Title: Mechanical Analysis of Cement Concrete Overlay on Asphalt Pavement
Abstract: As a new,effective,rapid,cost-effective and simple maintenance of the old asphalt pavement technology,cement concrete overlay although has done a great deal of testing on road in the United States,about the road stress analysis is still very small.Large-scale finite element analysis software ANSYS has been used in building 3D structural model to make mechanical analysis about the cement overlay on old asphalt pavement.Analyses:load function sturcture layers of elastic mould amount and change of thicness add and pave influencing by strength of layer to the road surface vehicle through finit element;thermal stress and temperature and coupling which the vehicle load under temperature function;the impact bring by repairing and the cracks on the old road to the load stress analysis.It gives some suggestiong to the design of cement concrete overlay.
