【摘要】 对大粒径碎石沥青稳定排水基层混合料设计方法进行系统研究,提出排水性大粒径碎石沥青稳定基层级配,通过析漏试验、飞散试验和马歇尔试验确定最初沥青用量,并通过水稳定性试验、高温性能试验和疲劳性能试验,确定最佳沥青用量。更多还原

【Abstract】 Based on systematic research on mixture design method of large stone asphalt treated permeable base,grading of large stone asphalt treated permeable base has been brought forward,and initial optimum asphalt content has been ascertained using Schellenberg Binder Drainage test,Cantabro test and Marshall test.Then with moisture susceptibility test,high temperature behaviour test and fatigue behaviour test,optimum asphalt content has been ascertained.更多还原
