Abstract: Old cement concrete pavement modified with asphalt surface, with its cost-effectiveness, is widely used in road upgrading project. This paper selects the typical "white to black" road reconstruction project, and uses a conventional pavement design software Southeastern University asphalt concrete pavement design sys-tem HPDS, to analysis and calculate the impact on the ｌｏａｄ stress of the thickness of asphalt overlay, the old concrete elastic modulus, equivalent modulus of elasticity of the original road base and the stress reduction factor of the joint of the old concrete face. At last, Concluding variation provide a theoretical basis for the "white to black" pavement design and construction. 

Keywords: Concrete pavement; Paving asphalt surface; Largest integrated ｌｏａｄ stress; Elastic modulus
