlacing-cell number, the proportion of the hyperelastic recoverable strain increases, and the residual strain in the cyclic compression test decreases. For the lattice structure with a chiral arrangement of single cells, the manufacturability, compressive mechanical properties, and hyperelasticity are comparable to those with a normal arrangement. Notably, the Ni–Ti Gyroid TPMS lattice structures have superior hyperelasticity properties (98.87–99.46 % recoverable strain).

In-plane seismic behaviour of urm and confined masonry built from vertically perforated blocks and polyurethane glue

Masonry construction using vertically perforated clay blocks with large holes and polyurethane glue is a modern technology designed primarily for low thermal losses. This study aims to evaluate the in-plane seismic behaviour of masonry constructed using unreinforced masonry (URM) and confined masonry construction technology. The experimental methods consist of triplet tests on joints and cyclic shear compression tests on eight full-scale walls, six of which are URM and two of which are confined masonry. Tests on URM walls are performed at three different levels of compressive stress to analyse the effect of compressive stress on the seismic response. The effects of compressive stress on shear resistance and drift capacity are quantified and compared with results from a database. The performance of the tested walls is comparable to what is expected from modern URM walls. Two confined masonry walls were of the same dimensions as the URM walls and are evaluated at the highest compressive stress level used in tests of URM walls. The results indicate that confined masonry should be the preferred technology for seismic regions because of its higher strength, displacement capacity, ductility, and energy dissipation.

Ti30Zr10Hf10Ni35Cu15 high-entropy shape memory alloy with tunable transformation temperature and elastocaloric performance by heat treatment

This work investigates the influence of heat treatments on a pseudo-binary Ti30Zr10Hf10Ni35Cu15 high-entropy shape memory alloy. Heat treatments on the alloy resulted in the formation of second phases and thus were able to adjust its transformation temperatures. This phenomenon results from the formation of H-phase and (Zr,Hf)7Cu10 phase during low-temperature and high-temperature aging, respectively. The superelasticity of solution-treated, 500 °C-aged and 700 °C-aged samples was tested under compression, and all samples exhibited nearly 5 % recoverable strain and 15 °C elastocaloric cooling capacity. Further cyclic compression tests confirmed their stability, with up to 75 % of the initial cooling capacity retained after 5000 compression cycles. Due to its high yield strength, the Ti30Zr10Hf10Ni35Cu15 high-entropy shape memory alloy showed great superelasticity and elastocaloric performance at various testing temperatures. Furthermore, with heat treatments, the austenitic transformation finishing temperature (Af) of the alloy was tunable to between −10 °C (furnace-cooled) and 60 °C (700 °C-aged) with promising functional performance. These features expand the application range of TiZrHfNiCu high-entropy shape memory alloys as potential superelastic and elastocaloric materials.

High-quality 3D printing of ethylene vinyl acetate with direct pellet-based FDM for medical applications: Mechanical analysis, energy absorption and recovery evaluation

Ethylene Vinyl Acetate (EVA) is a biocompatible and non-toxic copolymer known for its applications in medicine, drug delivery systems, and energy absorption. This paper presents a novel method for 3D printing EVA using the Fused Deposition Modeling (FDM) technique. By directly utilizing pellet-form EVA material and employing pneumatic pressure for extrusion, we addressed the issue of filament buckling commonly encountered in traditional filament-based printing. A custom-made pellet printer enabled direct feeding of polymer pellets. The mechanical properties, microstructure of the printed EVA parts was analyzed to evaluate the suitability of the direct pellet printing technique for producing high-quality EVA components. The results showed acceptable printing quality and favorable mechanical properties (about 1000% elongation at break and 6.59 MPa tensile strength). Additionally, a cyclic compression test was conducted, subjecting specimens to various strains (30%,80% and 120%) and assessing their compressive and energy absorption properties undergoing significant deformations. Observations reveal a noticeable decline in the mechanical properties after the first compression cycle. The mechanical properties tend to stabilize and reach a steady state from the second cycle onwards until the sixth cycle. Furthermore, a compression cyclic test with various strain rates conducted, investigated the functional performance of the printed EVA components in engineering and biomedical applications, considering the impact of strain rate. Observations indicate that lower strain rates tend to enhance the material's ability to withstand deformation before yielding. This study contributes to expanding the potential of EVA in additive manufacturing, particularly in biomedical and energy absorption systems.

Experimental study on mechanical properties of Beishan granite in the mild temperature range

The response of mechanical property to temperature, especially in the mild temperature range, is important for the high-level waste (HLW) geological disposal engineering. To study the temperature effect on the deformation properties and the mobilization of strength of Beishan granite, the incremental cyclic loading-unloading compressive tests under various temperatures (T) and confining pressure (σ3) conditions (T = 25 °C, 60 °C and 90 °C, σ3 = 0 MPa, 5 MPa and 20 MPa) were carried out on Beishan granite. Results showed: (1) During the entire compression process, the cohesive strength is weakening while the frictional strength is strengthening. The CWFS model was developed considering the temperature effect. (2) For the peak strength, the cohesion decreased while the friction increased with increasing temperature in the range of 25 °C–90 °C. (3) The mechanism of cohesion weakening and friction strengthening with increasing temperature was discussed based on the micro-structure measurement. Clear thermal induced crack/pore closure was observed in granite after mild temperature treated, which contributes to friction strengthening and stiffness improvement. (4) The strength response to temperature (cohesion weakening and friction strengthening with increasing temperature) will result in ‘transition pressure (10.1 MPa for crack damage stress, and 14.9 MPa for peak strength)’ for Beishan granite under mild temperature that the surrounding granite would be strengthened by the elevated temperature under higher confining pressure. The transition pressure is important for high-level waste geological disposal engineering in repository layout design optimization.

Implant-Supported Fixed Partial Dentures with Posterior Cantilevers: In Vitro Study of Mechanical Behavior.

Rehabilitation with dental implants is not always possible due to the lack of bone quality or quantity, in many cases due to bone atrophy or the morbidity of regenerative treatments. We find ourselves in situations of performing dental prostheses with cantilevers in order to rehabilitate our patients, thus simplifying the treatment. The aim of this study was to analyze the mechanical behavior of four types of fixed partial dentures with posterior cantilevers on two dental implants (convergent collar and transmucosal internal connection) through an in vitro study (compressive loading and cyclic loading). This study comprised four groups (n = 76): in Group 1, the prosthesis was screwed directly to the implant platform (DS; n = 19); in Group 2, the prosthesis was screwed to the telescopic interface on the implant head (INS; n = 19); in Group 3, the prosthesis was cemented to the telescopic abutment (INC; n = 19); and in Group 4, the prosthesis was cemented to the abutment (DC; n = 19). The sets were subjected to a cyclic loading test (80 N load for 240,000 cycles) and compressive loading test (100 KN load at a displacement rate of 0.5 mm/min), applying the load until failure occurred to any of the components at the abutment-prosthesis-implant interface. Subsequently, an optical microscopy analysis was performed to obtain more data on what had occurred in each group. Results: Group 1 (direct screw-retained prosthesis, DS) obtained the highest mean strength value of 663.5 ± 196.0 N. The other three groups were very homogeneous: 428.4 ± 63.1 N for Group 2 (INS), 486.7 ± 67.8 N for Group 3 (INC), and 458.9 ± 38.9 N for Group 4 (DC). The mean strength was significantly dependent on the type of connection (p < 0.001), and this difference was similar for all of the test conditions (cyclic and compressive loading) (p = 0.689). Implant-borne prostheses with convergent collars and transmucosal internal connections with posterior cantilevers screwed directly to the implant connection are a good solution in cases where implant placement cannot avoid extensions.

Lightweight biodegradable porous poly(propylene carbonate)/carbon nanostructures nano/microcellular structures with enhanced foamability, good electromagnetic interference shielding, and low permanent strain

Poly(propylene carbonate)/carbon nanostructures (PPC/CNS) composite foam with excellent comprehensive performance was successfully fabricated using supercritical carbon dioxide (Sc-CO2) as the physical foaming agent. Transmission electron microscope analysis revealed that the CNS was uniformly dispersed within the PPC matrix. This effective dispersion of CNS, coupled with enhanced melt strength, consequently facilitated the foamability of PPC/CNS composites. Remarkably, at a CNS loading of 3 wt%, the cell size of PPC/CNS composite foam reduced from micron to nanoscale dimensions, resulting in a cell density surpassing 1013 cell/cm3. Furthermore, the prepared PPC/CNS composite and its foams exhibited promising potential for applications in electromagnetic interference (EMI) shielding and sensor. For instance, by incorporating 3.0 wt% CNS, the EMI SSE reached 84.70 dB cm3/g after foaming, which exhibited favorable EMI shielding characteristics. Moreover, the composite foam exhibited excellent resilience and stability, led to a reduction of residual strain to less than 11 % after 10 cyclic compression tests.

Suitability of warm mix asphalt (WMA) technologies based on performance and energy consumption

Studying the effects of material variability on the performance of warm mix asphalt (WMA) is important to understand the benefits of reduced production temperatures. This study compares the performance of five different WMA mixtures prepared with two varying base binders and two different aggregate sources. The rutting, fatigue, and moisture sensitivity of asphalt mixtures were evaluated using cyclic compression test, indirect tensile cracking test, and modified Lottman test, respectively. Additionally, a theoretical analysis was used to compare the energy consumption during the production process. The results indicated that the performance of WMA is a function of the type of the base binder, aggregate source, and the type of WMA technology. Nonetheless, all the WMA mixtures contributed to higher energy savings in comparison to hot mix asphalt (HMA). Based on the ranking framework used in this study, the use of Rediset is recommended to achieve adequate performance and lower energy consumption.

Properties of three collagen scaffolds in comparison with native connective tissue: an in-vitro study

PurposeTo evaluate collagen scaffolds (CS) in terms of their in vitro resorption behavior, surface structure, swelling behavior, and mechanical properties in physiologically simulated environments, compared with porcine native connective tissue.Materials and methodsThree test materials—one porcine collagen matrix (p-CM), two acellular dermal matrices (porcine = p-ADM, allogenic = a-ADM)—and porcine native connective tissue (p-CTG) as a control material were examined for resorption in four solutions using a high-precision scale. The solutions were artificial saliva (AS) and simulated body fluid (SBF), both with and without collagenase (0.5 U/ml at 37 °C). In addition, the surface structures of CS were analyzed using a scanning electron microscope (SEM) before and after exposure to AS or SBF. The swelling behavior of CS was evaluated by measuring volume change and liquid absorption capacity in phosphate-buffered saline (PBS). Finally, the mechanical properties of CS and p-CTG were investigated using cyclic compression testing in PBS.ResultsSolutions containing collagenase demonstrated high resorption rates with significant differences (p < 0.04) between the tested materials after 4 h, 8 h and 24 h, ranging from 54.1 to 100% after 24 h. SEM images revealed cross-linked collagen structures in all untreated specimens. Unlike a-ADM, the scaffolds of p-CM and p-ADM displayed a flake-like structure. The swelling ratio and fluid absorption capacity per area ranged from 13.4 to 25.5% among the test materials and showed following pattern: p-CM > a-ADM > p-ADM. P-CM exhibited higher elastic properties than p-ADM, whereas a-ADM, like p-CTG, were barely compressible and lost structural integrity under increasing pressure.Conclusions and clinical implicationsCollagen scaffolds vary significantly in their physical properties, such as resorption and swelling behavior and elastic properties, depending on their microstructure and composition. When clinically applied, these differences should be taken into consideration to achieve the desired outcomes.Graphical

Designing Biomimetic Conductive Gelatin-Chitosan-Carbon Black Nanocomposite Hydrogels for Tissue Engineering.

Conductive nanocomposites play a significant role in tissue engineering by providing a platform to support cell growth, tissue regeneration, and electrical stimulation. In the present study, a set of electroconductive nanocomposite hydrogels based on gelatin (G), chitosan (CH), and conductive carbon black (CB) was synthesized with the aim of developing novel biomaterials for tissue regeneration application. The incorporation of conductive carbon black (10, 15 and 20 wt.%) significantly improved electrical conductivity and enhanced mechanical properties with the increased CB content. We employed an oversimplified unidirectional freezing technique to impart anisotropic morphology with interconnected porous architecture. An investigation into whether any anisotropic morphology affects the mechanical properties of hydrogel was conducted by performing compression and cyclic compression tests in each direction parallel and perpendicular to macroporous channels. Interestingly, the nanocomposite with 10% CB produced both anisotropic morphology and mechanical properties, whereas anisotropic pore morphology diminished at higher CB concentrations (15 and 20%), imparting a denser texture. Collectively, the nanocomposite hydrogels showed great structural stability as well as good mechanical stability and reversibility. Under repeated compressive cyclic at 50% deformation, the nanocomposite hydrogels showed preconditioning, characteristic hysteresis, nonlinear elasticity, and toughness. Overall, the collective mechanical behavior resembled the mechanics of soft tissues. The electrical impedance associated with the hydrogels was studied in terms of the magnitude and phase angle in dry and wet conditions. The electrical properties of the nanocomposite hydrogels conducted in wet conditions, which is more physiologically relevant, showed a decreasing magnitude with increased CB concentrations, with a resistive-like behavior in the range 1 kHz-1 MHz and a capacitive-like behavior for frequencies <1 kHz and >1 MHz. Overall, the impedance of the nanocomposite hydrogels decreased with increased CB concentrations. Together, these nanocomposite hydrogels are compositionally, morphologically, mechanically, and electrically similar to native ECMs of many tissues. These gelatin-chitosan-carbon black nanocomposite hydrogels show great promise for use as conducting substrates for the growth of electro-responsive cells in tissue engineering.

A new method of seismic strengthening stone masonry with CRM coatings on one side

The paper presents the results of a research study aimed at assessing the effectiveness of composite-reinforced mortar (CRM) for the seismic strengthening of existing stone masonry walls. The experimental research focused on the strengthening performance of a coating applied only on one side of the masonry wall. Such an application is interesting because it does not require the temporary relocation of residents. The historic two-wythe stone masonry used in the research represents Adriatic’s coastal and surrounding regions. The coating was made of hydraulic lime mortar reinforced with a glass fibre–reinforced polymer mesh attached to the wall using two types of anchors. In-plane cyclic shear compression tests and cyclic out-of-plane tests were conducted, and the performances of the coating on one and both sides were compared. The results showed that the coating on one side was effective, improving all aspects of the seismic response, which was successfully simulated using existing design models.

Fatigue mechanisms of a closed cell elastomeric foam: A mechanical and microstructural study using ex situ X-ray microtomography

The degradation of mechanical properties of closed-cell elastomeric foams in fatigue and its link with the cellular structure is still poorly understood. To clarify this, we performed interrupted and continuous cyclic compression tests on EVA closed-cell foams used in running shoes. The 3D cellular structures of tested samples was analyzed before, during and after fatigue tests using X-ray microtomography and digital volume correlation. Interrupting the cycling allows the observation of the cell flattening along the compression axis with both plastic bending and an increase of tears/holes of cell walls. These two fatigue-induced defects are suspected to play a strong contribution on the fatigue properties of the foam at the sample scale and may explain the partial recovery of the initial mechanical property of foams while restarting cycling.

Experimental and numerical study on the fatigue behaviour of the shot-earth 772

The present research work is devoted to the mechanical, fracture and fatigue experimental characterization of the shot-earth 772, with a particular attention to its fatigue behaviour. To such an aim, an extensive experimental program has been carried out, consisting of: (i) flexural and compression tests, (ii) three-point bending fracture tests, and (iii) bending and compression cyclic tests. Moreover, a FE numerical model is employed to simulate both the above bending and compression cyclic tests, after the input data validation performed by simulating the above fracture tests. The numerical fatigue lifetimes are compared with the corresponding experimental ones for both pulsating bending and compression, highlighting the model accuracy. Finally, the contours of both the damage parameter and the reduced Young modulus are plotted showing the evolution of fatigue damage.

Additively manufactured aluminium nested composite hybrid rocket fuel grains with breathable blades

ABSTRACT Hybrid rocket engines suffer from the restricted mechanical properties and low regression rates of current polymeric fuel grains. We propose a three-dimensional printed aluminium (Al) nested composite fuel grain with millimetre-scale lattice pores (referred to as Al-L). In this study, breathable Al blades with micrometer-scale interconnected pores (Al-B) and blades combining millimetre-scale and micrometer-scale pores (Al-B&L) are designed. The formation mechanisms, characteristics, and effects of the breathable blades are analysed in simulations, micro-computed tomography, and cyclic compression tests. The mechanical properties of the composite fuel grains are investigated numerically and in compression tests. Al-B has the highest Young’s modulus at more than 15 times that of a paraffin-based fuel grain and Al-B&L has the highest yield stress at 4 times that of the paraffin-based fuel grain. Referring to combustion properties, the regression rates of the Al-B and Al-B&L grains are respectively 63.3% and 58.2% greater than the regression rate of the paraffin-based fuel grain.

Magnetic field enhancing preferred orientation of nickel-cobalt plated carbon fibers in cement paste, with relevance to compression self-sensing

The arrangement of carbon fibers in the cement matrix affects the stability and sensitivity of the composite. This study investigated the effects of bath pH and electroless plating time on the magnetic metallization (nickel coating, cobalt coating, and nickel-cobalt alloy coating) on carbon fibers and successfully prepared the CFRCs in which the metal-plated carbon fibers could be oriented by magnetic fields. The results showed that a pH of 10 and a plating time of 6 min were favorable for reaction kinetics, with the thickness gain, conductivity, and saturation magnetization of metal coatings all being the largest. The compressive strength of the prepared composites was increased by 26.5% by adding nickel-cobalt coated carbon fibers, which is attributed to the alignment of fibers refining pore structure. The resistivity of CFRCs with metal-plated carbon fibers is one order lower in magnitude than that with uncoated carbon fiber, due to that the alignment of fibers increases the conduction connectivity by decreasing the distance of fiber-fiber and the “quantum tunneling”. The cyclic compressive loading tests showed that the resistance changed reversibly with strain, such that the degree of reversibility is higher for CFRCs with pre-magnetic treatment than those without the treatment. The piezoresistivity (strain sensitivity) of CFRCs was stronger with magnetic field-induced orientation treatment, showing that the strain sensitivity increased by 114% after pre-magnetic treatment for CFRCs containing nickel-cobalt coating. This is attributed to that the well-aligned metal-plated carbon fibers form more conduction paths along the alignment direction, such that the resistivity along this direction is more sensitive to the compressive strain parallel to this direction.

Soft polyurethane foam reinforced by expanded polystyrene particles: Compression performance, strain rate, and cyclic compression response

AbstractThe incorporation of particles with soft polyurethane (PU) foam aims to mechanically strengthen the PU foam as PU foam falls short of the mechanical expectation of academia and industries. In this study, the expanded polystyrene (EPS) particles are added to soft polyurethane foam, and composite foam with higher mechanical properties is successfully prepared by one‐step foaming process. The results show that under optimal conditions that is, EPS particle size of 0.5 mm and content of 2.5 wt% (EPS‐0.5‐2.5%), the synthesized foam has the smallest bubble pore diameter of 80 μm and has a stress of 0.284 MPa at 75% strain, which is much higher than that of blank polyurethane foam. As a result of a rise in the quantity of EPS particles, the composite PU foam shows a lower dependency on the strain rate. After the multiple cyclic compression test, PU foam exhibits a descending trend on the stress in the deformation plateau region. Besides, the low‐velocity impact test results indicate that the peak contact force of EPS‐0.5‐2.5% is lower than that of the control group by 632 N.

Energy Storage and Release of Class I and Class II Rocks

As underground excavations become deeper, violent rock failures associated with the sudden release of elastic energy become more prevalent, threatening the safety of workers and construction equipment. It is important to figure out the energy-related failure mechanisms of rocks. However, the energy evolution across the complete deformation of different types of rocks and the effect of high confinement on energy storage and release are not well understood in the literature. In this study, a series of cyclic triaxial compression tests were conducted for Class I and Class II rocks to investigate the confinement-dependent characteristics of energy evolution. The results showed that three types of energy evolution were identified as the rock behavior changed from brittle to ductile. The energy storage limit was linearly enhanced by confinement. The nonlinear increase in dissipated energy at peak stress with increasing confinement was suggested to indicate the start of the brittle–ductile transition. The post-peak fracturing process was characterized using the ratio of the local withdrawn elastic energy and fracture energy, and a novel energy-based index was proposed to quantify the failure intensity of the rock. This paper presents a complete investigation of the energy conversion characteristics of the rock, which may shed light on the failure mechanisms of violent rock failures in underground projects.

Fracture and energy evolution of rock specimens with a circular hole under multilevel cyclic loading

Underground structures gradually face increasing multilevel cyclic loading as construction progresses. In this paper, the fracture and energy evolution of rock specimens with a circular hole under multilevel cyclic loading were investigated using an experimental-theoretical approach. A series of multilevel cyclic loading tests were conducted on two types of rock (sandstone and granite) using the MTS 815 rock mechanics test system. Digital image correlation (DIC) and acoustic emission (AE) techniques were employed to monitor the fracture behavior of the rock with deformation and acoustic emission data recorded respectively. The total energy density, elastic energy density, and dissipated energy density of specimens are obtained by theoretical calculation. The results indicate that, despite the similarity in cracking sequence and fracture evolution of rock specimens with a circular hole between multilevel cyclic loading and uniaxial compression tests, there are differences in the AE activity under these two loading conditions. Additionally, the cracks around the hole under multilevel cyclic loading display a distinct “open-close-reopen” behavior. The energy density of rock specimens with a circular hole grows nonlinearly with stress. The elastic and dissipative energy density exhibits a linear relationship with the total energy density before rock failure. The fitting value of the elastic and dissipative energy density can be regarded as the energy storage coefficient and the energy dissipation coefficient, which could be further used to quantify the energy storage and dissipation capacities of rock. Under multilevel cyclic loading, the propagation of remote fractures and their coalescence with the shear fractures is the primary resource of AE energy, with only a few supplies given by micro-fissure closure and primary fractures. The dissipation energy in the rock structure can be described by the growth of AE energy. The findings indicate that there are distinct stages of energy release during the fracture evolution of cracks around the circular hole. These stages can be predicted by changes in AE energy or macroscopic energy, revealing the evolution stages of cracks and the modes of failure.

Carbon-Fiber- and Nanodiamond-Reinforced PLA Hierarchical 3D-Printed Core Sandwich Structures

The aim of the present paper is to investigate the mechanical behavior of FFF 3D-printed specimens of polylactic acid (PLA), PLA reinforced with nanodiamonds (PLA/uDiamond) and PLA reinforced with carbon fibers (PLA/CF) under various experimental tests such as compressive and cyclic compressive tests, nanoindentation tests, as well as scanning electron microscopy tests (SEM). Furthermore, the current work aims to design and fabricate hierarchical honeycombs of the zeroth, first and second order using materials under investigation, and perform examination tests of their dynamic behavior. The mechanical behavior of hierarchical sandwich structures was determined by conducting experimental bending tests along with finite element analysis (FEA) simulations. The results reveal that the incorporation of nanodiamonds into the PLA matrix enhanced the elastic modulus, strength and hardness of the 3D-printed specimens. In addition, the second order of the PLA/uD hierarchical sandwich structure presented increased strength, elastic and flexural modulus in comparison with the zeroth and first hierarchies. Regarding the dynamic behavior, the second order of the PLA/uD honeycomb structure revealed the biggest increase in stiffness as compared to PLA nanocomposite filaments.

Assessment of Waste Glass Incorporation in Asphalt Concrete for Surface Layer Construction.

The growing need to preserve natural resources and minimize landfill waste has led to an increased consideration of incorporating waste materials in road construction and maintenance. This study focuses specifically on utilizing waste glass as part of the aggregates in hot asphalt, particularly in Asphalt Concrete (AC) for surface layers, known as "Glassphalt". Glass, due to its poor adhesion to bitumen, presents challenges when used in asphalt mixtures. Two types of waste glass, monolithic and tempered, were incorporated at two distinct contents, 10% and 15%, into the AC. Several properties such as stiffness, resistance to permanent deformation (evaluated through cyclic compression tests), indirect tensile strength, and the indirect tensile strength ratio (ITSR) were assessed for all Glassphalt mixtures, as well as the conventional mixture. Additionally, the Solar Reflectance Index (SRI) was measured to evaluate the reflectivity of the resulting Glassphalts. The findings indicate that the incorporation of both types of waste glass resulted in reduced stiffness and resistance to permanent deformation. Regarding water sensitivity (ITSR), the Glassphalts containing 15% waste glass, regardless of the glass type, exhibited ITSR values below the accepted threshold of 80%. The addition of waste glass did not yield significant changes in SRI measurements.
