International Classification:

E01C 500

US Classification:

404 35, 4034081

Abstract:

Multipurpose panels having L-shaped tabs are interconnected using durable connectors to form a multipurpose mat that facilitates mobility over otherwise unstable terrain. In one embodiment, four-sided panels are fabricated from laminations of fiberglass-reinforced plastic (FRP) with radiused rectangular holes machined in each of two adjacent edges and a recessed L-shaped tab formed along opposing adjacent edges. The connectors are fabricated from corrosion resistant metal and assembled to precise specifications prior to insertion in the rectangular holes machined in pre-specified types of panel. Top and bottom plates of durable connectors are fabricated from 6061-T6 aluminum stock. A threaded bolt used to tie the plates together, to which a liquid threadlocker is applied, is fabricated from a steel alloy suitable for use with aluminum. Two specially fabricated tools, a spacer guide and an alignment tool, may be used to optimize installation. These also may be fabricated from 6061-T6 aluminum stock.

Abstract:

A grid system for stabilizing an underlayer and providing a support surface ncludes 60 longitudinally extending polyethylene strips which are bonded one to another in an offset manner and are adapted for providing a grid. The grid has a first collapsed orientation wherein the strips are generally linearly aligned and substantially contiguous and a second expanded orientation wherein the strips are generally longitudinally sinusoidal for providing a plurality of cells. The cells are filled with compacted naturally occurring beach sand. An asphalt layer is applied to the upper surface of the grid and penetrates the cells to a predetermined depth for thereby providing a roadway surface adapted for vehicler traffic.

US Classification:

Abstract:

The invention is a dynamic cone penetrometer for measuring soil shear strength which includes an elongated cylindrical rod having a tip end and a handle end. An anvil portion is mounted to the rod at a selected distance from the handle and a penetrometer tip having a conical free end is secured to the tip end of the rod for engaging the soil or sample. A two weight drop hammer having a cylindrical through bore is slidably mountable on the rod at the handle end for striking the anvil with a selected force when released from a fixed distance from said anvil. The drop hammer is formed in two parts including a cylindrical core portion of a first diameter, and a cylindrical support portion extending from the core portion to a second diameter. The second weight has a through bore and is sleevable over the core for engaging and resting upon the support portion. A releasable fastener secures the second weight to the core so that proper measurements may be performed with the first weight alone for weak soils or with both weights for stronger soils and surfaces.
