Investigation Of Cement Concrete Pavement Maintenance Mode And Effects Of Guangdong Province

During the "Eleventh F ive-Year", the count ry has carried out a lot of Guangdong highway maintenance and repair work, has accumulated a wealth of successful ex perience, urgent application in national and provincial levels trunk road maintenance and reconstruction of the county. Into the " Twelve Five-Year", resource-saving and environment-friendly society to be placed in m ore and m ore prominent position, the fuel tax reform, transform ation of government functions also for highway m aintenance management put forward higher requirements. How in the new developments, the full summary of past successful experience, further enhance the level of m anagement of road maintenance, road maintenance accelerate scientific realization, standa rdization, Guangdong Province has become an im portant task facing the road sector at all levels. In this context, the Guangdong Provincial Communications Department and the Provincial Highway Aut hority to carry out the project "G uangdong Highway Maintenance typical pavem ent structure to prom ote applied research" project, I participated in the research of this subject, is m ainly responsible for Cement Concrete Pavement maintenance mode and effects Research.The project study for Guangdong Province ordi nary trunk roads. Research objectives through existing national and provincial Guangdong province, research, testing, review, and research in the application of road m aintenance and technology demonstration project, on the old road testing and evaluation of highway maintenance, preventive maintenance technology(Preventive Maintenance question the tim ing, measures, materials and process requirem ents, quality evaluation), overhaul pavement structur e and material durability design, construction quality control, perform ance monitoring syst em and other research studies, eventually forming the Guangdong Provincial Highway Ma intenance typical P avement design and Construction of complete sets of technology to im prove pavement performance, reduce early Guangdong national Highway road damage and prolong life.Through investigation, evaluate the effect of the application m aintenance and repair programs for the enviro nment typical summary conservatio n programs. Ultimately, basic grasp of the pavem ent structure and m aterial of national and provincial roads preventive maintenance, overhaul conservation practical ef fect during use, and local weath er, traffic environment, geology adaptability.
