1. A load supporting structure comprising:
- a. a first generally rectangular panel having a top, a bottom, a plurality of substantially vertical walls extending between said top and bottom which define a plurality of hollow cells, and a substantially solid lip along two adjacent sides of said panel, wherein a skin is disposed along the bottom of said substantially vertical walls to define a substantially continuous surface on the bottom of said first panel;
b. a second generally rectangular panel having a top, a bottom, a plurality of substantially vertical walls extending between said top and bottom which define a plurality of hollow cells, and a substantially solid lip along two adjacent sides of said panel, wherein a skin is disposed along the top of said substantially vertical walls to define a substantially continuous surface on the top of said second panel;
c. a plurality of raised elements extending from the lower surface of said first panel, wherein said raised elements are proximate to and in general alignment with the vertical walls of said first panel;
d. a plurality of raised elements extending from the upper surface of said second panel, wherein said raised elements are proximate to and in general alignment with the vertical walls of said second panel; and
e. means for affixing the top of said first panel to the bottom of said second panel, wherein said panels are offset relative to one another such that said substantially solid lip of said first panel forms a lower peripheral extension along two adjacent sides, and said substantially solid lip of said second panel forms an upper peripheral extension along the remaining two sides, and the substantially vertical walls of said first panel are aligned with said substantially vertical walls of said second panel.

Abstract
A reusable mat system for the construction of load bearing surfaces, such as temporary roadways and equipment support surfaces, over unstable or unsubstantial terrain, comprising durable, interlocking individual mats which can be quickly and easily installed in a single application, and which can thereafter be easily removed and stored until needed again. The individual mats of the present invention interlock on all sides to form stable and continuous load bearing surfaces, and exhibit favorable traction characteristics.
