Expedient Surfacing and Drainage of Roads, Streets, and Parking and Storage Areas in Theater of Operations. Report 2. Tests Conducted Between August 1968 and July 1969,
Abstract
Engineering tests were conducted on a test road covered with an asphalt-impregnated polypropylene membrane to determine the effectiveness of the combined materials as a dustproof, waterproof wearing surface over adequate-strength subgrades and as an encasing membrane used to form a membrane- enveloped soil layer (MESL) in areas where high water tables exist. The polypropylene- asphalt membrane was installed on the test road, exposed to varying climatological conditions prevalent in the Vicksburg area, and subjected to mixed pneumatic-tired traffic of military vehicles. Vehicles used for testing were a 2-1/2 ton, 6 x 6 cargo or dump truck and a 5-ton, 6 x 6 cargo or dump truck, both carrying maximum off-highway loads and having appropriate tire pressures. It was concluded from the test results that polypropylene-asphalt membrane will furnish a waterproof, dustproof wearing surface to any otherwise satisfactory subgrade for periods in excess of 2 years and will sustain many thousands of repetitions of pneumatic-tired convoy traffic without suffering significant damage, and MESL CONSTRUCTION IS EFFECTIVE IN PROVIDING A STABLE ROADWAY IN AREAS HAVING POOR DRAINAGE AND HIGH WATER TABLES.
