Heavy Traffic Road Pavement Structure Optimization Study

This paper which analyzes the reason and mechanisms of destroyed heavy-duty traffic road surface carries out systematic research of materials, structural types and performance characteristics of it. First, aiming at the condition of typical heavy-duty traffic road in the whole nation especially in Jiaozuo,it carries out careful investigation and relatively systematic research for the destroyed road caused by heavy-duty traffic. HDS-2 movable axle is also used to make an experiment on the actual overloaded condition of existing road.for and pitch road surface of heavy duty, it conducts nonlinear experiment of half rigid material and heavy-duty ruts of pitch road surface. As a result, for the flexible structure of road surface, it aims up with corresponding optimum design methods and structural types of road surface.Through building experiment road, detailed observation of using effect as well as the comparison of technial economic effect, it achieves certain accomlishment which is significant of guiding structural design and construction of heavy-duty road in Jiaozuo and other areas.
