Abstract: A noise barrier pad and a method for the production of same comprises the steps of forming a tread layer by reacting a mixture for polyurethane foam in a hollow mold having separable upper and lower parts and which is shaped so as to form the tread layer, curing the foam, removing the upper part of the mold, placing a blank of noise barrier material on the surface of the foam which corresponds to the bottom side of the tread layer, and forming a bottom foam layer on the tread layer and barrier material by placing another upper mold constructed in accordance with the bottom layer of the noise barrier pad and defining a cavity over the tread layer and barrier material and filling the cavity with the reaction mixture for the polyurethane foam.
