Abstract: Highly modified styrene-butadiene-styrene–modified asphalt (SBSMA) with an SBS content of 6–9% is gaining popularity in China as an efficient binder for open graded friction course pavement. However, the short-term aging ...

Abstract: Polymers have been incorporated into asphalt as a way to mitigate permanent deformation at high performance temperatures for many years. There are several types of polymers used in asphalt binders to improve the rheological ...

Abstract: This work evaluated the effect of polymer and polyphosphoric acid (PPA) on the aging resistance of different asphalt binders with pressure-aging-vessel (PAV) aging. Two base asphalt binders, three polymers, one recycled ...

Abstract: The sigmoidal master curve model can be used to obtain the value of dynamic modulus of asphalt mixtures at a high or low temperature, which cannot be obtained directly from laboratory tests. However, some studies indicated ...

Abstract: AbstractThe oil–water interfacial film formed by emulsifier molecules adsorbed around asphalt droplets affects the stability of emulsified asphalt. This study investigated the stability of emulsified asphalt by characterizing ...
