摘要

Different kinds of plasticizers and crosslinkers were used to prepare high-viscosity modified (HVM) asphalt and high-elastic modified (HEM) asphalt and the major physical properties were studied and compared. The kinds of plasticizers were optimized and the difference in composition between HVM and HEM asphalts was clarified. The plasticizers with different thickness and flexibility were available for HVM or HEM asphalts respectively. The kinds of crosslinkers were also compared and optimized and it was found that the most effective crosslinker was sulfur. The effect of anti-ageing reagent on HEM asphalt was confirmed and it was found that one of the most effective way to retain the properties of HVM and HEM asphalt before ageing was to increase the SBS content further.
