By applying the theory of structure elasticity,this paper first gives an account of the function of the cement concrete bridge deck pavement, then simplifies the forces on the pavement and finally makes some hypothesis according to the realistic conditions. A design method is presented on the basis of the maximum moment of the force on the whole bridge and with the crack and fracture of cement concrete bridge deck pavement as the controlling index. An example and range of suitable use are also given in the paper.
