Improved Beach Matting for U. S. Navy Amphibious Operations, Engineer Tests, January-August 1964

摘要

Engineer tests were conducted on three surfacing materials which were placed on an unsurfaced, sloped, sand test area to determine their suitability for improving the trafficability of sand dunes and beaches for wheeled vehicles. The test area was 100 ft long with a 10 percent slope. The materials tested were: (a) woven, 1-1/8-in.-square-mesh nylon netting, (b) woven, 4-in.square-mesh polypropylene cargo netting, and (c) woven wire steel mat. Each was subjected to the simulated traffic and estimated tonnage that would be unloaded from two landing ships, tank (LST's). The nylon netting was inadequate for the volume and tonnage of mixed vehicle traffic unloaded by two LST's, and the woven wire steel mat was too heavy for a crew of six men to place up the 10 percent slope of the test area. The cargo netting was adequate for all traffic and was considered the best of the materials tested. It was recommended that the cargo netting be modified to provide a faster method for connecting ends of sections for placement and to increase the width from 16 to 22 ft. (Author)
