【摘要】 为探明某公路沥青路面出现开裂破损原因,在介绍地质雷达工作原理的基础上,采用地质雷达对某公路沥青路面病害进行了探测,并结合弯沉值、密实度与含水率等测试结果,验证了地质雷达探测结果的准确性和有效性。研究结果表明:公路下部存在不密实区、富水松散区以及不均匀沉降变形区,是导致沥青路面开裂破坏的重要原因。更多还原

【Abstract】 In order to identify the causes for cracking breakage of bituminous pavement of a road,the disease of bituminous pavement of a road is detected by the GPR after description of the operating principle of the GPR,and the accuracy and validity is verified for the detection result obtained by the GPR by deflection value,compactness,moisture content and other testing result. The study results show that an uncompacted area,a water-rich loose area and an uneven settlement and deformation area exist under the road,which are major causes for cracking breakage of bituminous pavement.更多还原
