Description: | Technical Report Abstract: This report describes laboratory and field tests conducted using a new fiber stabilization technique for sands . Laboratory unconfined compression tests using 2-in.-long monofilament polypropylene fibers to stabilize a poorly graded (SP) sand showed an optimum fiber content of 1 percent (by weight). Field test sections were constructed and traffic tested using simulated C-130 aircraft traffic (30,000-lb tire load at 100-psi tire pressure) and military truck traffic (5-ton military cargo truck loaded to a gross weight of 41 ,600 lb). Test results showed that sand-fiber stabilization over a sand subgrade supported over 1,000 passes of a C-130 tire load with less than 2 in. of rutting. The top 4 in. of the sand-fiber layer was lightly stabilized with Road Oyl to provide a wearing surface. Based on limited truck traffic tests, an 8-in.-thick sand-fiber layer, surfaced with a spray application of Road Oyl, would support substantial amounts of military truck traffic. |
