摘要
利用室内直槽修筑的四段典型的半刚性基层沥青路面结构，对其弯沉和拉应力进行测定，并对实测值和理论值进行对比分析，验证交通部“八五”科技项目“沥青路面设计指标与参数的研究”推荐的路面材料设计参数、弯沉综合修正系数与拉应力计算等的合理性。通过大量的实测数据和分析计算表明，推荐的设计参数和设计方法是合理的，可纳入设计规范，应用于工程设计。
Some design parameters and method for an asphalt pavement with a semi-rigid base are proposed in the paper. There are four experimental sections of the typical asphalt pavement with a semi-rigid base constructed in the indoor straight pit. An attempt is made to investigate the deflections and the tensile stresses of an asphalt pavement. The tested results were compared with that of the theoretical. The compared results are shown that the proposed some design parameters and method are feasible. This is a useful reference for the code editors and the engineers.
