Abstract: A temporary road mat configured as a timber mat including one or two layers of longitudinally oriented elongated timbers arranged in parallel at even intervals; one layer of transversally oriented elongated timbers arranged in parallel at even intervals and perpendicular to the longitudinally oriented elongated timbers; at least one membrane extending over an entire main surface of the timber mat, wherein the timbers are drilled and bolted together at intersections.

Abstract: An apparatus for producing timber mats including plural layers of timbers that are parallel to each other and offset from each another at uniform intervals, wherein timbers in adjacent layers are oriented perpendicular to one another forming an array of intersections spaced in longitudinal columns and lateral rows, the apparatus comprising a timber mat layup table; a first lateral timber input oriented in a first direction and arranged at a first side of the timber mat layup table; a second lateral timber input oriented in a second direction opposite, coaxial and parallel to the first direction and arranged at a second side of the timber mat layup table opposite to the first side of the timber mat layup table; a longitudinal timber input oriented in a third direction perpendicular to the first direction and the second direction and arranged at a third side of the timber mat layup table.
