Abstract: A roadway/platform mat construction is provided for disposition over soft ground. The mat construction includes a rectangular, panel-like mat structure including opposite transverse end margins and opposite side longitudinal margins. The mat construction defines a first rectangular surface and a second rectangular surface facing opposite and paralleling the first surface and including elongated transverse members carried by the opposite ends of the mat structure and projecting outwardly of the second surface thereof. The transverse members are of a length measured longitudinally of the mat construction equal to substantially one-quarter the length of the overall mat structure and the spacing between opposite end members of each mat structure measured longitudinally thereof is equal to substantially one-half the length of the mat structure.

Abstract: A roadway/platform mat construction is provided for disposition over soft ground. The mat construction includes a rectangular, panel-like mat structure including opposite transverse end margins and opposite side longitudinal margins. The mat construction defines a first rectangular surface and a second rectangular surface facing opposite and paralleling the first surface and including elongated transverse log structures carried by the opposite ends of the mat structure and projecting outwardly of the second surface thereof. The transverse logs are of a width measured longitudinally of the mat construction equal to substantially one-quarter the length of the mat construction and the spacing between opposite end logs of each mat construction measured longitudinally thereof is equal to substantially one-half the length of the mat construction.
