摘　　要：目的针对沥青路面车辙病害出现的不同类型,利用路面雷达进行车辙类型的识别研究.方法根据各种车辙病害形成的机理提取不同类型车辙的几何特征要素,在雷达实地检测后对数据进行处理和分析,建立几何特征要素和实测数据间的联系以实现对车辙类型的识别.结果通过对两个具体车辙断面的类型识别实例介绍了车辙类型识别的方法,识别所得结论与取芯试验结果相比有着很好的一致性.结论将路面雷达应用于沥青路面车辙类型的识别不仅有较好的准确性和可靠性,还具有现今检测技术所具备的无损、快速、便捷等优点,该技术的提出对于沥青路面车辙病害研究有着重要的意义和较大地帮助.To address different patterns of rutting disease in asphalt pavement, ground penetrating radar （GRP） was used for rutting recognition. Based on the analysis of rutting types, some researches were carried out to get geometry characteristic factor of various rutting pattern. GPR was used to collect data in the test road for asphalt pavement detection. The data after processing could be calculated to get relation to the geometry characteristic factor, and the pattern of rutting disease could be confirmed accordingly. Two test examples were done to introduce this recognition method, and the conclusion indicates that the recognition results have good consistency with drilling-hole core test. As a rutting pattern recognition tool, GPR not only has a better accuracy and reliability, but also has the features of being non-destructive, rapid, convenient, etc. The technology proposed in this paper will do good for the future research of rutting disease in asphalt pavement.
