Abstract

Abstract

In order to ascertain the rational control index of run-off loss for porous asphalt mixture, based on the perspective of low run-off loss and adequate strength and durability, optimum asphalt content was selected through laboratory run-off test and Cantabro abrasion test, it was compared with the content selected in current specification, and the influences of different types of fine aggregates were investigated.Analysis result shows that the index in current specification is not more than 0.3%, it is irrational for porous asphalt mixture, so a new index is put forward, it is not more than 0.8%.In the construction of test road, all properties of porous asphalt mixture have little variety, the main properties are superior to that in current specification, so the index is rational, which ensures the quality stability of pavement construction.
