英文摘要: Abstract(#br)Terminal blend rubberized asphalt (TB), a rubber-modified asphalt, exhibits excellent storage stability and compatibility compared with traditional rubber modified asphalt. However, the investigation regarding its performance at high temperatures is not sufficient. In this study, the amorphous-poly-alpha-olefin (APAO) additive was employed as a modifier to improve the performance of the TB asphalt at both high- and low-temperature. Firstly, the general performance and rotational viscosity were tested via conventional tests in the laboratory. Besides, the rheological properties at both high and low temperatures were evaluated by a dynamic shear rheometer (DSR) test and a bending beam rheometer (BBR) test, respectively. Finally, the micromorphology of specimens was detected...
