The Study On The Wheel Track Slab Reasonable Dimension

The wheel track road refers to the roadbed width range, the formation of pavement materials in traffic load frequency effect of wheel track paved with a certain thickness and width of the road. This road structure is suitable for the light traffic, its characteristics are small hardened area, less environmental damage, good durability, convenient maintenance, less investment. In foreign countries, the wheel track road early application, but it is still no design theory and method of special. In order to study more in line with actual wheel track road work, this paper choose the village road as research subjects in Manhui town, Bayannaoer city, Inner Mongolia Autonomous. Investigation on the road traffic over a long period of time, the transportation infrastructure data and a large light traffic area. Possession and use of survey data combined with Cement Concrete Pavement Design Specification JTG D40-2011on the wheel track pavement reasonable depth study of geometry by the line.Firstly, the wheel tracks pavement belongs X (aspect ratio)greater narrow strip, it’s easy to be flapped under partial loads prone, Against the unique failure modes of wheel track road, researched on the overturning issues of wheel track pavement and proposed a reasonable plate width design.Secondly, by reading a lot of literature on the wheel tracks and ultra-thin concrete roads, affecting the wheel tracks pavement stress distribution and conduction of the main factors were screened using ABAQUS finite element software analyzes each factor screening finite element, draw the conclusion that the relationship between each factor and pavement load stress, as well as the combined effects of multiple factors and pavement stresses.Thirdly, on the basic of the existing roads design and full pavement material properties proposed a reasonable wheel track pavement geometry.
