Study On The Rural Highway Cement Concrete Pavement Structure Of The Light Traffic

With the development of road enterprise and the concern of the Central Committee for the agriculture,countryside and farmers,there are more and more attention to the rural highway construction, especially to the poor areas,studying on the economic and practical cement concrete pavement reasonable structure of light traffic of the rural hianway has important significance.This paper shows the rural highway composition characteristics of the traffic volume based on the rural highway traffic survey, and analyses the axle load conversion of the rural highway traffic volume.Then it shows the common structure and material through surveying the present situation of the rural hianway cement concrete pavement,and lists the reference modulus of resilience of the common material, calculates and analyses the mechanics of surface plate thickness of different Climatic Zoning for Highway and pavement width of the rural hianway cement concrete pavement in the case of difderent traffic volume and pavement structure according to the"Specifications of Cement Concrete Pavement Design for Highway"and calculates the load stress under primary over loading by using finite element method.Also the paper recommends typical structure of the rural hianway cement concrete pavement,and analyses the economic benefit and social benefit of the typical structure,then puts forward the reasonability of typical structure in this paper.The study in this paper provides a reference for the cement concrete pavement design for light traffic of the rural hianway.
