  • Temporary road bed
    Patent number: 6874972
    Abstract: An 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.
