Method for repairing drainage asphalt pavement
A method for repairing a drainage asphalt pavement comprises the following steps: firstly, prefabricating a compact asphalt block body and a permeable asphalt block body, cleaning pits of the asphalt pavement, and shoveling an original compact asphalt layer or only shoveling a permeable asphalt layer; and then supplementing the dense asphalt block body and the permeable asphalt block body in sequence, or reserving the dense layer and only supplementing the permeable asphalt block body at the upper part. The method has the advantages that the effects that the surface layer in the damaged pit is permeable and the middle layer is dense and waterproof can be kept, so that the asphalt base layer is prevented from being damaged by accumulated water, the bearing and pavement stabilizing effects of the base layer can be ensured, and the extrusion damage phenomenon caused by the elasticity modulus difference of different asphalt layers can be prevented.
一种排水沥青路面的修补方法，先预制出密实沥青块体和透水沥青块体，把沥青路面凹坑处进行清理，将原有的密实沥青层铲除或者仅仅将透水沥青层铲除，然后先后补入密实沥青块体和透水沥青块体或者保留了密实层仅仅补入上部的透水沥青块体。具有既能够保持损坏凹坑内的表层透水、中层密实防水的效果从而防止沥青基层遭到积水的破坏，又能够保证基层的承重和稳定路面的作用，也可以防止因为沥青不同层弹性模量差异导致的挤压破会现象出现的优点。
