加铺罩面是改善路面平整度的主要措施。在加铺罩面设计时,最重要的是确定加铺罩面层厚度、加铺罩面结构层混合料类型的选择等,其中加铺罩面层厚度又是影响养护措施效果最为重要的因素之一。从加铺罩面厚度及平整度角度出发,提出高速公路路面加铺厚度与平整度改善关系。此关系应用于工程实例结果表明:采用平整度指标验证路面设计加铺厚度,对于路面加铺厚度设计具有优化作用。
Overlay overlay is the main measure to improve the smoothness of the road. In the overlay design, the most important thing is to determine the overlay overlay thickness, overlay overlay structure layer mixture type selection, etc., which overlay overlay thickness is the impact of conservation measures the most important factor one. Based on the thickness and flatness of overlay, the paper proposes the improvement of pavement thickness and smoothness of expressway pavement. This relationship is applied to the engineering example. The results show that using the flatness index to verify pavement design pavement thickness has an optimal effect on the pavement thickness design.
