Abstract
A three-dimensional frame structure for the construction of road mats is disclosed. The structure includes the components of the mat positioned to insure uniformity of assembly of mats of different sizes, with a single end structure that acts as a template and with means for moving a mat for final affixing onto a table while permitting the assembly holding structure to be repositioned for constructing another mat. A method of manufacture for road mats which utilizes a frame to position the components of the mat during the mat's manufacture into a predetermined arrangement to ensure the uniformity of each mat for interchange use in the field is also disclosed, whereby mats may be completed by the apparatus while other mats are being assembled. A temporary road comprised of two sets of mats is also disclosed. The first set of mats is laid down such that its smooth surface is on the ground. A second set of mats is interlaced so that each mat of the second set overlays one-half of two adjacent mats of the first set or, alternatively, overlays four mutually touching first set of mats. Channels and corresponding transverse elements are provided in both the first and second set of mats to permit the overlap by approximately one-half of a mat of the first set with mats of the second set.
