The Application Research Of Asphalt Pavement Preventive Maintenance In Xin Jiang Highway Maintenance Practices

With the development of the road network, the road maintenance tasks increasing, add a limited number of maintenance funds, the traditional road maintenance methods cannot meet the needs of the highway maintenance, the urgent need for a new road maintenance method or technique to improve the efficiency and effectiveness of road maintenance, preventive maintenance can help it.To facilitate Asphalt Pavement Preventive Maintenance Technology in Xinjiang highway maintenance practice. The first part, from the domestic and foreign research point of view of preventive maintenance of asphalt pavement were reviewed for this study; The second part, a detailed explanation of the theory of preventive maintenance, such as preventive maintenance definition, connotation and denotation, the decision of asphalt pavement preventive maintenance, and general technical measures; The third part, analysis the need for preventive maintenance in use of the asphalt pavement in Xinjiang,analyze the kinds of roads in Xinjiang region, and characteristics or distribution of conservation, and diseases Causes; The fourth part, based on the conservation status of application of asphalt pavement preventive analysis on Xinjiang,S210 line surface crack sealing stitch preventive maintenance project as an example, the system introduces the asphalt pavement preventive maintenance application in Xinjiang highway maintenance practice, and to project the effect of a comprehensive evaluation; The fifth part, proposed effective prevention Xinjiang asphalt pavement application of conservation proposals and safeguards.After S210 Line Sealing surface cracks in preventive conservation projects confirmed Asphalt Pavement Preventive Maintenance Technology in Xinjiang highway maintenance practice it is feasible and also effective. Asphalt pavement preventive maintenance to improve road maintenance work results Xinjiang, the Xinjiang region to extend the life of roads,highways further reduce maintenance costs and improve the life cycle of road transportation capacity has important significance.Attention: To ensure Xinjiang highway asphalt pavement preventive maintenance work results, we need to accurately grasp the opportunity to carry out preventive maintenance.
