高速公路路况调查及FWD检测数据分析

Highway condition survey and FWD detection data analysis

介绍在某高速公路修建橡胶沥青碎石封层加铺4 cmSMA-13沥青混合料试验路情况。对试验路段进行了路况调查发现,该段试验路在同类型病害中较严重。对修筑前后的试验段分别进行FWD检测和数据对比分析,对典型病害处进行重点FWD检测,并通过弯沉数据分析,提出修补建议。

This paper introduces the construction of 4 cmSMA-13 asphalt mixture test road in a highway with rubber asphalt gravel sealing layer. The road condition investigation of the test section shows that the test section is more serious in the same type of disease. FWD detection and data comparative analysis were carried out on the test sections before and after the construction, and key FWD detection was carried out on the typical diseases, and repair Suggestions were put forward through the analysis of bending and sinking data.
