G3京台高速公路徐州绕城段沥青路面病害影响研究OA

To study the influence relationship between asphalt pavement diseases and pavement evaluation indicators as well as traffic volume,the RTM intelligent road detection system was adopted to detect and analyze the inter-national roughness index and pavement damage rate and other evaluation indicators of the asphalt pavement on the Xuzhou Ring Section of G3 Jing-Tai Expressway.Meanwhile,the existing traffic volume of the section,the determination of traffic grade and the distribution coefficient of vehicle types were statistically analyzed.The results show that the asphalt pavement technical status assessment grade of the inspection section is mid-dle grade.Under the coupling action of the traffic age and the driving load,the asphalt pavement has rutting,cracking and other diseases,which have affected the driving comfort and safety performance to a certain ex-tent.Further targeted maintenance and treatment measures are needed.
