Intersection rubber asphalt anti-rutting pavement detection and design method based on ground penetrating radar
The invention discloses an intersection rubber asphalt anti-rutting pavement detection and design method based on a ground penetrating radar, and the method comprises the steps: 1, dividing a left-turning vehicle parking region, a straight-going vehicle parking region and a bus parking region into dynamic-static load regions according to the principle of dynamic and static load separation and in combination with the distribution characteristics of intersection traffic flow; and dividing a right-turning lane into a dynamic load area; and 2, measuring the thickness of the residual road surface at the damaged parts by utilizing a reflection coefficient method at the damaged parts of the base layers and the damaged parts of the surface layers of the dynamic-static load areas and the dynamic load areas. The road surface thickness is calculated based on the ground penetrating radar, the problems that the number of samples is limited, the road surface is seriously damaged and the whole damage range cannot be measured in a core drilling sampling method are solved, meanwhile, a corresponding transformation scheme is set according to the non-uniform coefficient range, and the defects that traditional intersection transformation, partial damage and overall removal are needed, the workload is large; and the repairing effect is poor are overcome.
本发明公开了一种基于探地雷达的路口橡胶沥青抗车辙路面检测和设计方法，第一步：根据动静荷载分离的原理，结合交叉口车流的分布特点，将左转车辆停驻区、直行车辆停驻区、及公交车停驻区划分为“动‑静荷载”区域；将右转车道划分为“动荷载”区域，第二步：在“动‑静荷载”区域”和“动荷载”区域的基层破坏处与面层破坏出，利用反射系数法测量破坏处的剩余路面厚度。本发明基于探地雷达计算路面厚度，克服了钻芯取样法样本数有限、对路面损坏严重且无法对整个破坏范围测量的问题，同时，根据不均匀系数范围，设置对应改造方案，克服了传统的交叉口改造，部分损坏，需要整体清除，工作量大且修复效果差的问题。
