A 244-m (800-ft) long sand embankment test section was successfully constructed on a very soft foundation at mobile, Alabama, to verify the concept that a geotechnical fabric can be used as tensile rinforcement and to gain the experience needed to construct an additional 1280 m (4200 ft) of embankment. Based on expected behavior, criteria for fabric selection and special construction sequences were developed. Instrumentation was installed in the test section to evaluate embankment, fabric, and foundation behavior. Construction was accomplished by low-ground- pressure dozers. Conventional dump trucks were used to haul the embankment fill. Several different-fabric-placement schemes were evaluated. The embankment was constructed to design elevation without failure and, despite foundation pore-pressure levels that exceeded the height of the embankment, the bearing displacements and consolidation settlements were relatively small. The concept was found to be a technically feasible, operationally practical, and cost-effective method for rapid construction of embankments at locations where an unreinforced embankment would fail.
