A Typical Rural Highway Pavement Applications Of Tai'an City

Taian City, more types of technical grade of rural roads, the disparity in construction technology, has no specific suitable environmental conditions and traffic conditions for rural roads of a typical pavement structure,no suitable quality control standards of materials for road construction and indicators. These have resulted in the adoption of standards for rural road construction is no scientific basis, a large gap between the level of road construction, road appeared earlier disease. In such cases, the research for rural road in Tai'an City, the typical surface structure, form a complete set of rural road pavement material, structure, construction technology, construction of rural roads to provide different levels of scientific criteria and selected on the basis of Tai'an City Shandong Province, as well as the construction of rural roads have unusual significance.In view of this article in our country under the guidance of road design, the first of Tai'an City investigation and analysis of highway traffic, divided the main diseases of highway Tai'an City case; After considering all aspects of the premise in Tai'an City, including the climate, soil, geology and hydrology of the road obtained the third rank division Tai'an City District, Tai'an City, the strength grades of rural highway roadbed; with local sources of construction materials, transport and economic development, construction and transport characteristics of the level of the development process in the region to adapt the structural standards of different road traffic conditions.On this basis, using the finite element analysis software ADINA examples of pavement structure finite element analysis, mechanical model, combined with the existing road design, road system, arrive at a more reasonable force process. With the asphalt pavement design parameters of Tai'an City in the rural areas the reference of the construction of rural roads in Tai'an City, experience and good methods of the pavement structure used by theoretical analysis, the final proposed typical asphalt pavement structure and construction quality control standards of rural road in Tai'an.
