Structure Research Of Typical Rural Road Pavement In Taian

The main features of rural highway traffic volume is generally small, mostly agricultural load lighter vehicles, tractors or motorcycles, the existing national norms, the level of the road is too broad range of design parameters, in the implementation of the practical applications around the specification provided only rely on the design principles and design parameters of the range to be selected, with great arbitrariness and uncertainty. With the rapid development of China's national economy and state policy changes in rural road construction, the whole country to speed up the construction of national highways at the same time, the technical standards for rural roads and road use of a higher quality requirements.This paper studies the content of Taian city by road traffic in rural areas to investigate and gather relevant information, analyze the composition of the rural road traffic, the use of BP neural network to forecast future traffic. Traffic parameters of pavement structural design in one of the important design parameters, the direct impact of traffic classification of the pavement structure and thickness determination. Taian City, according to survey results and a local foundation material sources of local materials, the situation in the region through field experiments to determine the type commonly used in roadbed material and the use of performance and to determine the design parameters of various road materials, which are typical of rural road Taian city pavement. Finally, the actual situation in Tai'an, in highway construction specifications as the basis, considering the road's economic performance, performance factors, such as highway pavement road construction technology and quality control.
