摘要
分析了水泥混凝土加铺沥青混凝土面层后路面可能出现的病害,采用力学分析法对出现这些病害的原因进行分析,得出影响加铺后面层出现病害的主要因素为水泥混凝土板表面光滑、板底脱空、板间错台和接缝填缝料缺损等,提出防止或减缓出现这些病害的措施,并结合贵阳东出口水泥混凝土路面加铺沥青混凝土面层的工程实践,验证了本文提出的病害处理措施具有较强的施工操作性。
This paper analyzes possible defects and damages on pavement after laying asphalt concrete surface course on cement concrete pavement, it adopts mechanical analysis method to analyze causes of such images and defects, and it concludes that the major factors that influence the damages and defects on added surface courses are smooth concrete slab surface, hollow underneath slab, stagger slabs and lacking butting packing, etc.. It suggests ~ures to prevent or relieve these defects and damages, and integrated with engineering practices for laying asphalt concrete surface course on cement concrete pavement at east exit of Guiyang, it proves the damage ＆ defects treatment measures suggested in this essay has relatively good construction operability.
