摘要：
Double-layer porous asphalt (DLPA) pavement has been gradually applied in China for its efficient water drainage and noise reduction. However, it also faced the challenge of relatively low overall performance for the large air voids. This paper proposed a method of optimizing DLPA structure into a thinner three-layer porous asphalt (TLPA) structure for achieving lower air voids. Specifically, the optimal thickness of porous asphalt (PA) was determined by analyzing the relationship between PA mixture thickness and the degree of segregation. Then the application rate of tack coat between the mid...
