Abstract: A method of making a modular engineered wood composite road (40) includes determining a bearing strength of the soil at a location where the modular engineered wood composite road will be installed; determining a bearing strength of the soil at a location where a modular engineered wood composite road (40) will be installed; determining a flexural strength and stiffness required for the modular engineered wood composite road (40) based on the determined bearing strength of the soil at the location where the modular engineered wood composite road (40) will be installed; assembling a plurality of engineered wood composite billets (46) from a plurality of composite wood laminations, wherein each engineered wood composite billet (46) has the required flexural strength and stiffness; and assembling the engineered wood composite billets (46) to define the modular engineered wood composite road (40).

Abstract: A support mat includes a plurality of vertically oriented individual wood members adhesively bonded to each other, each of the individual wood members having wide faces oriented parallel to a direction of a load applied to the support mat, the support mat having outboard wood members, the outwardly facing wide faces of the outboard wood members defining a wide face of the support mat. The support mat also includes least two protective edge members, each protective edge member having an inboard wide face, each of the at least two protective edge members positioned against one the wide faces of the support mat. At least two substantially rigid fasteners extend through and connect each of the protective edge members and adjacent wood members. The wood members, protective edge members, and fasteners define a substantially rigid support mat having a substantially planar wide face.

Abstract: A support mat, such as a mat suitable for supporting heavy construction equipment, includes a plurality of billets fastened together, each of the billets being made of a plurality of individual wood laminations adhesively bonded to each other. The billets comprise a plurality of vertically oriented individual wood laminations. The plurality of individual wood laminations has wide faces oriented parallel to a direction of a load applied to the support mat. Each billet has outboard laminations and the wide faces of the outboard laminations of each billet define a wide face of the billet. An expansion pad is disposed between the wide faces of adjacent billets.
