| Abstract: | In order to study the results of modified asphalt composited with waste rubber powder and SBS, this paper analyzed the modified mechanism of polymer modified asphalt. The composite modification was done with 20% crumb rubber and 0. 5%, 1%, 1.5%, 2% SBS, compared the main indexes of composite modified rubber asphalt with ordinary rubber modified asphalt, and studied the effects of SBS content on rubber asphalt. The result showed composite modified rubber asphalt could achieve better high and low temperature performance than ordinary rubber asphalt. |
