Military roads require high-strength foundation layers to support ground vehicles in the theater of operations TO. In many instances, sizable construction effort and costs are required in obtaining material and producing suitable roads. New road building techniques are needed to reduce the construction time and costs of these roads. The objective of this investigation was to develop construction techniques and procedures for employing a membrane- enveloped soil layer MESL as a base course to allow rapid road construction in the TO. Construction techniques for encapsulating in situ or locally available fine-grained soils in waterproof membranes were developed. A test road was built containing both MESL and conventional-type base courses. Traffic tests were conducted, and construction requirements for MESL base courses were determined.
