【摘要】 沥青路面早期破损的原因之一就是水害,特别是路面结构内存在滞水,在车辆行驶作用下,就会使沥青混凝土路面出现龟裂、唧浆、破碎、凹陷和坑洞等破坏.对河南开封尉氏至扶沟的二级公路采用的沥青稳定碎石排水基层沥青路面的结构特性,对其排水能力和力学性能进行分析.更多还原

【Abstract】 Flood is one of the reasons for asphalt pavement damaged in the early stage.If there is a water detention in the structure of asphaltpavement,especially heavy traffic,the pavement is always damaged with splits and mud or water may ooze from underground.In view of the structural features of asphalt pavementwith drainage base level built of asphalt stabilized broken stones adopted in the second-class highaway from Kaifeng Weishi to Fugou,this paper has expounded its drainage capcity and the function of mechanics.更多还原
