| Abstract: | Warm-mixed rubber asphalt modified by Sasobit warm asphalt additive is a new material.In order to analyse the influences and laws of the high-temperature performance of warm-mixed rubber asphalt which is impacted by Sasobit,regular performance tests,viscosity properties tests,and high-temperature performance tests of mixture with different percent of Sasboit were carried out.Finally,the results showed that the best percent of Sasobit is 3%,the temperature of reducing viscosity of Sasobit is approximately 20 ℃. |
