Research On Performance Evaluation And Maintenance Countermeasures Of Highway Asphalt Pavement In Shaanxi Province

With the completion of the construction of highway network in China,the development center of highway has gradually transited from construction to maintenance.As the main part of highway,the quality of pavement and the severity of disease are related to the safety of driving.With the effect of driving load and the influence of natural factors,various kinds of serious or light diseases will appear in the process of road operation,which has caused great safety hidden dangers to the road operation.With the rapid development of social economy,the traffic transportation industry becomes increasingly busy,which also makes the road disease of operation become increasingly prominent.Therefore,it is of great significance to strengthen the detection and evaluation of highway pavement to improve highway performance and prolong highway service life.This paper first classifies and analyzes the main types and causes of road pavement,and investigates the typical typical pavement diseases and distribution characteristics in Shaanxi Province.Secondly,it comprehensively summarizes the pavement disease detection technology and expounds the rapid detection of pavement evaluation indicators.Theoretical basis,test methods that can be adopted;again,according to the characteristics of highway maintenance management in Shaanxi Province,based on the current pavement performance evaluation system and evaluation method,the indicators and evaluation criteria of pavement disease evaluation,introduce the performance evaluation of Shaanxi pavement The preliminary application practice of the analysis,finally,based on the years of road maintenance management experience in Shaanxi Province,through the analysis of the main factors affecting the maintenance countermeasures,summed up the province's disposal measures for the maintenance of asphalt pavement disease maintenance,medium repair,preventive maintenance,and In-depth discussion on the establishment of a road maintenance strategy tree under the consideration of regional differences,traffic volume,and priority levels of road indicators.
