Evaluation of Flexible Pavement Friction Coefficients: A Case Study of East-West Highway Near Mahendranagar City, Nepal

Friction is a crucial factor in highway engineering, as it affects the traction between a vehicle's wheels and the road surface. This traction significantly influences the movement, speed, and efficiency of vehicles on highways. The coefficient of friction depends on various factors, such as pavement materials, traffic volume, road age, temperature, and weather conditions. The Skid Resistance Test Method is adopted for the study, which involves using a Portable Skid Resistance Tester to measure the British Pendulum Number (BPN) and then calculating the coefficient of friction by dividing the BPN by 10. An evaluation of a 5 km stretch of the East-West highway near Mahendranagar Bazaar revealed a longitudinal coefficient of friction of 0.354 and a lateral coefficient of friction of 0.184 under both dry and wet conditions. These findings were relevant for design speeds ranging from 60 to 80 km/h and considered an Annual Average Daily Traffic (AADT) of 10,321 Passenger Car Units (PCU) during the year 2023/2024. The assessment also indicated a variance of 0.19% and a poor International Roughness Index (IRI) value of 2.05. These aggregates had specific gravities ranging from 2.6 to 2.67 and were sized at 13.2 mm. The application rate for the aggregates ranged from 12 to 15 kg per square meter. It is important to note that a higher coefficient of friction leads to reduced vehicle efficiency. Thus, it is crucial to carefully consider the coefficient of friction values and detailed specifications to ensure traffic safety and road integrity.

Effects of aggregate shape on the macrotexture and performance of chip seal: a laboratory study

Chip seal is an efficient maintenance strategy for bituminous pavements, with aggregate shape significantly impacting its embedment and performance, but there is limited quantification of its effects. Using the Aggregate Image Measurement System II (AIMS-II) for shape classification, this study investigated the influence of aggregate shape on chip seal's macrotexture and performance through a series of tests, including 3D laser scanning test, aggregate coverage test, skid resistance test, and sweep test, employing response surface methodology (RSM) for quantification. Results indicated that an abundance of flat aggregates deteriorates surface quality by increasing roughness and altering texture spacing, recommending their proportion be kept under 10%. Conversely, elongated aggregates enhance performance by enriching texture depth and sharpening surface peaks. Spearman rank correlation analysis identified the arithmetic mean peak curvature (Spc ) and the root mean square height (Sq ) as reliable measures for evaluating skid resistance and aggregate retention of chip seals, respectively.

Low-speed skid resistance performance evaluation of airport runway pavements

ABSTRACT When skid resistance is found inadequate on an airport runway pavement, both high-speed and low-speed skid resistance characteristics of the pavement will have to be examined to determine the actual cause of the problem. Unfortunately, the widely used low-speed skid resistance measuring device, namely British Pendulum Tester (BPT), is not suitable for testing grooved pavements which are a common form of runway pavement construction. To solve the limitations of BPT, a Walking Friction Tester (WFT) was developed to test the low-speed skid resistance performance of airport runway pavements. Laboratory skid resistance tests using BPT and WFT were conducted on asphalt and concrete specimens, five of which were textured with standard square grooves and trapezoidal grooves. It was found that WFT produced more consistent measurements than BPT with smaller coefficient of variation values. Further tests were performed to examine the variability of WFT test results with respect to walking speed and water film thickness respectively. It was found that WFT test results were not affected by changes in walking speeds of operators and water film thickness. Therefore, it can be concluded that WFT is a better method for low-speed skid resistance evaluation of runway pavement.

Electric arc furnace slag in substitution of quartz for surface treatment of concrete paving slabs

Electric Arc Furnace (EAF) slag, a by-product of the steelmaking industry, also serves as a high-quality aggregate material for structural concrete production. In this research, its use is proposed as a Dry-Shake Hardener (DSH), in substitution of quartz, in concrete paving top coatings. Three concrete paving slab kinds were produced using EAF: one without fibers, another with metallic fibers; and the third with synthetic fibers. Half of each slab was coated with a classical cement-quartz mix and the other half with a novel cement-slag mix. After four years of outdoor aging at the city of Burgos, Spain, the slabs were visually inspected and no significant differences were found between the two coated materials. Impact, skid, and abrasion resistance tests were carried out and showed similar results for both types of coating courses. The result of both the short and long-term water absorption test results indicated, firstly, no short-term water absorption in both cases and, secondly, lower long-term water absorption in the quartz-cement mix. Finally, observation of the oil stain resistance tests on the top coatings led to the conclusion that the cleaning ability is very good. Analyzing all the results, it may be concluded that a new application for EAF slag have been found, it is a suitable material for use as a DSH for coating concrete paving slabs.

Assessing the Durability and Acoustic Performance of a Novel Two-Layer Pavement System

In the quest for more sustainable pavement solutions, this study demonstrates the successful strengthening of a unique noise-reducing two-layer road surface. While existing noise-reducing pavements reveal high acoustic efficiency, they lack mechanical strength, and earlier research efforts addressed the optimization of the individual components of this system, and a comprehensive perspective on its integrated performance remained elusive. Therefore, this research bridges this knowledge gap through an in-depth laboratory evaluation, in which the requirements for the realization of a full-scale demonstrator were defined, followed by a comprehensive performance assessment in terms of acoustic and mechanical strength. The post-construction assessment reveals the system’s multifaceted strengths, considering noise reduction, resilience under heavy traffic, pavement deflections, and skid resistance, assessed by CPX measurements, accelerated pavement tests using the MLS 30, skid resistance tests employing the pendulum test, as well as the slow-moving longitudinal friction test (MicroGriptester) and falling weight deflectometer (FWD) measurements. Although the optimized system implies lower noise-reduction potential, it exhibits great strength compared to previous noise-reducing pavements. In general, the system offers viable noise mitigation solutions for urban highways, particularly in settings where traditional noise abatement measures are constrained by space. The insights from this study serve as a valuable reference for the development and evaluation of innovative road engineering materials and technologies.

The Effect of Superplasticizer (SP) on the Workability and Skid Resistance of Geopolymer Concrete (GPC) Containing High Calcium Precursor (HCP)

A superplasticizer (SP) is one of the admixtures that may be used to improve the workability of concrete. However, its effects on geopolymer concrete (GPC) have yet to be well known or published, especially regarding its skid resistance and workability performance. This research aims to study the impact of the superplasticizer on the skid resistance and workability of geopolymer concrete containing high calcium precursor (HCP) in different proportions of SP, which are 0, 0.5, 1.0, 1.5 and 2.0 % by the weight of the HCP. Seven mix designs were produced: 1 conventional concrete mix, 5 geopolymers concrete mix, and 1 bituminous cold-mix asphalt mix. Slump flow and skid resistance tests were performed in this study. A skid resistance test is achieved using a British Pendulum Tester (BPT) on a 220 mm x 220 mm x 50 mm rectangle. This study found that the effect of SP on skid resistance is insignificant. However, the skid resistance of all GPC mix designs is higher than CC and asphalt mix. The workable flow of geopolymer concrete containing HCP and 0 - 2 % SP was 118-123 mm. However, less than 2 % of SP is given an insignificant difference. The optimum mix design of GPC is mix design GPC with an added 2 % SP (M6) that gives a high workability compared to other GPC mix designs and good skid resistance of 95 BPN. This study also found that workability correlates with skid resistance. The higher the spreading width value, the smaller the skid resistance value. In other words, the higher the flowability value, the less rough the sample surface. Hypothetically, the higher the percentage of SP, the higher the workability and the lower the skid resistance.

Anti-Icing Properties of a Polyurethane Superhydrophobic Coating on Asphalt Pavement

Snow and ice accumulation on asphalt pavement can increase the risk of traffic issues. The traditional method of removing snow and ice manually or mechanically from the road surface is time-consuming and labor-intensive. Another common method of spraying salt pollutes the surrounding environment. To overcome these issues, the objective of this study is to study a polyurethane superhydrophobic coating on asphalt pavement and characterize its anti-icing and road properties. A polyurethane superhydrophobic coating (PSC) using polyurethane and carbon nanotube particles (CNTPs) was developed in the lab. The contact angle and roll angle tests, surface roughness test, water droplet icing test, differential scanning calorimetry (DSC) test, ice adhesion test, pavement skid resistance test, water permeability test, and load wheel rolling test were conducted. The results show that the static contact angle and the rolling angle of the water droplet on the PSC surface are 161.176° and 6.6°, which satisfy the requirements to be superhydrophobic. The icing time of the water droplet on the asphalt mixture coated with PSC (AMC) is twice that of the surface of the ordinary asphalt mixture (OAM). In the differential scanning calorimetry test, the PSC released heat slower than polyurethane and asphalt binder during the cooling process. The ice adhesion strength of AMC is 82.78% smaller than that of the OAM. This means the PSC has great anti-icing and deicing properties. In addition, the pendulum value on the AMC surface is 45.7, satisfying the pavement skid resistance requirement. The results of the water seepage test show that the AMC is impermeable to water, thus reducing the risk of water damage to the pavement. Finally, the contact angle of the AMC after the indoor load wheel rolling is still greater than 150°, which proves that the PSC has good wear resistance. In summary, the PSC has good anti-icing properties and road performance.

Characteristics of Oil Palm Fruit Ash as Binder in Asphaltic Concrete

In order to reduce energy and natural resource consumption during road construction, the sustainability concept needs to be seriously addressed. Oil Palm Fruit Ash (OPFA) is one of the by-products of palm oil production that are typically disposed of in landfills as a result of the growing number of plantations in Malaysia, particularly in Sarawak. Due to the fact that OPFA is known as biomass with pozzolanic qualities (siliceous material), this study was carried out to examine the applicability of OPFA with varying concentrations (0% - 40%) by weight as a modifier in bitumen grade 60/70. Based on the results of the laboratory testing, it was discovered that the modified bitumen provided greater resistance to rutting, temperature, and skid resistance on the bituminous mixture (AC20) compared to the control sample. The 40% OPFA modified samples had the greatest resilient modulus test value, measuring 10992 MPa at 25 °C and 2936 MPa at 40 °C, respectively. In addition, the combination containing 40% OPFA produced the lowest deformation value in the dynamic creep test, which was only 0.20mm, while producing 83.63 skid numbers in the skid resistance test. OPFA can be utilized as a binder modifier to improve the performance of bituminous mixture, which indirectly supports the sustainable development goals (SDGs) concept in road construction, as this study conclusively demonstrated.

Detection and quantitative evaluation of pumping distress on bridge deck pavement through field and laboratory experiments

Pumping distress refers to the phenomenon of dynamic water entering a pavement, soaking the cement concrete layer to form slurry, and being pumped out of the pavement void under the action of traffic loading. Pumping distress is frequently reported in high temperature and rainy regions, such as Sichuan province in China. Various factors contribute to pumping distress on bridge decks, but most of these factors have merely been subjected to qualitative assessment. The aim of the study is to conduct a comprehensive quantitative analysis through three years of field investigations and laboratory experiments. The field investigations include ground penetrating radar (GPR), pavement permeability tests, skid resistance tests, and drainage facilities surveys. The quantitative analysis of the field and laboratory inspections revealed that the formation reason, deterioration rate, and damage degree of pumping distress were different between the truck and emergency lanes. The occurrence of pumping distresses was significantly related to the uneven construction of the bridge deck leveling layer, compaction segregation, and poor drainage. Additionally, the influence of pavement thickness uniformity on pumping distress was evaluated by incorporating GPR techniques. Failure in the waterproof adhesion layer resulted in the barrier between the cement concrete deck and the asphalt mixture breaking, which allowed alkaline sources to move and transfer to the pavement layer easily. The outcomes of this study can help bridge authorities and construction contractors choose appropriate design and construction measures to prevent pumping distress.

Investigation of the Antifreezing, Skid Resistance, and Waterproof Performances of an Acrylic and Polytetrafluoroethylene Coating for Asphalt Pavement

Freezing on asphalt roads affects driving safety. Spraying salt on roadways pollutes the environment. Mechanical deicing requires significant human and financial resources. This paper proposes a new approach to realize autonomous anti-icing of asphalt pavement, an acrylic/polytetrafluoroethylene coating (APC). The contact angle of a water droplet on the APC surface is 155.392°. Moreover, the freezing time of water droplets on the APC-coated asphalt mixture is 1.5 times longer than that of the uncoated asphalt mixture. Moreover, the skid resistance test results show that APC can increase the road friction coefficient, which is 1.2 times that of ordinary pavement. The water permeability test results confirm that APC can prevent water from penetrating into the road surface. In summary, APC improves the anti-icing performance of asphalt pavements and exhibits excellent anti-slip and waterproof properties.

GlasSphalt: A Borosilicate Based Sustainable Engineering Material for Asphalt Pavements

Large quantities of waste glass generated around the world are a source of environmental pollution and burden on landfill capacities. This glass can be brought in use by incorporating it in asphalt pavements as a replacement for aggregate particles. This research aims at evaluation of various structural, functional and durability parameters of asphalt containing waste borosilicate glass (BSG). Optimum binder content and volumetric characters were accessed using Marshall mix design method, wheel tracking test was used to evaluate the rutting resistance, and four-point beam fatigue test was used to measure the resistance against fatigue cracking. Deformation characteristics were studied using dynamic modulus test, and British pendulum test and aggregate polishing value test were used to study the skid resistance. Finally, moisture damage was evaluated using rolling bottle test. The results revealed that increasing BSG content reduces the optimum binder content requirements of final mixes. Maximum stability, maximum dynamic modulus, and rut resistance were observed at 10% dosage of BSG. Beam fatigue test results showed that BSG negatively affects the fatigue resistance of asphalt. However, this negative effect was insignificant for 5% dosage and slightly significant for 10% dosage, beyond which, considerable reduction in fatigue life was observed. Moisture damage studies showed that BSG had less affinity to adhere to bitumen, particularly when using dosage greater than 10% by weight. On one hand, skid resistance test showed that with the increasing quantity of BSG, skid resistance increased.

Experimental study on the high-speed frictional behavior between the tire and asphalt pavement

Driving speed, pavement type, surface characteristics, intermediate media, and tire properties are the key factors influencing the frictional behavior between tire and pavement. Although there are many kinds of equipment for friction coefficient tests based on the rubber-pavement contact mechanism, there is still a lack of equipment that can simulate the skid resistance behavior of high-speed vehicles based on real tire in the laboratory. Therefore, High-speed Friction Testing (HSFT) equipment was developed based on real tire loading, which well solves the deficiency of the current test methods. Based on this test platform, multi-factor coupling skid resistance tests were carried out on the asphalt concrete (AC-10/13/16) and the Open-Graded Friction Coarse (OGFC-10/13/16) samples. Statistical comparison and nonlinear fitting analysis were conducted on the results under various loading conditions The results show that driving speed, water film thickness, and tire load are all negatively correlated with skid resistance, and their influence extent can be ranked as water film thickness > tire load > driving speed. The established μHSFT skid resistance model based on multi-factor coupling shows high reliability, which can be used as the basis for pavement construction and is an important reference for future unmanned driving technology.

Evaluating the Influence of Carbon Fiber on the Mechanical Characteristics and Electrical Conductivity of Roller-Compacted Concrete Containing Waste Ceramic Aggregates Exposed to Freeze-Thaw Cycling

Traditional methods of removing snow and ice from pavements using chemicals are combined with mechanical removal that involves a lot of manpower, advanced machinery, chemicals that are harmful to the environment, and damage to pavements. Furthermore, annually, large quantities of ceramic materials become waste due to their fragile nature during processing, transport, and installation, and their accumulation in the nature has brought about environmental and health-related concerns. Therefore, the study aims to investigate the effect of using waste ceramic as a replacement for fine aggregate in roller compacted concrete (RCC) and the application of carbon fiber to improve the mechanical properties and electrical conductivity of RCC. To achieve this goal, several tests such as compressive strength, indirect tensile strength, electrical resistance, chloride ion penetration, specific gravity, and skid resistance tests were carried out on the fabricated samples before and after freeze-thaw cycling exposure. The experimental results illustrated that replacing waste ceramics with fine-grained aggregate increased the compressive strength and tensile strength of RCC. Furthermore, carbon fiber increased tensile strength but had no noticeable influence on compressive strength. Freeze-thaw conditioning led to a reduction in the compressive and tensile strength regardless of the aggregate type and carbon fiber utilization. In the samples containing waste ceramic aggregate, the electrical conductivity was reduced, and by adding carbon fiber, its electrical conductivity was increased. Exposure to freeze-thaw cycling resulted in an increase in electrical resistance and the passing charge. Waste ceramic incorporation created a similar mixture in terms of skid resistance, while in contrast, the carbon fiber slightly reduced the skid resistance. In addition, freeze-thaw conditioning resulted in an increase in the skid resistance. Besides, in this study, kernelized support vector regression (KSVR) and radial bias function (RBF) neural network models were proposed to estimate the indirect tensile strength (ITS) and compressive strength (CS) values. The results showed that both models have high performance in estimating these values, but RBF was a more efficient model.

Utilization of Bitumen Modified with Pet Bottles as an Alternative Binder for the Production of Paving Blocks

This study considers the utilization of bitumen modified with molten polyethylene terephthalate (PET) waste bottles as an alternative binder in paving blocks. PET waste was used at 2, 4, 6, 8, and 10% to modify bitumen in the production of paving blocks. Compressive strength test and skid resistance test were conducted on the paving block samples to evaluate their mechanical strength properties, while water absorption and the Cantabro abrasion tests were carried out to ascertain the durability of the paving block samples. The PET-modified bitumen paving blocks (PMBPB) have enhanced compressive strength and skid resistance compared to unmodified bitumen paving blocks. Also, a significant reduction in water absorption rate of up to 56% was achieved in PET-modified bitumen paving blocks (PMBPB) compared to the unmodified sample. The abrasion loss in the PMBCB samples was the least compared to that in normal cement paving blocks and unmodified bitumen paving blocks. The maximum compressive strength and least water absorption for the PET-modified bitumen concrete paving blocks were obtained at a 10% PET replacement level. It can be concluded that enhanced compressive strength and durability in cement paving blocks and unmodified bitumen paving blocks could be achieved with the use of PET modified bitumen in concrete paving block production, and this will also encourage PET waste recycling and contribute meaningfully to sustainability in concrete paving block production.

Bottom ash stabilized with cement and para rubber latex for road base applications

This study investigated the use of bottom ash mixed with Portland cement and para rubber latex as an alternative material for road work. Two bottom ash sizes viz., (1) passed number 4 sieve, and (2) passed a 3/8 in. sieve were tested. The bottom ash (BA) was mixed with 0%, 5%, 10%, 15%, and 20% ordinary Portland cement (OPC) and 0%, 2%, 4%, 6%, 8% and 10% para rubber latex (PRL). The unconfined compressive strength (UCS), skid resistance, and wet and dry durability tests were carried out. The results showed that the optimum mixes for light and heavy traffic were BA to OPC ratios of 95:5 and 93:7, respectively, at 6% PRL content. The skid resistance values showed that the BA–OPC–PRL mixtures had low slipping risk and achieved the suggested minimum value for safe road surface. The weight losses determined by the wet and dry durability test also satisfied the criteria set for road sub-base and base materials.

Architected cellular particles to mitigate asphalt stone loss

This paper aims to quantify stone loss mitigation due to the action of architected cellular particles that can absorb impact energy. The architected cellular particles presented in this paper are additives for asphalt that have been designed to absorb impact energy through an internal porous structure filled with a bitumen-compatible liquid that controls their strength. The experimental programme is divided into four phases: Cellular particle manufacturing and morphological analysis; optimisation of asphalt mixture performance by selecting the cellular particle content based on mass loss, rutting and skid resistance testing; study of mass loss with varying compaction energy and asphalt gradation and microstructural and energy absorption analysis. It was concluded that (i) the asphalt’s mass loss linearly decreased as the cellular particle content was increased, (ii) up to 1% of architected cellular particle content by total weight of the mixture reduced mass loss without producing adverse effects in the asphalt, (iii) architected cellular particles deformed during testing, absorbing the impact load energy.

Investigate the use of recycled polyvinyl chloride (PVC) particles in improving the mechanical properties of stone mastic asphalt (SMA)

Every year, millions of tons of industrial waste and household waste, including plastic waste, cause damage to the environment through landfilling, incineration, or dumping in open water. Polyvinyl chloride (PVC) is one of the most broadly used plastic materials in the modern world today, which can be reused in various industries by recycling waste. This matter can significantly help to improve environmental health. In this study, the impact of two kinds of recycled PVC (recycled water pipes and recycled candy wrappers) with three various percentages (2%, 3.5%, and 5% by weight of bitumen) on improving the mechanical properties of stone mastic asphalt (SMA) mixture has been investigated. For this purpose, in the present research, the Static creep test, Deformation strength test (Kim Test), Skid resistance test, indirect tensile strength (ITS) test, Semi-circular bending (SCB) fracture test, and conventional bitumen tests have been used. The conventional bitumen tests indicated that recycled PVC materials increased the softening point, viscosity, and specific gravity and reduced the penetration and the ductility of bitumen. Also, the results of mechanical tests illustrated that the addition of recycled water pipe particles and recycled candy wrapper particles improved the indirect tensile strength and increased the moisture resistance in stone mastic asphalt. However, increasing the percentage of these recycled materials to the asphalt mix had a negative effect on skid resistance. Regarding these recycled material's effects on rutting resistance, the Kim test depicted that raising the percentage of these recycled additives increases the rutting resistance of asphalt mixtures at high temperatures. Also, the static creep test revealed that the addition of these recycled PVCs reduces the accumulated permanent axial strain and increases the creep stiffness of stone mastic asphalt mixture. Moreover, based on the results of the fracture test, the addition of recycled PVC particles to the stone mastic asphalt mixture has a positive effect on the fracture energy at intermediate temperatures and intensity factor (Keff) at sub-zero temperature. Finally, in a general conclusion, it can be stated that recycled water pipe additive has a more notable influence on the mechanical properties of SMA mixture than recycled candy wrapper additive.

Experimental evaluation of multi-functional effects of fibers on mechanical and performance properties of Roller-compacted concrete pavements (RCCP)

The weak performance of asphalt pavements in different climatic conditions, quick decay of pavement, and lack of necessary durability have caused engineers and constructors to try to find Roller Compacted Concrete Pavement (RCCP) for use in various conditions and applications with outstanding properties such as higher durability, and lower maintenance costs. This paper aimed to investigate the mechanical and durability of RCCP by considering different types and amounts of fibers. Cylindrical specimens (with two diameters of 100 and 150 mm) and bending beams with four different fiber types (steel, Kortta Emboss, Kortta Twist, and Sinusoidal plastic) and different percentages were used and subjected to various tests. The compaction time (VB or Vebe) test on fresh concrete, the compressive strength, elastic modulus, the flexural strength, the Brazilian tensile strength, impact resistance, electrical resistance, and skid resistance tests on hardened concrete were conducted. A total of 17 fiber-reinforced concrete mixtures in addition to plain specimen were considered. The test results indicated that compressive, flexural, and tensile strengths of the specimen containing steel fibers were improved up to 27, 83, and 25%, respectively. Moreover, the flexural and tensile strengths of specimens containing Kortta Emboss fibers were improved up to 80 and 19%, respectively. The impact resistance of specimens containing steel and Kortta Emboss fibers were significantly improved up to 270 and 290%. Based on evaluating the results obtained from all tests, Kortta Emboss fiber was proposed as the best option among the studied fibers to improve the properties and functions of RCCP.

Pavement anti-icing coating based on a functional composite of NaCl microcapsules

Since NaCl can effectively inhibit ice adhesion onto pavement surface, this work prepared a pavement anti-icing coating (PAC) containing NaCl microcapsules, epoxy resin, and emery. The scanning electron microscopy–energy-dispersive spectrometry (SEM–EDS), X-ray diffraction (XRD), attenuated total reflection–Fourier transform infrared (ATR–FTIR), and thermogravimetric analysis (TGA) confirmed the successful preparation of the NaCl microcapsules. The continuous soaking and dissolution test and the skid resistance test were used to determine the optimal mass gain rate of the NaCl microcapsules and the optimal microcapsule and emery content of the coating to obtain a coating with long-lasting anti-icing and high skid resistance. Then, the skid resistance, the abrasion, and the anti-icing properties of the coating were analyzed. The optimal application amount of the coating was obtained, and the durability and anti-icing performance of the coating was examined. The results show that the coating has good abrasion resistance, and the release law of NaCl remains unchanged after the coating is worn. The coating reduces the adhesion strength of ice by 85.6% and 45.3% at a temperature of –3 and –13 °C respectively. The work provides an alternative to the existing active anti-icing of pavements.

Mechanical properties of roller-compacted concrete pavement containing recycled brick aggregates and silica fume

This study looks into the use of waste clay bricks, in roller-compacted concrete pavement (RCCP). To this end, waste were used in RCCP (at 0% to 100%) as a substitute for sand. Silica fume (SF) was also used to enhance the mechanical properties of the concrete. Mix designs containing 5% to 15% of SF were firstly prepared to determine the optimal amount of SF in the RCCP. Then, SF were used in bricks’ combination. Vebe, ultrasonic pulse velocity, compressive strength, water absorption, splitting tensile strength, abrasion resistance, and skid resistance tests were carried out on the samples. The results indicated that up to 25% substitution of brick waste for sand in RCCP did not cause any significant adverse effect. However, in amounts higher than 50%, the properties of concrete were affected. Thus, SF improved concrete properties and is capable of offsetting the negative effects of using bricks waste in RCCP.
