Bridge approach slab is a concrete transitional roadway between the bridge deck and the asphalt pavement. (1) the required reinforcement ratio exceeds the allowed maximum reinforcement of flexure, i.e., > max = 0.75 b, meaning that section dimension needs to be increased. Approach slabs shown in plan view cases 1 and 2 represent a typical friction course 1.0 thick.
