Abstract : The construction and maintenance of membrane-enveloped soil layers (MESL) asbase courses on roadways are described. The concept involves complete encasement of a compacted layer of fine-grained soil by a lower and upperwaterproof membrane. The upper membrane is capable of supporting limitedrubber-tired traffic operations. It is formed by applying emulsifiedasphalt to the surface of the soil layer, placing polypropylene material,applying a second coat of asphalt, and then placing a blotter layer of sand.An MESL road system is applicable for use on roadways where materials forconventional construction of foundation layers are not available withoutconsiderable expenditure of time, effort, or money. Use of the MESL conceptas permanent road construction practice has not been proved feasible.
