摘要
为了对比分析高速公路修复工程中不同修复方案的抗车辙效果,采用不同的沥青混合料类型组成不同路面结构组合方案,在沥青混合料高温稳定性室内试验评价的基础上,铺筑试验路并进行跟踪观测。将各种类型沥青混合料室内车辙试验结果、试验路不同路面结构组合方案使用3年后的车辙深度检测结果与该试验路交通量组成进行对比分析发现:交通量和轴载是沥青混凝土路面使用过程中车辙深度的关键影响因素,我国的技术规范根据不同类型沥青混合料抗车辙能力确定技术要求的同时,更应根据交通量及轴载组成制定路面结构抗车辙能力的技术标准。
To evaluate the rutting resistance of kinds of rehabilitation ways of expressway, different kinds of pavement structure are made by several kinds of asphalt mixtures, on the basis of the laboratory experiment data of high temperature stability, the test road is constructed and observed. According to the traffic volume composition, the rutting test results and rutting depth of test road which is observed after three years service are compared. The results reveal that traffic volume and the axial load are the key factors which influence the rutting depth of asphalt pavement during service. The rutting resistance technique criterion of different pavement structure based on the traffic volume and the axial load should be constituted.
