A crane mat is disclosed having a plurality of panels of lumber positioned in alternating transverse directions with respect to one another, where the top and bottom panels are oriented parallel to the direction of vehicular traffic. The top and bottom panels may include a plurality of spaced apart grooves extending longitudinally from a first longitudinal end of the crane mat to a second longitudinal end of the crane mat for enhancing traction of a vehicle when traversing across the crane mat by transporting rain or moisture off the mat, or for receiving mud or other debris. The crane mat may include a plurality of edge protectors positioned on respective sides of the crane mat to protect the crane mat from handling damage. In various embodiments, the crane mat may be manufactured using either softwood, hardwood, or any combination of softwood and hardwood.

A series of modules serve to provide a base for walkway members to be assembled into a walkway. Modules provide for support and orientation of walkway members and the ability to produce complex walkways with segments at varying orientations. In a preferred embodiment, a base mat is sized to engage walkway members. Using a combination of a number of base mats and walkway members, segments of walkway of any desired size can be readily assembled. Reflective and non-slip surfaces can be applied to increase safety when in use.

Disclosed are interlocking elongate composite bamboo industrial mats having an upper layer with two or more elongate laminated composite bamboo panels, an intermediate layer with a plurality of elongate laminated composite bamboo panels arranged in parallel and perpendicular to the laminated composite bamboo panels in the upper layer, and a bottom layer with a plurality of elongate laminated composite bamboo panels arranged in parallel to the upper layer. The three layers are secured together with fasteners consisting of a bolt, an outward-facing concave washer engaged with the bolt head, and a sleeve nut having an outward-facing washer engaged with the sleeve nut head. The interlocking elongate composite bamboo industrial mats are configured to interlock end-to-end or alternatively, side-to-side. Each of the elongate laminated composite bamboo panels comprises a plurality of kiln-dried glue-dipped elongate asymmetrically fractured bamboo strips compressed into a solid panel devoid of air spaces.
