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 ...
Investigation of the Morphological Characteristics and Chemical Properties of Hardened Layers in Polymer-Modified Asphalt during Aging
Publisher: American Society of Civil Engineers
Abstract: AbstractDuring the aging process, the surface layer of asphalt binders gradually hardens and
forms wrinkles; this hardened layer provides a certain degree of protection to the
underlying asphalt binder. This study aims to ...
