旧沥青路面上直接加铺水泥混凝土面层的应用研究

Application Research on Direct Spreading Cement Concrete Surface Pavement on Old Asphalt Pavement

对旧沥青路面的病害进行挖补维修处理后,在其上直接加铺常用板块尺寸的普通水泥混凝土面层。通过对影响混凝土加铺层的各种因素的力学分析,明确了旧沥青路面加铺水泥混凝土路面前的病害处理措施,确定了加铺层厚度。试验路运营情况表明,路面使用状况良好。

After maintenance of excavation and filling for old asphalt pavement, common size cement concrete pavement is directly paved on old asphalt road surface. Based on the analysis of influencing factors of spreading layer, the old asphalt pavement treatment measures and new spreading pavement thickness are defined. Practice shows that road is in good condition after treatment.
