摘　　要：路面内部隐性病害的发育、发展具有隐蔽性,而当前缺乏有效的检测手段、评价指标和标准。依托溧马高速路面养护维修工程,通过基于三维探地雷达的路面隐性病害识别与评价研究,建立了路面内部典型隐性病害标准图谱,提出基层损坏状况指数BPCI及分级标准,并给出了不同等级路面内部隐性病害养护对策。研究结果表明:三维探地雷达可高效准确识别路面内部隐性病害,识别精度可达90%以上;基于三维探地雷达的基层破损状况指数BPCI,用于评价路面结构内部状况是可靠的,其探测结果可为路面内部隐性病害检测定位和沥青路面的养护施工提供参考。The formation and development of hidden defects inside the pavement are concealed,however,there is no effective detection methods,evaluation indicators and standards for this problem.Relying on the maintenance and repair project of Lishui-Ma'anshan Expressway,the hidden defects inside the pavement are identified and evaluated through three-dimensional ground penetrating radar.The standard map of typical hidden defects inside the pavement is established,and the base pavement condition index(BPCI)and grading standard are proposed.In addition,the maintenance measures for the hidden defects inside the pavement of different class highway are provided.The research results show that the three-dimensional ground penetrating radar can efficiently and accurately identify the hidden defects inside the pavement,and its recognition accuracy can reach more than 90%.The BPCI obtained by threedimensional ground penetrating radar is reliable for evaluating the internal condition of the pavement structure,and the detection results can provide an important reference for the positioning of hidden defects inside the pavement and the maintenance measures of asphalt pavement.
