The Typical Structure Of Asphalt Pavement In Xinjiang

Good or bad road conditions will directly affect on traffic comfort and safety. The rational design of pavement structure is a prerequisite for ensuring to drive safely and server economic construction effectively. Currently, we have more complete theoretical methods of asphalt pavement structural design, which mainly have solved the thickness computational problem of the pavement structure, and given more guiding suggestions for structural combinations, material selection and composition requirements. However, in practical engineering design, we should design pavement construction specifically according to the local traffic conditions material sources and natural conditions.how to design pavement construction rationally and specifically, according to the different climates, geological conditions and material sources of the site locations, has become very important.This paper relies on the research of Asphalt Pavement Design and Construction Guide items for Xinjiang, it mainly systematic analysis from asphalt pavement structure, types of diseases and causes of the traffic survey and grading, and asphalt pavement layer parameters effect the thickness. Through investigation and test data, statistical analysis the Asphalt Pavement damage, and evaluate the existing asphalt pavement type; on the base of traffic flow surveys and order, it given the traffic volume graded on Highway. Through analysis the affection that the asphalt pavements design parameters affection on the road typical thickness, to obtained the relationship of the structural layer parameters and the road thickness. At last, considering climatic zoning, discussion on the different road grades under all load types, recommended the typical asphalt pavement structure type.In a short, to carry out study on the typical asphalt pavement structure for Xinjiang, finally, it will be effective provide scientific guidance for the design and construction units.
