Stresses in Concrete Road Slabs

Although at first sight the design of a concrete road slab may appear to be one of the simplest of engineering problems, it is, in fact, extremely difficult and complex. Even after many years' research both in this country and abroad there is still insufficient information available to enable the design to proceed in the usual manner for engineering structures, namely, on the basis of an adequate knowledge of the maximum stresses to which the road slab will be subjected. Important factors in the problem are the loads imposed by traffic, temperature and moisture changes, and the supporting conditions supplied by the subgrade and the adjoining slabs. F.N. Sparkes
