大空隙沥青稳定碎石排水基层可以有效防治沥青混凝土路面早期水损害。在参考国外研究成果的基础上,通过室内试验的不断调整,最后确定出3种典型级配,并总结出大空隙沥青混合料沥青最佳用量的确定方法。
Large gap asphalt stabilized gravel drainage base can effectively prevent the early water damage of asphalt concrete pavement. Based on the research results of foreign countries, three kinds of typical grading were finally determined through the continuous adjustment of laboratory tests. The determination of the best dosage of large-gap asphalt mixture asphalt was summarized.
