Research On Repairment And Maintenance Management Of High-grade Cement Concrete Pavement Technologies

Under guidance of the transportation infrastructure construction policy in our country, the transportation industry developes fastly in China. Cement concrete pavement with high strength and high, good stability, good durability, low cost advantage is promoted and used, but with the development of national economy, the increasing traffic volume, the overload, the emergence of the problem such as traffic channelization accelerates the damage of cement concrete pavement. The destruction of the cement concrete pavement has brought great economic losses of our country, how to do the cement concrete pavement maintenance and maintenance management work is of important significance to save resources. The research object of this article is a high-grade cement concrete pavement, mainly studying the key technology and maintenance management maintenance.Firstly,it analyses the background and significance of this article by analyzing the current development of repair materials and fast repair technology at home and abroad, puts forward the our country on the rapid repair materials and the construction of repaired the existing problems, expounds the research content and technical route.Secondly.it analyses the main diseases of cement concrete pavement by Guangdong province more high-grade cement concrete pavement,such as crack, crushing plate, fracture voids, chew. Those diseases are caused of these mainly basic reasonable, such as pavement thickness, imperfect drainage system design, unreasonable distribution, construction and maintenance aspects, used too long, etc. Then analyzes the cement concrete pavement maintenance materials and the kinds of choices, and analyzes the cracks in cement concrete pavement for Guangdong rapid repairing materials. On the basis of the analysis of the reasons for damage of the cement concrete pavement and types, and expounds the pavement damage condition evaluation and the ride quality evaluation theory method.The third part analyses the types of cement concrete pavement repairment materials. On the basis of analysis, it analyzes the causes and types of cement concrete pavement damage. Then it studies the high-grade cement concrete pavement repairmen methods, firstly studing the "Highway Cement Concrete Pavement Maintenance Technical Specifications" for minor cracks, crack moderate, severe crack repairment methods commonly used treatment, maintenance technicians analyzing the seams, crack repair technology, road blocks fast repair technology three technologies, namely the cause, construction technology, repairment methods, construction equipment and other aspects of performance requirements from the cracks to explore the use of technology categories. Then it puts the high-grade cement concrete pavement maintenance management, through the analysis of high-grade cement concrete pavement maintenance management features, content, maintenance standards, the problems presentes the final work of conservation management.The fourth part mainly from high-grade cement concrete pavement condition investigation and analysis to study, the first is to discuss the train of studying the pavement evaluation index, from a single aspect reflect accurately the road conditions. Then solved by constructing a model, and puts forward some pavement condition evaluation index to fully consider comprehensively.Finally, the article analyzes SHENSHAN EAST highway case. According to the test before the engineering investigation and analysis of data for evaluating pavement condition, and according to the bar and select grouting stabilizing board crack, crack repair method for pavement maintenance works. These research work for repair and maintenance work of cement concrete pavement in China will have a certain reference and application value.
