旧水泥混凝土路面加铺沥青面层关键技术探讨

Discussion of the Key Techniques about Paving Asphalt Concrete adding on the Old Cement Concrete Road Surface

通过对沥青加铺路面反射裂缝成因的分析,提出旧水泥混凝土路面加铺沥青面层的关键技术,并结合324国道莆田城区段道路改造的工程实例,阐述道路"白改黑"的路面结构设计思路及方案比选,对类似项目有一定的参考价值。

Abstract： Through the analysis of the causes for the reflection cracking of the placing asphalt pavement, the key techniques of the placing asphalt surface adding of the old cement concrete pavement were put forward. Combined with the engineering example of the road recon- struction for the 324 national highway of the main urban section in Putian Area, the design method of the pavement structure and scheme selection for Add - surfacing AC layer on the PCC was expounded, which has some certain reference value to similar projects.
