Analysis Of Asphalt Pavement Disease And Reconstruction Project Of Trunk Highway In Jinzhong

With the rapid development of coal industry in Shanxi Province a few years ago,the traffic volume showed a trend of rapid growth,the vehicle was shown to be large and heavy,Especially the overloading of transportation becoming more and more serious,and also affected by the environment,climate,structural design and other factors,it was unavoidable to be various diseases in the weak pavement of trunk highway in shanxi.The emergence of these diseases seriously reduced the service functions and service life of pavement,and badly influenced the normal operation of the highway.Based on the trunk highway in Jinzhong,the cause of asphalt pavement disease was analyzed and summarized,and the pavement reconstruction project was studied in this paper.It selected two typical disease sections from the trunk highway in Jinzhong,The evaluations of this sections were carried out through detection and data analysis.The main cause of the disease was analyzed,and the causes and influencing factors of the disease in the weak section were analyzed in detail from the aspects of cracks,rutting and water damage.It also pointed out the relevant measures that can effectively prevent the pavement from causing disease in this paper.Then the economics of Jinzong and the related counties were investigated and analyzedon on the background of the economic status of Jinzhong,and the linear model and second-degree parabola model were used to predict the regional economic development.On the basis of this,it set up a regression model which was used to carry out trend epitaxy and find out the regional distance traffic according to the strong correlation between goss national product and traffic demand.In the end of the paper the road reconstruction plan is put forward according to certain standard and treatment principle,at the same time,the rationalization proposal and construction organization plan are given for the successful implementation of the projectIn this paper,it provides a theoretical basis for the feasibility of asphalt pavement repairing of trunk highway in Jinzhong through the study of the main relevant theories.These models and methods which used have high theoretical and practical value.Tt demonstrates the necessity of engineering construction,the rationality of repairing plan,the feasibility of technology and the the possibility of implementation,which provides a scientific basis for project decision.
