摘　　要：为了确定合理的析漏损失控制指标,通过室内析漏与飞散试验,根据析漏较小而强度和耐久性佳的原则,确定了排水性沥青混合料的最佳沥青用量,与满足现行规范析漏要求确定的沥青用量进行了对比分析,并研究了细集料对混合料析漏损失的影响。分析结果表明:现行的规范析漏损失不大于0.3%指标是不合理的,提出以不大于0.8%作为排水性沥青混合料析漏损失的控制标准,施工中混合料的各项性能指标的变异性小,主要性能指标的检测结果均优于技术要求,确保了排水性沥青路面施工质量的稳定性。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. 4 tabs, 4 figs, 8 refs.
