    Abstract

    In an effort to study sustainable environmentally friendly pavement, the physical mechanics and road performance of warm-mix asphalt mixtures based on an emulsifying platform were studied via the Marshall design method. The results show that the optimum asphalt content of warm-mix asphalt mixtures is generally higher than that of hot-mix asphalt mixtures by 0.1 % to 0.2 %; the values of the stability, bulk specific gravity, air voids, and voids in mineral aggregate do not change significantly; and the number of voids filled with asphalt and the flow value increase a little. The residual stability value of warm-mix asphalt mixtures increases, whereas the freeze–thaw splitting strength decreases. The high-temperature performance and seepage performance of warm-mix asphalt mixtures are similar to those of hot-mix asphalt mixtures.
