Filed:

Jul 25, 2000

Appl. No.:

09/625495

Inventors:

Darrell Davis - Citronelle AL 36522
Ronald U. Davis - Citronelle AL 36522

International Classification:

E01C 908

US Classification:

404 35, 404 36, 238 14

Abstract:

A method and apparatus for constructing a temporary road bed include a mat formed from a plurality of planks having a longitudinal dimension and spaced-apart a uniform distance by a spacer. A flexible cable extends through apertures in the planks and spacers for coupling the planks and spacers together. The flexible cable allows the mat to bend and conform to the ground surface and can be rolled and folded upon itself. In one embodiment, the planks include at least one recess in a top face for interlocking with a plank of a second mat. The mats can be coupled together in an end-to-end relation to obtain a desired length or width or in a stacked relation to obtain a desired thickness of the road bed.
