通过足尺试验对UTW试验路进行了结构性能试验和评价。通过分析试验路弯沉变化及动态模量,对路面整体承载能力进行了分析和评价;通过裂缝观察及结构性能评价对方案进行了比较分析。从试验结果及评价结果来看,不同方面的评价结果具有很好的一致性,各方案结构性能从好到差的排序依次为:方案三>方案四>方案五。评价结果也揭示出,基础强度和恰当的结构组合对路面的使用性能影响显著。
Through the full-scale test on the UTW test road structure performance test and evaluation. By analyzing the deflection and dynamic modulus of test road, the overall bearing capacity of the pavement is analyzed and evaluated. The scheme is compared and analyzed through the observation of cracks and the structural performance. From the test results and evaluation results, the evaluation results of different aspects have good consistency, and the rankings of each program structure performance from good to bad are as follows: Scenario 3> Scenario 4> Scenario V. The evaluation results also reveal that the basic strength and the proper combination of structures have a significant impact on the performance of pavement.
