Abstract : This report records the construction of a 1/2-mile membrane-enveloped soil layer (MESL) road constructed at Fort Hood, Texas, in May 1972. The road was constructed to field test MESL construction techniques and to provide a MESL road for long-term evaluation. The soil was a gravelly sandy clay with some shell. It was encapsulated using 6-mil polyethylene as the lower membrane and polypropylene fabric and SS-lh emulsified asphalt as the upper membrane. Construction of the MESL required 48 working hours and was completed in a 6-day period. Eight-foot-wide shoulders were constructed, and an asphaltic single-surface treatment was applied. The MESL road was opened to traffic in June 1972. A traffic count in July 1972 indicated an average daily usage by 1793 vehicles, of which 24.5% was truck traffic and 75.5% was passenger car traffic.
