The Typical Structure Of Linear Index And Pavement Of Rural Road In Wushan County

At present, Wushan County Rural Road technology level is low, the ruralhighway development lags behind, which seriously restrict the development of the localeconomy and society, in order to better guide the rural highway construction in WushanCounty, this paper systematically studied on the technical standard of highwayalignment and the typical pavement structure in rural areas of Wushan county.This article through to the Wushan County topography, climate, soil,geological condition, road condition, traffic volume and traffic composition of lots ofinvestigation, analyses the existing problems of rural highway in Wushan County,provide a basis for the establishment of Wushan county rural highway alignment indexand typical pavement structure. Through the research and Analysis on the existing formof rural Wushan county highway traffic volume and traffic volume, Wushan CountyRural road grade and traffic design parameters are determined, and according tospecification, the technical index of each grade line Wushan County Rural highway. Inaddition, the road condition and road in Wushan county were investigated withreference materials at home and abroad, the design method of pavement structure,combined with the actual situation in Wushan County Rural road pavement structuredesign principles and experience, and ecommend the rural highway asphalt, suitable fordifferent traffic grade cement typical road surface structure. Finally, Analysis of cementboards of different sizes, different thickness, different axle load under the conditions ofthe bottom most unfavorable flexural tensile stress and temperature stress by using theABAQUS finite element software and theory method. In order to determine theeconomic and reasonable, feasible technology of pavement structure and surface layerthickness. At the same time, using ABAQUS simulation analysis of asphalt pavementstructure with different thickness of asphalt pavement, the typical form of rural roads inWushan county was determined.The research results of this paper has strong pertinence, reasonable and reliable,economic use, has very important reference value for the construction of WushanCounty Rural highway.
