Abstract: Permanent deformation of asphalt mixture under repeated load can be divided into three phases: decelerating phase, stationary phase, and accelerating flow phase. Most of the existing models cannot fully describe deformation ...

Abstract: The continuous pollution of waste plastics to the ecological environment has attracted global attention. Using waste plastics in road construction can save energy, reduce pollution, and improve the high-temperature performance ...

Abstract: In wet process–modified asphalt, the modifier is easily separated from the asphalt, resulting in poor storage stability. For traditional dry-mixed modified-asphalt mixtures, adding a single modifier to the mixture, it is ...

Abstract: Styrene-butadiene-styrene (SBS) modified asphalt binder after aging seriously affects the performance of the road. In this study, waste edible oil, SBS modifier, plasticizer and antiaging agent were used to prepare a new ...

Abstract: Liquid rubber (LR) has been proven to be a valuable asphalt modifier capable of addressing the existing deficiencies associated with crumb rubber–modified asphalt (CRMA), including poor workability and storage stability. ...

Abstract: Two kinds of asphalt binders and four kinds of aggregate gradations were selected. Cylinder specimens of six types of asphalt mixtures were molded by the superpave gyratory compactor (SGC) rotary compaction method, and ...

Abstract: In order to solve the problem of semirigid base damage in the initial period of use, this paper focused on emulsified-asphalt cold recycled mixtures with all old mineral and analyzed its strength formation mechanism. The ...

Abstract: The reuse of high content of reclaimed asphalt pavement and reclaimed asphalt shingles in hot mixtures by adding recycling oils has attracted wide attention and interest in the paving industry. However, the aging property ...

Abstract: Crumb-rubberized asphalt (CRA) binder has been widely used for several decades because it provides a nonhazardous disposal method for scrap tires and it improves some engineering properties of asphalt pavement. The energy ...

Abstract: Existing low-noise pavement has gradually lost its function with the development of urban road traffic. A poroelastic road surface (PERS), mainly composed of tire rubber granules, polyurethane, and aggregate, is considered ...
