Research Of Low Grade Highway Asalpht Pavement Typical Structure

Highway construction in our country is full of vitality and semi-rigid roadbase asphalt pavement has become a major type of pavement structure of county road in recent years.Enormous numbers of material and money have been wasted for the conservation of pavement design or the roads could only be used few years for some designer only know little about rigid-roadbase asphalt pavement.So typical or standard pavement structures are need exactly now to eliminate the random by the way of selecting these structures.hi this paper, a set of typical pavement structures is given and some problems have been solved. The first step is present the computation and dividing methods of roadbase back module and cumulatetion of axle load, which are two major reasons of affecting pavement structure design.Attitude math module has been given emphasis when value the property of pavement. At the same time, the parameter of pavement design of low grade highway has been presented considering the experience of local pavement design. At last the type of pavement structures are given out and application program is written for designer to use.
