| description abstract | The objective of this paper is to evaluate the effect of different aging times on the performance of styrene-butadiene-styrene (SBS) copolymer–modified asphalt. Two kinds of SBS-modified asphalt with different SBS contents were selected, and a self-developed indoor aging equipment simple-aging test (SAT) was used to age the SBS asphalt binder for different times and different temperatures. The penetration, softening point, ductility, and Brookfield viscosity of the aged samples were tested, and the rheological properties of the aged samples were tested by dynamic shear rheometer (DSR). It was found that the rheological behaviors of the aged samples at high, medium, and low temperatures were closely related to the aging time and SBS contents. In addition, during certain aging temperatures and times, different physical and rheological indexes showed that the performances of SBS-modified asphalt after SAT was similar to that after rolling thin-film oven test (RTFOT) and pressurized aging vessel (PAV). | |
