摘　　要：沥青路面厚度是交工验收中的关键检测指标,目前主要的检测方法有传统的钻芯法和短脉冲雷达检测法,其中传统的钻芯法检测效率较低,且会造成路面破损,而短脉冲雷达法是一种高效、连续、无损的检测方法。本文基于实际公路工程的检测,分析短脉冲雷达的检测原理和影响因素,对检测结果的误差进行对比分析,发现短脉冲雷达能够较准确地检测沥青路面厚度,并结合雷达检测的实际应用提出可行建议,为短脉冲雷达无损检测技术的应用推广提供依据参考。The thickness of asphalt pavement is the key in the completion of the acceptance test index.The main detection methods are the traditional method of core test and the short pulse radar method.The detecting efficiency of the traditional core method is low,and it can cause damage to the road.While the short pulse radar method is a kind of efficient,continuous and nondestructive detection method.Based on the detection of actual highway engineering,this paper analyzes the detection principle and influencing factors of short pulse radar,and makes a comparative analysis of the error of detection results.It is found that short pulse radar can accurately detect the thickness of asphalt pavement.Combining with the practical application of radar detection,this paper puts forward feasible suggestions to provide reference for the application and popularization of short pulse radar nondestructive detection technology.
