【摘 要】针对刚柔复合式路面界面层所受剪应力,运用功能原理建立界面层剪应力简化计算模型。分析车辆在不同行驶速度和刹车距离情况下,刚柔性路面界面层所受到的剪应力大小。计算结果显示:在行驶速度为120Km/h,刹车距离为50m时,界面层所受到的最大剪应力不会超过0.778MPa。【关键词】刚柔性路面;界面层;剪应力;功能原理;防水粘结层【Abstract】Rigid Composite Pavement interface layer suffered shear stresses, using functional principles of the establishment of boundary layer shear stress, simplify the calculation model.
