- Abstract:
- To improve the quality of Xinjiang Tahe asphalt, this paper studies the performances of base90#, skillimproved90#, municipaldedication90#, SBS modified asphalt, SBR modified asphalt by using the indices of Chinese standard Technique Specification for Highway Asphalt Pavement Construction and SHRP(Strategic Highway Research Program). The influences of properties of crude oil and production technology on the road performances of asphalt are conducted through experiments. The result shows that the good performance at high temperature and bad performance at low temperature of basis asphalt is determined by the high content of asphaltine, the road performance at low temperature can be improved only through optimizing the contents and adding modifier in the production. 3 tabs, 3 figs, 8 refs.
