摘要
通过对佛山市一环高速公路改造路面方案的研究,探讨了在检测中实测弯沉数据、路面结构强度指数评价与路况调查结果相悖情况下的路面结构计算方法,指出了弯沉指标在反映沥青路面强度方面存在着一定的局限性。同时分析了不同加铺厚度对原有软基沉降未稳定路段的二次沉降影响。
Through the study on the pavement reconstruction scheme of Ring I Expressway in Foshan City,this paper discusses the calculation method of pavement structure under the condition of the measured deflection data and pavement structure intensity index evaluation different from the survey result of road situation, points out the deflection index has a certain limitation in the reflection of the asphalt pavement strength, and also analyzes the influence of the different overlaying thicknesses on the secondary settlement of the unstable road section of the original soft foundation settlement.
