Study On Disease Analysis And Treatment Of Zibo Section Of Qingyin Expressway

Expressway as an important part of national infrastructure project,for people’s travel brings a lot of convenience.However,when the expressway operation after a period of time,there will be all kinds of diseases;After the maintenance and repair,diseases turn up again.Expressway diseases has many forms,including cracks,water damage,rut,subsidence,repair bad and breakage of the surfacing layer,the reasons for the formation of each disease each are not identical,qingdao-yinchuan high-speed zibo period of almost all disease.For high-speed disease management work,we need combinating with the practical situation of engineering and testing results to analyze the causes of diseases,and seek to conform to the engineering practice of preventive maintenance measures.This paper introduces the Qingyin common disease kinds of high-speed section of Zibo,and the common cause of the disease on the expressway system was analyzed,and then explained the expressway pavement detection related work,including the test and the results of the evaluation of both.We mainly tested the roughness,rut,and pavement damage,and the results show that the section of the road is good.But disease s including ruts and cracks often happened in a small scale,and these diseases will be repeated after the treatment,which has reasons more similar as before.Finally we put forward two measures to solve this problem:LLMO and Synchronous Fiber Abrasion.Considering traffic load and temperature,We establish the finite element models to analysis the dynamic and temperature stress response of pavement structure after using the LLMO and Synchronous Fiber Abrasion.The results show that the LLMO technology has better treatment effect for the asphalt pavement disease recurring.
