Study And Application Of Highway Maintenance Management System

This paper studies the development situation of domestic and foreign highwaymaintenance system, Discussion the highway management mode and characteristics,and analysis the defects in our country highway maintenance system. Highway is theinfrastructure construction in China, but the overall maintenance personnel quality isnot high,and the lack of professional maintenance knowledge, So far it has no unifiednational standards of Maintenance and technical standards, maintenance machinery andequipment is relatively backward. For the defects of our country’s maintenance system,we can learn something from foreign about advanced maintenance technology andmanagement mode, combined with the specific circumstances and characteristics ofhighway in our country, puts forward corresponding method. At the same time to speedup the construction of maintenance system, improve the mechanical maintenanceequipment level, combined with the Professional technical people, and use the advancedtechnology and equipment, make the maintenance experience as reference, develop newmaintenance technology.Establish database in the center of expressway maintenance management system,And the scope of management system is divided into project management and networkmanagement system, Unified management of the basic data of pavement, such as thewidth of the road, the number of lanes and pavement condition data such as pavementanti slide performance, service, disease index and so on. Data automation monitoring,make the contemporary Highway information and modern scientific managementtogether. Through use this modern database platform, we can timely understand andmaster the expressway operation conditions and Pavement damage degree.Analysis the causes of highway diseases in different structural features such as pits,rutting, cracking, frost boil, And make the asphalt concrete and cement concrete of thetwo main type of pavement for example, Put forward the solution of pavement diseases,illustrates the importance of road maintenance work. And puts forward the point ofpreventive maintenance, carries on the real-time monitoring to the pavement,According to the cracks, pavement settlement and other various diseases, use the filling,cover and other measures, timely control the spread of pavement diseases,Toimplement the "prevention first, combining prevention with control" policy, Throughthe comparison of the preventive maintenance and overhaul maintenance’s economicbenefit and social benefit, emphasized the importance of preventive maintenance ofpavement. This paper takes hubei province Hanshi highway for example, Focus on study theHanshi highway pavement structure, climate, transportation, engineering andExpressway Pavement performance index such as pavement roughness, skid resistance,deflection index, According to the influence factors of the pavement, analysis pavementmaintenance and repair’s costs, emphasizing the economic benefits of highwaymaintenance, and puts forward the model of maintenance system of sustainabledevelopment. Simulate and evaluate the pavement performance and damage Structural,Combined with the needs of maintenance of pavement, Combined with the needs ofmaintenance, pavement analysis and maintenance cost’s allocation, to help expresswaymaintenance management system of highway provide the most scientific, effectivemaintenance decision, Provide the most scientific, effective basis for maintenancedecision of expressway maintenance management system of highway, to have moreroom for development. Make the maintenance management system of highway havemore development space.
