水泥混凝土桥面沥青铺装层厚度的研究

Research on the Thickness of Asphalt Concrete Pavement for Concrete Bridge Deck

通过对常见防水层材料和层间结合料进行直剪试验 ,采用弹性层状体系理论 ,对水泥混凝土桥桥面层间剪应力进行了力学计算与分析 ,并结合防水层、平整度、施工工艺和车辙指标的要求 ,提出了桥面沥青铺装厚度的计算方法 ,在此研究基础上 。

Based on the shearing test of waterproofing and inter layer coherence materials,elastic multi layer theory is used to calculate and analyze the shearing stress between AC and concrete bridge deck.With the consideration of waterproof layer,roughness,construction technique and rut depth,the proper thickness of asphalt concrete pavement for concrete bridge deck is derived.Furthermore,the adequate structure of asphalt concrete for concrete pavement bridge deck is recommended.
