Abstract


With the high recognition degree of our nation and local government about rural area in recent years, the rural road which is one of the most important infrastructures that can promote economic development is paid more and more attention. Right now the Wuhan government accelerates the development of rural road and the condition is being improved. But because of the lack of founds and large scale, there are still many villages that don’t have rural roads.To reduce the cost of rural road construction and improve the fund utilizing efficiency, this paper aims at studying the combination and thickness of cement concrete pavement for rural roads in Wuhan which is low volume and light axle load. According to this, we can make a clear conclusion. Based on different functions of rural roads in the road network and its traffic characteristics, with different-standarded axle loads and experimental research, the paper has discussed whether the cement stabilized base, widely used in the rural road network, is suitable for the unfavorable drainage conditions. At the same time, employing the limited element software of ADINA and its theoretical methods, the paper has also analyzed what the least favorable blending and flexural stress, and temperature stress of the solid-cement mixtures base are. Those cement bases, used in the research, have different sizes, different thickness and under different axle load conditions. Though these ways, we hope to make an economic and practical road structure and work out perfect road thickness, which takes into account the characteristics of the rural road construction in Wuhan, and which can earn the most project benefit only with the least project investment. We also hope our research can provide ways to choose the best material which will be used in the construction of rural roads, and to design the most practical and profitable concrete road structure.
