Research On Detection Evaluation And Maintenance Treatment Of Municipal Road Pavement Diseases

The construction of municipal roads is always extended with the development of urbanization process,and the process of urbanization in China is now improving,and most of the municipal facilities are in an old state.The good operation of municipal roads is a prerequisite to protect the public travel,but the old municipal roads have different degrees of pavement diseases.Pavement structure layer is an important part of municipal road,pavement diseases seriously hinder the normal traffic function of the road.Therefore,it is particularly important to use scientific methods to detect the pavement performance,study the formation mechanism of diseases,and put forward reasonable treatment scheme through research and comparison.First of all,it is necessary to detect the pavement diseases of municipal roads.By analyzing the types,methods and principles of pavement disease detection,the advantages and disadvantages of various detection methods are compared.At the same time,combined with the current situation of pavement disease detection in Xi’an,the suitable method for the detection of pavement diseases in this region is selected,and the suggestions for improvement and perfection of the current situation of pavement disease detection in this region are put forward.Secondly,after the completion of pavement disease detection,the main types of pavement diseases in this area are screened out,and the main types of pavement diseases are taken as the focus of later detection.Combined with the characteristics of pavement diseases in this region,the paper analyzes the causes of the main types of pavement diseases,and puts forward countermeasures for the causes of various diseases.Thirdly,the degree of pavement disease is evaluated from the overall performance and individual performance of each classification,so as to make a relatively comprehensive evaluation of pavement disease.Through the evaluation of pavement disease in Xi’an area,the main performance indexes of pavement disease evaluation in this area are optimized and analyzed emphatically in the later pavement disease evaluation.Finally,combined with the engineering practice of pavement disease treatment in Xi’an area,through the detection of pavement diseases,the main types of diseases are summarized and the causes are analyzed.Based on the evaluation of pavement disease damage,several maintenance and treatment schemes are put forward.Combined with the actual project effect and project cost,the paper makes a comprehensive comparison of several schemes,finds out the shortcomings,and optimizes and improves the scheme in the later stage,so as to provide reference for similar projects.
