Techniques for Rapid Road Construction Using Membrance-Enveloped Soil Layers
The purpose of this instruction report is to provide information and guidance for the construction and maintenance of membrance-enveloped soil layers (MESL) as base courses on roadways in the theater of operations. The concept involves complete encasement of a compacted layer of fine-grained soil by a lower and upper waterproof membrane. The upper membrance is capable of supporting limited rubber-tired traffic operations. It is formed by applying emulsified asphalt 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 for conventional construction of foundation layers are not available without considerable expenditure of time, effort, or money. However, use of the MESL concept as permanent road construction practice has not been proved feasible. Construction techniques for roads with shoulders utilize the in-place roadbed soil in the MESL. The process involves removing the soil and stockpiling it on the shoulders, placing the lower membrance, replacing the soil on the lower membrance, compacting the soil layer, and then installing the upper wearing membrance.
