【 摘 要 】

In order to evaluate road performance of Warm mixed reclaimed asphalt (WMRA), the tests are carried out. Different blended ratio(10%, 30%, 50%) of RAP(recycled asphalt pavement) is selected, and WMRA and Hot mixed reclaimed asphalt mixture (HMRA) are designed respectively. Through the test analysis, the method to determine WMRA optimal mixed temperature, molded temperature and heated temperature of new aggregate is established. Marshall test, rutting test, low temperature bending test, residual stability test and freeze-thaw splitting test are conducted, and Marshall indicators and road performance of HMRA and WMRA are finally evaluated.
