水泥混凝土桥面板与沥青铺装由于层间抗剪强度不足易发生推移、拥包病害。文章通过改变环境温度与正压力两项参数,对不同界面水泥混凝土桥面板与沥青铺装进行层间直剪试验,得出水泥混凝土桥面板表面纹理对层间抗剪强度有显著影响,并可通过改善桥面板与沥青铺装结合面的粗糙程度来提高桥面铺装的抗剪强度和层间稳定性能。 Cement concrete bridge deck and asphalt pavement due to the lack of shear strength is prone to happen, contracting disease. Through changing the parameters of ambient temperature and positive pressure, the paper carries out the direct shear test of concrete between different interface cement concrete bridge deck and asphalt pavement, and draws the conclusion that the surface texture of cement concrete bridge deck board has significant influence on the shear strength of interlayer, Improve the shear strength and interlayer stability of the deck pavement by improving the roughness of the bridge deck and the asphalt pavement.
