Pavement Performance and Application Technology of Warm Mix SMA Asphalt Mixtures

To compare the WMASMA—13 with SMA—13 about pavement performance and gas emissions detection,the result shows that pavement performance of the two are almost the same,and poisonous gas emissions concentration and emission rate of WMASMA—13 are far below SMA—13.The site construction technique of WMASMA—13 is concluded.Through field tests of test road,it is found that all the index of WMASMA—13 accord with requirements.
