ABSTRACT:
A grid system for stabilizing an underlayer and providing a support surface ncludes 60 longitudinally extending polyethylene strips which are bonded one to another in an offset manner and are adapted for providing a grid. The grid has a first collapsed orientation wherein the strips are generally linearly aligned and substantially contiguous and a second expanded orientation wherein the strips are generally longitudinally sinusoidal for providing a plurality of cells. The cells are filled with compacted naturally occurring beach sand. An asphalt layer is applied to the upper surface of the grid and penetrates the cells to a predetermined depth for thereby providing a roadway surface adapted for vehicler traffic.
