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.
