Abstract: This study aims to investigate the fatigue behavior and healing properties of aged asphalt binders. Both 70# and SBS-modified asphalt binders were aged using a rolling thin-film oven test (RTFOT), and their physical ...

Abstract: In the experiment, a heat-reflective coating (HRC) was applied to the surface of asphalt pavement. The coating temperature reduction principle and the mechanism to mitigate the urban heat island effect (UHI) were explored ...

Abstract: This study aims to evaluate the effect of microwave radiation on the self-healing performance of asphalt mixture. Fracture-healing-fracture test was conducted via semicircular bending (SCB) test and microwave heating. The ...

Abstract: To identify the key influencing factors and optimal healing conditions for the self-healing ability of bituminous binders, a fatigue-healing-fatigue test was performed under different conditions by the time-sweep mode of ...

Abstract: In this study, heavy calcium carbonate was wet modified using a titanate coupling agent, and fabricated titanate-coupled calcium carbonate and styrene–butadiene–styrene (SBS) were used to prepare composite modified asphalt. ...

Abstract: This study aims to develop a prefabricated flexible ultrathin overlay that can quickly and effectively repair cracks, particularly reticulation cracks, in old asphalt pavements while improving skid resistance. The overlay ...

Abstract: Phosphogypsum (PG) is an industrial solid waste generated during the preparation of phosphoric acid, which is produced in large quantities and stockpiled or discharged into the sea. This study aims to design sustainable ...

Abstract: Waste tires, used in combination with polymers, have been extensively employed in the construction of asphalt pavements. The performance of these hybrid asphalts varies depending on the manufacturing process, the characteristics ...

Abstract: Interface bonding between different asphalt pavement layers is crucial in maintaining the integrity of the pavement structure. To improve the interface bonding, bitumen emulsion is commonly used as the tack coat material. ...

Abstract: Adding graphene microflakes with excellent mechanical properties to asphalt materials can promote the development of sustainable transportation infrastructure. Recently, graphene oxide–modified asphalt has gained popularity ...
