Abstract
An interlocking wooden mat assembly for roadways in undeveloped areas comprises a three layered lamination of substantially parallel and closely spaced wooden planks forming each layer, which assemblies are rectangular and interlock along one of the longer sides. Selected planks of the bottom layer are offset longitudinally and extend beyond the intermediate layer at one end to provide a male extension on one end and a female recess at the other end. The planks of the bottom layer lie parallel to each other along the shorter dimension of the rectangular mat. The planks of the intermediate lie parallel to each other along the longer dimension of the rectangular mat and terminate at the edges of the rectangle. The top layer has planks extending parallel to each other and to the bottom planks along the shorter dimension of the rectangle comprising two groups of planks spaced toward the edges of the rectangle with the intermediate portion of the intermediate layer of planks being uncovered. The two groups of planks in the top layer are separated sufficiently to provide spaced tracks for the tires of a truck of other motor vehicle riding thereon, each group having a centrally located space wide enough to receive another plank of the same size. Extra planks are secured in those centrally located spaced and overlapping adjacent mat assemblies to secure such assemblies together as a roadway. Each mat assembly may have loops of cable for lifting and transporting.
