沥青路面双层同时摊铺的必要性及施工工艺分析

The necessity of simultaneous double layersspreading for bitumen road surface and analysis of construction operation technics

沥青路面由多个结构层组成,传统的施工工艺易造成层间粘结力下降甚至其它病害,同时沥青路面养护及大修后,也极易产生沥青层间粘结力不足等缺限。文中就此问题进行探讨,为新建沥青路面或改建沥青路面提供借鉴。

The bitumen road surface consists of many constrction layers. The traditional construction operation technics may cause the drop of cohesion between layers and other faults. Also, after the maintenance and overhaul of the bitumen road surface, the cohesion deficiency may easily arise between the pitch layers. This article deals with these problems so as to offer some reference for building and rebuilding bitumen roads.
