Abstract—

The aim of the study is to develop a method for predicting the residual life of road surfaces on highways based on the analysis of energy dissipation under the dynamic influence of transport. To solve this problem, the method of analyzing its stress-strain state is applied, based on the exact solution of the dynamic Lame equation, which allows constructing the amplitude-time characteristics of displacements, strains, and stresses. Based on the constructed amplitude-time characteristics of stresses and strains, a dynamic hysteresis loop is constructed, the area of which corresponds to the volume of dissipation energy in the structure of the pavement for a single deformation cycle. Based on the presented computational approach, a method for determining the calculated total energy dissipation in the structure of the pavement over the service life was developed. Using the FWD shock loading unit and a mobile diagnostic laboratory, an experimental method for determining the total energy dissipation over the service life of the pavement was developed. Their comparison allows predicting wear and determining the residual life and service life of road coverings on highways as well as assigning corrective measures for their restoration.

基于交通动态影响下能量耗散分析的公路路面剩余寿命预测

摘要——

该研究的目的是开发一种基于交通动态影响下的能量耗散分析来预测高速公路路面剩余寿命的方法。为了解决这个问题，采用基于动态拉梅方程精确解的应力-应变状态分析方法，可以构建位移、应变和应力的幅值-时间特性。基于所构建的应力和应变的幅值-时间特性，构建了动态磁滞回线，其面积对应于单个变形周期路面结构中耗散能量的体积。基于所提出的计算方法，开发了一种确定使用寿命期间路面结构中计算的总能量耗散的方法。使用 FWD 冲击载荷装置和移动诊断实验室，开发了一种确定路面使用寿命内总能量耗散的实验方法。通过比较，可以预测磨损并确定高速公路道路覆盖物的剩余寿命和使用寿命，并为其修复指定纠正措施。
