IN CASE SHELLS BECOME SCARCE, STATE TESTS NEW SAND EMBANKMENTS

The construction of a relocated section of U.S. Route 90 through 13 miles of wetlands in Louisiana is described. In connection with this construction, the Louisiana Department of Transportation and Development is conducting tests on geotextile fabric techniques that could influence future embankment construction. Tests are being conducted because of the uncertainty of future supplies of the traditional embankment material, shells from a nearby lake. Shellls dont settle like sand but interlock and form a uniform mat foundation with a density of 70 to 100 pounds per cu ft. Bidders could choose shells on geotextile fabric without mucking out, or sand on fabric in mucked-out sections. Three types of geotextiles are being tested: polypropylene, polyester fabric and polyester geogrid. Different tensile strengths and arrangements of fabric are being tried.
