水泥混凝土路面的沥青联接层作用初探

Primary Study of asphalt binding course applied in Concrete Road

上世纪90年代前后期施工通车的水泥路面在长期荷载作用下,进入损坏和维修的高峰期,由此引出水 泥路面结构优化问题。为此,根据沪闵路加固的结构特点和十几年来良好的路面运行状况分析,提出在刚性水泥混 凝土面层与其半刚性基础之间应增设沥青联接层作为柔性缓冲和基础保护的建议。

It has caused a peak period of damage and maintenance of the concrete roads built in early or later 90s. It brings out a question that how to optimize the structure of the concrete roads. According to the analysis of structure character of the Huming reinforced road with good performance of this road for more than ten years, we suggest to add asphalt binding course between rigid concrete surface and semi-rigid basement.
