Experimental Study on Mix Ratio Design and Road Performance of Medium and Small Deformation Seamless Expansion Joints of Bridges

Expansion joints are a weak and fragile part of bridge superstructure. The damage or failure of the expansion joint will lead to the decline of bridge durability and endanger the bridge structure and traffic safety. To improve the service life and performance of bridge expansion joints, the ideal method is to use seamless expansion joints. In this study, starting from the commonly used asphalt mixture gradation of seamless expansion joint, and taking into account the actual situation of bridge expansion joint structure and environment in China, the gradation and asphalt-aggregate ratio are preliminarily designed. Through a Marshall test, the corresponding asphalt mixture is evaluated and analyzed according to the stability, flow value, and void ratio, and the optimal gradation and asphalt-aggregate ratio are determined. Finally, the asphalt mixture is prepared with the mixture ratio design, and the test results of an immersion Marshall test, fatigue performance test, and full-scale test verify that the asphalt mixture meets the road performance requirements of seamless expansion joints. On the basis of the experimental data, the performance of large sample asphalt mixture is continuously tested, compared, and optimized. The results show that the asphalt mixture ratio designed is true and reliable, which can provide reference for the optimal design of seamless expansion joint filler.

Analysis of factors affecting water stability of foam warm mix asphalt mixture

water stability of warm mix asphalt mixture based on foamed asphalt is the key evaluation index affecting its road performance. The moisture content in the production process of foamed asphalt is unfavorable to the water stability of warm mix asphalt mixture. In order to improve its water stability, through immersion Marshall test and freeze-thaw splitting test, taking foaming effect, asphalt temperature, foaming water consumption and polymer fiber content as influencing factors, the control variable method is used to study and analyze the influence of factors on the water stability of warm mix asphalt mixture. The test results show that the foaming effect of asphalt, asphalt temperature, foaming water consumption and fiber content are the direct factors affecting the water stability of warm mix asphalt mixture. According to the importance analysis of random forest variables, foaming water consumption, foaming effect and asphalt temperature are the most important variables, while fiber content is the least. Taking the asphalt used in this paper as an example, it is suggested to improve the water stability of warm mix asphalt mixture with the combination of the best foaming effect, asphalt temperature 155 °C, foaming water consumption 2% and fiber content 0.3%.

Preparation of shape memory epoxy resin for asphalt mixtures and its influences on the main pavement performance

Thermally induced shape memory polymers (SMPs) are stimulated by a temperature change, and in response to that change, can be restored to their initial state by adjusting the mechanical parameters, which is known as shape memory property. Thermally induced SMPs may reduce the high-temperature rutting of asphalt mixtures. Herein, a suitable shape was produced by adding a shape memory epoxy resin (SMER) by into an asphalt mixture. Four different kinds of SMERs were prepared in this study, and a fibrous shape memory epoxy resin (F-SMER) was chosen for application in asphalt mixtures. The molecular structures, thermostability, and thermal properties of the F-SMER were measured by Fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The high-temperature performance, low-temperature crack resistance and water stability of the asphalt mixture were measured by a rutting test, bending test, immersion Marshall test and freeze–thaw splitting test. The results show that the thermostability of the F-SMER met the requirements for use in asphalt mixtures. The dynamic stability first increased and then decreased with increasing F-SMER proportion. The low-temperature performance of the asphalt mixture mixed with F-SMER met all specification requirements. The incorporation of F-SMER was also advantageous to the water stability of the asphalt mixtures.

The degree of influence of pavement environment on the deterioration of pavement performance of basalt fiber asphalt concrete is as follows: ultraviolet aging > high and low temperature alternating cycle > freeze-thaw cycle > salt freeze-thaw cycle.

Road performance of liquid nitrile-butadiene rubber modified unsaturated polyester resin concrete

Unsaturated polyester resin concrete (UPC) is currently gaining attention in many fields due to its functional compressive capacity and corrosion resistance. However, the toughness of UPC is poor due to the weak resistance to the deformation of the cured unsaturated polyester resin (UP). In this paper, the UP was modified with liquid nitrile-butadiene rubber (LNBR) and further used to make concrete. At the same time, two different initiators were used to cure the UPC and LNBR modified UPC. To study the mechanism and road performance of LNBR modified UPC performance, optical microscopy test, Marshall test, water immersion Marshall test, rutting test, freeze–thaw split test, and infrared spectroscopy experiments were carried out. Test results showed that LNBR could effectively improve the low-temperature toughness of UPC. Although LNBR slightly reduced the Marshall stability and rutting resistance of UPC, it hardly changed the water stability of the UPC. LNBR could crosslink with UP to form a joint body, and the amount of initiator may have a more significant impact on the performance of the UPC and LNBR modified UPC.

Quantitative Analysis Investigation of the Water Stability of Asphalt Mixtures with Crushed Gravel Based on the Theory of Surface Free Energy

To quantitatively analyze and study the water stability of crushed gravel asphalt mixture by using surface energy theory, the surface energy parameters of crushed gravel samples at 20℃ are tested by using the gas sorption method, and the surface energy parameters of four anti-stripping agent asphalts with different dosages (0%, 0.2%, 0.4%, 0.6%) at 20℃ are tested by using the Wilhelmy plate method. Then, the binding energy of crushed gravel and anti-stripping agent asphalts with different dosages and the surface energy evaluation index of water stability are calculated. On this basis, quantitative analysis and sequencing of water stability of crushed gravel asphalt mixture were carried out. The microscopic mechanism of the anti-stripping agent's improvement on adhesion between crushed gravel and asphalt was analyzed from the angle of surface energy. Marshall test (immersion Marshall test, vacuum saturation Marshall test, freeze-thaw splitting test) with anti-stripping agent contents of 0%, 0.2%, 0.4%, and 0.6% was conducted through strict control of crushed gravel material, gradation, and oil-stone ratio. Results show that (1) the surface energy parameters of crushed gravel are dominated by polar alkali component; (2) the addition of anti-stripping agent will reduce the surface energy of asphalt, thus increasing the wettability of asphalt to aggregate; (3) the improvement of the adhesion between crushed gravel and asphalt by adding anti-stripping agent is mainly reflected in two aspects: reducing the cohesive energy of asphalt itself to increase its wettability to aggregate and increasing the surface energy acid component of asphalt to increase its adhesion binding energy to aggregate; and (4) the order of microscopic surface energy evaluation index of water stability of crushed gravel asphalt mixture is the same as that of macroscopic performance test index, thus demonstrating the accuracy of the surface energy system for quantitative analysis of the water stability of the crushed gravel asphalt mixture.

Laboratory Study on the Performance of Asphalt Mixes Modified with a Novel Composite of Diatomite Powder and Lignin Fiber

The performance and the fundamental weaknesses of asphalt mix under environmental temperature and water effects have made researchers try to modify the asphalt mix properties by using the proper additives. For this reason, this paper aims to improve the anti-cracking performance and water stability of asphalt pavement by adding a novel composite of diatomite and lignin fiber in asphalt mixes. Four types of asphalt mixes, including control asphalt mix (CAM), diatomite modified asphalt mix (DMAM), lignin fiber modified asphalt mix (LFMAM), and diatomite-lignin fiber composite modified asphalt mix (DLFMAM) were prepared in the laboratory. Low-temperature bending test, Marshall Immersion test, and freeze-thaw splitting test were employed to evaluate the performance of the asphalt mixes. Results reveal that the use of the lignin fiber in reinforced asphalt mixes combined with diatomite led to an enhancement in the asphalt pavement performance more than the other three types of mixes. Diatomite has an important influence on the water damage resistance of asphalt mix more than lignin fiber. On the other hand, diatomite has a small effect on the anti-cracking performance; meanwhile, lignin fiber showed a significant improvement in the cracking resistance of asphalt mixes. DLFMAM has the best traveling performances among all asphalt mixes. Thus, this work provides a good reference for the design of composite asphalt mixes.

Effect of Dry–Wet and Freeze–Thaw Repeated Cycles on Water Resistance of Steel Slag Asphalt Mixture

As an attractive substitute of natural aggregate for asphalt mixture, steel slag raises many concerns on the water resistance of steel slag asphalt mixture in frozen and wet areas, due to the special interaction between steel slag and asphalt. This study aims to investigate the deterioration process of water resistance for asphalt mixture with different steel slag contents in dry–wet and freeze–thaw cycles environments. The Marshall immersion test and indirect tensile test were conducted, and the residual stability and tensile strength ratio (TSR) were measured to characterize the water resistance of the steel slag asphalt mixture. Furthermore, dry–wet and freeze–thaw repeated cycling conditions were designed to simulate the effect of actual environments on the long-term water resistance of asphalt pavement. Finally, the microstructures of the aggregate–asphalt interface area were observed, and the enhancement mechanism of the steel slag replacement in asphalt mixture was revealed. Results show that steel slag asphalt mixture exhibits significant resistance to water damage. With the increase in dry–wet or freeze–thaw repeated cycles, the water resistance of steel slag asphalt mixture rapidly deteriorates first and then tends to be stable, and there is a limit state of water damage. In dry–wet repeated cycles condition, the asphalt mixture with 50% steel slag content has a better water resistance, while the asphalt mixture with 100% steel slag content has a better water resistance under freeze–thaw repeated cycles condition. The interface phase structure of steel slag asphalt mixture is stable and dense, where the asphalt mortar evenly and tightly wraps the steel slag and forms a certain penetration depth. The enhancement mechanism of steel slag with asphalt mainly includes the physical anchoring effect and the chemical adhesion effect.

Laboratory research on road performances of unsaturated polyester concrete at medium-high temperature

Unsaturated polyester resin (UP) and aggregate can synthesize unsaturated polyester resin concrete (UPC) with high performance, which was often used to fill materials and wear layers. However, the UP contained in UPC was usually high, resulting in high engineering cost. At the same time, there is less researches on the direct use of UPC as a paving material. In this paper, the Marshall mix design procedure was used to design UPC, and the road performance of UPC at medium-high temperature were studied. The aging test, Marshall test, the water immersion Marshall test, and the rutting test were performed to observe the road indicators of the UPC. At the same time, the uniaxial creep test and the indirect tensile test at different temperatures were carried out to observe the performances change of UPC with temperature. Results showed that UPC had a better water-resistance ability than that of asphalt mixture (AC) under the coupling effects of high temperature and water. Besides, the dynamic stability (DS) values of UPC were higher than that of asphalt mixture. However, UPC had a lower residual strain rate and creep rate relative to the asphalt mixture. The bonding effect of the UPC was better than that of the asphalt mixture at high temperature from the indirect tensile test results. High-temperature aging had a visible deteriorating impact on the high-temperature performance of asphalt mixture. As the UP is a thermosetting resin, UPC had excellent high-temperature durability. With the aging time increasing, the mechanical properties of UPC gradually decreased, but its mechanical properties were still superior to asphalt mixtures under the same aging conditions.

Characteristics of waste tire rubber (WTR) and amorphous poly alpha olefin (APAO) compound modified porous asphalt mixtures

Waste tire rubber (WTR) and amorphous poly alpha olefin (APAO) compound modified asphalt had good high temperature and anti-aging properties, which were needed for porous asphalt (PA) mixtures. The purpose of this paper was to evaluate the feasibility of WTR/APAO (WTR+4%APAO and WTR+6%APAO) compound modified asphalt for PA mixture and compare it with 70 # base asphalt, WTR modified asphalt and Tafpack Super (TPS) modified asphalt for PA mixture. First, the Cantabro test and draindown test were carried out to determine optimum asphalt contents (OAC) for all asphalt mixtures. Then, a series of performances tests were conducted on the asphalt mixtures at their OAC, including Marshall test, rutting test, low temperature three-point bending test, immersion Marshall test, Cantabro test before and after aging, pendulum friction test, to assess the high and low temperature performance, water resistance, aging resistance and skid resistance, respectively. The test results showed that as compared to WTR PA mixture, WTR/APAO PA mixture had smaller Cantabro abrasion loss, draindown and OACs, better high temperature performance, water, aging and skid resistances, and worse low temperature performance. WTR+6%APAO PA mixture had the best high temperature performance and water resistance of all PA mixtures. The aging resistances of WTR+6%APAO PA mixture was second only to that of TPS PA mixture. The skid resistance of WTR+6%APAO PA mixture was second only to that of 70# PA mixture. It was feasible to using WTR/APAO modified asphalt as the binder of PA mixture in non cold area according to Chinese standard JTG F40-2004 and WTR+6%APAO PA mixture performed better than WTR+4%APAO PA mixture. Future research was recommended on the influence of compaction condition and asphalt content on the WTR/APAO PA mixture properties such as fatigue resistance and permeability.

Experimental study of high modulus asphalt mixture containing reclaimed asphalt pavement

This paper examines performance of high modulus asphalt mixture containing reclaimed asphalt pavement (RAP). Low penetration grade asphalt binder #30 was used to produce high modulus asphalt mixture containing RAP. Marshall mix design method was used to prepare specimen and EME (Enrobé à Module Élevé) method was incorporated. To address the variance of RAP gradation and poor bonding between stiff virgin binder and aged binder, a modified regeneration method was proposed in this study and was compared with traditional method. Performance of the mixture was examined with lab tests including Marshall stability and flow test, dynamic modulus test, bending test, Marshall immersion test and modified Lottman test. The results indicated that modified method produced more compacted, more stable mixture than traditional method, while low-temperature performance is still below standard. Specimens with different RAP content were prepared and tested to evaluate the effect of RAP content. It was found that 40% RAP produced optimal mixture in terms of dynamic modulus values and moisture damage susceptibility, while low-temperature performance is insensitive to RAP content. Scanning Electron Microscope (SEM) test was conducted to evaluate bonding between binder and aggregate from the micro structural perspective. The results support that modified method improves the bonding between virgin binder and RAP as well as virgin aggregate.

Characteristics Comparison of Refinery Asphalt, Rubberized Asphalt, and Buton Asphalt in Stone Matrix Asphalt Pavement with Marshall and Cantabro Method

The most common flexible pavement used in Indonesia were asphalt concrete and hot rolled sheet, with the most frequently problem caused by the extremely high traffic load. Because of that, an alternative type of pavement needed. Stone matrix asphalt (SMA) is a mixture with gap gradation which contains a large portion of coarse aggregates and forms a skeleton that efficiently spreads the load due to passing vehicles. SMA mixture consists of three types, that is thin SMA, fine SMA and rough SMA. The utilization of several types of asphalt also can be an alternative. In this research will be made a comparison about SMA mixture with buton asphalt, rubberized asphalt, and refinery asphalt based on Marshall properties, followed with Marshall immersion and cantabro test based on the optimum asphalt content. Overall based on the test result, the combination of SMA mixture with rubberized asphalt was the best. It had the highest stability with the lowest optimum asphalt content. While for the marshall immersion test, the stability of all sample after 24 hours soaked in waterbath were decreased. Also based on cantabro test result, the best index of retained strength value were for SMA mixture with rubberized asphalt.

Effects of silane coupling agent modified coal waste powder on performance of asphalt mortar and asphalt mixture

In view of the disadvantage that coal waste powder(CWP) can reduce the crack resistance of asphalt mortar at low temperature, silane coupling agent KH-550 was used to modify coal waste powder. The surface characteristics and modification mechanism of silane coupling agent modified coal waste powder were characterized by using Scanning Electronic Microscopy (SEM). Five kinds of silane coupling agent modified coal waste powder asphalt mortar with content 0%, 0.5%, 1.0%, 1.5%, 2.0% and limestone(LS) powder asphalt mortar were prepared under different filler-asphalt ratios, respectively. The effects and mechanism of silane coupling agent modified coal waste powder on the pavement performance of asphalt mortar and asphalt mixture was studied by the dynamic shear rheological test(DSR), low temperature bending beam rheological test (BBR), Brookfield viscosity test, adhesion test, Fourier Transform Infrared Spectroscopy (FTIR), rutting test, bending test at low temperature, immersion Marshall test and freeze-thaw split test. The results showed that the optimal proportion of KH-550 is 1.5% of CWP mass and CWP modified by silane coupling agent can greatly enhance high temperature performance, low temperature performance and adhesion of the asphalt mortar. Furthermore, CWP modified by silane coupling agent can significantly improve rutting resistance, low temperature crack resistance and water damage resistance of asphalt mixture.

The statistical hypothesis test results also confirmed that WTR/APAO modified asphalt has a significant effect on mechanical properties. Based on the results of various performance, the 15% WTR+4% APAO was the optimal content for asphalt mixture.

Analysis of Influencing Factors of Performance for Sandstone Asphalt Mixture

To analyze the performance for pavement and its influencing factors of sandstone asphalt mixture, eight kinds of asphalt mixture combination plans were designed to discuss the influences of various coarse aggregate, fine aggregate and different types of anti-stripping agents on road performance. The rutting test, beam bending test, immersion Marshall test and freeze-thaw splitting test were conducted on these samples.

Moreover, the high temperature and low temperature performance is significantly enhanced than that of pure limestone mixture; The water stability can be improved by adding slurred lime, cement and anti-strapping agent, but there is no significant difference between Marshall test and freeze-thaw splitting test. As for fine aggregate, there is no significant difference between white limestone and cyan limestone.

Preparation and Properties of an Active Cooling Antirutting Asphalt Mixture

To reduce the temperature of asphalt pavements in summer and improve their high‐temperature stability, tourmaline anion powder (TAP) was used as a modifier to prepare modified asphalt, which actively cools the pavement. The effects of different TAP contents on the high‐ and low‐temperature performance of modified asphalt and its pavement cooling performance were studied based on the dynamic shear rheometer, low‐temperature bending beam rheometer, and indoor rutting plate temperature difference tests; subsequently, the optimum TAP content was determined. Modified asphalt was used to prepare an active cooling antirutting asphalt mixture, and its pavement cooling performance was verified via outdoor lighting tests. High‐ and low‐temperature dynamic modulus and low‐temperature semicircular splitting tests were used to evaluate the high‐ and low‐temperature performance; further, freeze‐thaw splitting and immersion Marshall tests were performed to evaluate the water stability of the active cooling antirutting asphalt mixture. The results denote that TAP is useful for improving the rutting factor of asphalt. When the TAP content is 16% of the asphalt material, the maximum cooling value of the surface in laboratory tests becomes 5.9°C. When compared with an ordinary asphalt mixture, the dynamic stability of the active cooling antirutting asphalt mixture at medium and high temperatures increased by 18%–22%. The fracture energy can be increased by 12% at low temperatures. The maximum cooling value of the surfaces in outdoor tests is 7.2°C, and the water stability slightly decreases; however, it still satisfies the specification requirements.

Study on the Parameter Optimization and Strength Mechanism of Coal Gangue Emulsified Asphalt Mixture

Emulsified asphalt mixture has the characteristics of convenient construction and durable performance, but its poor early strength and demulsification seriously restrict the popularization and application of this material. At present, the coal gangue produced by coal‐fired power plants is generally discarded, resulting in serious environmental pollution. The combination of coal gangue and emulsified asphalt can explore an efficient utilization way for more and more coal gangue and also solve the curing problem of asphalt. In order to give full play to the advantages of existing materials and make rational use of resources, this paper studies the factors affecting the performance of coal gangue emulsified asphalt mixture based on orthogonal experimental design and optimizes its material composition parameters by considering the coupling effect of two factors. The water stability of coal gangue emulsified asphalt mixture is evaluated by the immersion Marshall test. Finally, the strength formation mechanism of coal gangue emulsified asphalt mixture is analyzed from the microscopic point of view. The results determined 7.5% as the optimum amount of emulsified asphalt in coal gangue emulsified asphalt mixture and recommended the best parameter combination of 7.5% emulsified asphalt, 6% coal gangue, and 5% water consumption. With the increase of coal gangue content, the water loss resistance of emulsified asphalt mixture increases gradually, and the water stability of emulsified asphalt mixture can be improved by adding coal gangue. According to the microscopic analysis, the strength of the mixture is formed by the joint action of emulsified asphalt and coal gangue, in which the hydration products of coal gangue and asphalt play the role of cementation and strength together. The ordinary emulsified asphalt mortar mainly contains CaCO3, which mainly plays the role of physical filling.

Performance Evaluation of Recycled Asphalt Mixtures Containing Construction and Demolition Waste Applicated as Pavement Base

Construction and demolition waste contain large amount of concrete and bricks. To identify its feasibility of applying in asphalt stabilized gravel mixtures as pavement base, this paper carried out researches on properties of recycled asphalt mixture (RAM) by laboratory testing, under different contents of recycled aggregates (RA) and proportions of bricks to concrete. First, the basic physical properties of each component of the RAM were determined. According to the actual screening passing rate, the Bailey method was used to design and verify the grading of RAM, and then initial asphalt content was estimated. The stability, flow value, voidage, and bulk density were obtained by Marshall Test, and the optimal asphalt‐aggregate ratios were determined under different RA contents and proportion of bricks to concrete. Subsequently, the uniaxial compression test, splitting tensile test, immersion Marshall test, freeze‐thaw splitting test, and Hamburg rutting test were performed to investigate mechanical properties, water stability, and high‐temperature stability of RAM. The results shows that as the content of RA increases from 0% to 100%, the corresponding compressive strength, resilient modulus, and splitting tensile strength all decrease; the same change trend is presented in the residual stability and freeze‐thaw splitting test strength ratio and rutting depth. According to the requirement of pavement base of high‐grade roads in China’s standards, the recommended RA content and proportion of bricks to concrete were proposed for the design RAM.
