摘要
沥青路面的压实质量是控制其工程质量的关键指标。路面雷达作为一种高效、快速、连续、无损的路面检测设备,其应用技术的研究自20世纪90年代以来一直是国际上的热门课题。路基材料介电特性的差异是路面雷达应用的先决条件,利用混合料的介电特性与其组成的固态、液态、气态三相体的相关关系,进而基于路面结构层材料介电特性,将路面雷达无损检测技术应用于沥青路面压实质量检测评价中,开拓了路面雷达的应用领域和范围。
The compaction quality of the asphalt pavement is a key index to control engineering quality.As an effective,speedy,continuous and nondestructive testing equipment,the study on application of Ground Penetrating Radar（GPR） in pavement has been popular all over the world since 1990s.The precondition of GPR application is the difference of dielectric properties of roadbed material,using dielectric properties of mixture and the correlation of its solid state,liquid state and gas state,and then based on the dielectric properties of material for pavement layers,GPR nondestructive testing technique is used in compaction quality inspection of asphalt pavement,the application field and scope of GPR nondestructive testing technique is widened.
