ABSTRACT:
An apparatus and method for constructing a reusable wooden matting system for use as a temporary surface at construction sites. The matting system includes interlocking mats of four differing configurations. Each mat configuration consists of wooden boards fastened together to create from one to three layers of boards at various areas of the individual mats. When interlockingly installed a desired area is uniformly covered with three layers of boards. The upper, working layer of boards, bears the vehicular traffic or equipment placement. The middle, intermediate layer of boards, consists of interlock boards which fittingly interlock with corresponding spaces of adjacent mats, and, interspace boards to reinforce the weight bearing characteristics of the mats. The lower, contact layer of boards, rest upon the terrain. Within a layer the boards are parallel to one another, whereas the boards of each layer are perpendicular to the boards of any adjacent layer. When installed each mat interlockingly overlaps or underlaps approximately one-third of the width and one-half of the length of laterally adjacent mats. Both lateral and longitudinal relative movement of any installed mat is substantially precluded by a portion of each mat unit being in frictional engagement with the terrain, by a portion of each mat unit overlapping interlocking with adjacent mats and all three layers of each mat laterally and longitudinally abutting other mats which are also in frictional engagement with the ground.
