“…The use of brake pad waste as an aggregate did not significantly affect the mechanical properties and performance of the asphalt mixtures, including stability, rutting resistance, and moisture susceptibility [39,40]. Utilizing waste vegetable oil as a rejuvenator offers a promising approach to enhance the durability and sustainability of asphalt pavements, contributing to the circular economy and environmental conservation in addition waste vegetable oil improved the adhesion strength between the asphalt binder and aggregates, indicating enhanced bonding and cohesion [41]. Self-healing treatment improved the resistance to water infiltration and enhanced the overall durability of the steel deck asphalt pavement [42].…”

Highway infrastructures play an important part in local and international studies of emerging metropolitan cities because of their direct and indirect impact on urban expansion, environmental issues, and socioeconomic challenges.Transverse and longitudinal fractures, potholes, and subgrade deformation in flexible pavement result from the higher rate of vehicle addition on the roads to the space of road building. Due to an increase in the number of vehicles on the road, flexible pavements have developed cracks and deformations below the subgrade [1]. *Author for correspondence Different types of waste plastic bottles and optimizing the percentage of additive for improved performance of the asphalt [2].The effects of waste polymer modification on the performance and sustainability of asphalt mixtures. Their findings indicated improved resistance to fatigue cracking and reduced environmental impacts, particularly in terms of energy consumption and carbon emissions [3]. Incorporating disposable medical masks (DMM) enhanced the high and lowtemperature performance of the asphalt, leading to improved complex modulus, rotational viscosity, and tensile elongation. Furthermore, the addition of DMM fibers improved the moisture susceptibility, rutting resistance, and cracking resistance of the asphalt

This study addresses the need for effective rejuvenators in asphalt concrete mixtures containing Vacuum Tower Bottom (VB) binder, a by-product of petroleum refining. We investigated the use of a softening rejuvenator, comprising Carnauba (5.5%), Soybean oil (3%), water (81%), surfactant (1.5%), and additive (3%) from a Korean refining company, to mitigate the brittleness of VB binder. Laboratory experiments were conducted to compare the performance of the modified binder with the original hardened binder. The results showed that adding the rejuvenator improved the properties of the VB binder. Optimal asphalt grades were achieved with a 2% content of the softening additive in the VB binder. The rejuvenator enhanced moisture resistance, leading to settlements comparable to the control asphalt. Settlements after 20,000 load repetitions were 11.49 mm for the modified mixture, which were slightly better than the control material at 12.44 mm. Moisture stripping points occurred at around 16,000 cycles for the modified mixture, while the control material experienced them at approximately 13,000 cycles. Under freeze-thaw cycles, the modified mixture exhibited enhanced durability compared to the control mixture. The control mixture experienced a significant increase in rutting value of approximately 59.7% (from 12.4 mm to 19.7 mm), while the modified mixture showed a relatively lower increase of approximately 37.4% (from 11.5 mm to 15.8 mm). Additionally, the modified VB mixture demonstrated approximately 7.8% higher dynamic modulus at lower temperatures, indicating improved mechanical properties. It also displayed superior fatigue crack resistance, with a fatigue life of 18,385 cycles compared to 15,775 cycles for the control asphalt. Field results confirmed that the VB asphalt mixture with the rejuvenator achieved comparable site compactness to the control mixture, indicating successful compaction performance. These findings highlight the rejuvenator’s efficacy in mitigating binder stiffening and restoring the original state of aged asphalt binders.

This paper conducts an in-depth study and evaluation of pedestrian paths, with a particular focus on the anti-slip performance and walking comfort of wooden chip pedestrian walkways. Through controlled experiments, a comparative analysis was performed between wooden chip pedestrian walkways and ordinary paved brick walkways. The experimental results indicate that under dry conditions, the anti-slip performance of various road surfaces is good. However, in wet environments, the anti-slip performance of paved brick roads deteriorates significantly. In contrast, wooden chip pedestrian walkways, especially those mixed with asphalt and wood chips, exhibit excellent anti-slip properties and comfort. Additionally, the study reveals that the comfort of wooden chip pedestrian walkways is significantly better than that of paved brick walkways, and the comfort of asphalt materials is slightly better than emulsified asphalt. It is worth mentioning that fine wood chips provide less comfort than coarse wood chips. Although reducing the thickness can enhance comfort, considering the service life of the road, a thickness of 4–6 cm is most suitable. Finally, asphalt and wooden chip mixtures with coarse wood chips possess good water permeability, making them suitable for permeable drainage pavement designs, effectively reducing road surface water accumulation.
