水泥混凝土路面加铺沥青混凝土技术质量控制

Technique Quality Control Of Cement Concrete Pavement Adding Bituminous Concrete

旧水泥混凝土路面加铺沥青混凝土面层是一种特殊的路面结构,其应力、应变特性与一般的弹性层状体系有较大的差别,质量控制涉及到旧水泥混凝土板的处理、反射裂缝的防治、加铺层厚度控制、面层材料的选择、提高路面的抗渗性能等关健环节。

Spreading bituminous concrete on old cement concrete pavement is a special pavement structure.Its stress and strain characteritics are different with common elasticity layer system.Its quality control is concerned in the treatment of old cement concrete slab,the prevention of reflection crack,the adding width control,material selection and improving pavement leakage proof property.
