Abstract
Based on analysis the causes of concrete face slab cracks
according to the elastic force scientific theory and the structure analysis to propose the Two-layered slab structure combined by asphalt concrete face slab and the plain concrete face slab.This method releases the distorts and the restraint
reduces the concrete face slab tensile stress
realizes the division function of the slab anti-crack and the anti-seepage.The theoretical analysis and the value computation confirms the measure feasibility.
