ABSTRACT:
A light weight pavement module is described which comprises a base grating, an impervious intermediate layer, such as a reinforced plastic or fiberglass sheet applied over the base grating, and a concrete top layer wear surface applied over the intermediate layer. The intermediate layer prevents the concrete top layer from penetrating through the base grating. The grating has shear connectors which pierce the intermediate layer and project into the top layer wear surface in order to form an integral pavement module. The pavement module may be formed without an intermediate layer if the module is otherwise constructed so that the top layer wear surface does not penetrate and fill the interstices of the base grating.
