水泥混凝土桥面沥青铺装层施工厚度控制技术

Control Technology on Construction Thickness of Asphalt Concrete Pavement for Concrete Bridge Deck

通过采用有限元计算分析水泥混凝土桥面沥青铺装层厚度变化对铺装层底纵、横向剪应力的影响,提出改善桥面铺装层施工厚度和平整度的施工工艺及分析评价铺装层施工厚度的可靠度计算方法,并通过实体工程的实践检验,取得了良好的施工效果,这对指导混凝土桥面沥青铺装层施工具有一定的借鉴意义。

By using the ANSYS to analyze the influence of longitudinal shear stress and transverse shear stress of asphalt concrete layer bottom with the different thickness of asphalt concrete pavement for concrete bridge deck, the construction technology and the reliability calculation method are put forward to improve and evaluate the construction thickness and the smoothness of asphalt concrete pavement for concrete bridge deck. Meanwhile, through the practical test of entitative engineering, the good construction result has been achieved. All these will have certain reference to guide the asphalt concrete pavement for concrete bridge deck.
