| Highway as the aorta of China's road transport network,its commitment to the larger amount of transport tasks,so the need for better road performance.The development of expressway in our country has already entered the stage of construction,maintenance and management.The corresponding highway construction will be reduced,but the task of road maintenance will be increased.In this development situation,it is necessary to study the performance of the asphalt pavement material and the performance of the structure in the process.As a result of the many factors influencing the performance of the asphalt pavement of the expressway,the research on the performance evaluation of the asphalt pavement Is of great significance.This paper takes the highway section as an example,expounds the concept of expressway asphalt pavement performance,points out the selection and evaluation process of road surface performance and the factors that affect the performance of asphalt pavement.On this basis,Road conditions to analyze,according to a section of the general situation,the road conditions to investigate and test,get the appropriate test results.And then analyze the main diseases and causes of asphalt pavement in a certain section,the main sub-deformation disease,loose disease,crack disease and other diseases.Followed by the assessment of the use of asphalt pavement on a certain section of the expressway,including road damage,pavement bearing capacity,road surface quality,road safety performance and pavement comprehensive evaluation.According to the analysis of the previous parts of the highway section of the asphalt pavement remediation measures,mainly pavement disease remediation.The implementation of these remediation measures for improving the highway asphalt pavement performance,extend the service life of the road is of great significance.At the same time,for other highway asphalt pavement remediation program development,also has important reference value. |
