The rural highway is an important national economic development, transport infrastructure , is an important part of China 's highway network , and is one of the most important infrastructure for the protection of social and economic development , is also one of the priorities of China 's highway construction . How to build good care of rural roads , improve the level of quality of construction and maintenance , to promote rural road construction , conservation , management standardization , scientific , and directly related to the realization of the grand goal of building a moderately prosperous society in Gansu Province , a vast , long and narrow , the territory of mountains criss-cross , altitude differences between dry climate changing . This unique geographical location , the geological environment in Gansu , hydro-climatic conditions , engineering and geotechnical distribution characteristics are very complex , in addition to Gansu Province weak rural road infrastructure , the construction of a shortage of funds , thereby increasing the rural road construction and maintenance management difficulty road early disease and sudden disasters , can easily result . Start from a rural road in Gansu Province disease investigation , summarized and analyzed , summed up the rural Gansu Province the highway roadbed typical disease roadbed Frothing , subsidence, collapse ( slide ) collapsed , gaps, landslides and water damage ; pavement typical disease mainly pit slot , loose , cracks Frothing and subsidence . Regional climate conditions , hydrogeologic characteristics , characteristics of natural zoning for highway and road disease extent through field research , analysis , systems analysis and research on the mechanism of the main diseases to make , and a set of disease prevention and treatment measures to Gansu Province, the design , construction and maintenance of rural roads to provide guidance . Papers based on the research results , through the analysis of the distribution and characteristics of the regional road construction materials , road materials options and special areas ( sections) subgrade engineering control measures recommended typical pavement structure in the form of the regional rural road , rural road works for the new the design and construction provide a technical reference . The paper analyzes the problems of the rural road maintenance management , rural road maintenance management countermeasures ; diseases typical of rural roads , rural road maintenance basic requirements , technology policy , quality requirements and roadbed , road , bridge and culvert conservation technical measures .
