Abstract: This report de scribes field experiments conducted using a combination of crushed lime stone, wood chips, sand, geosynthetics, fiber glass mats, plastic mats, and wood mats for expedient road construction over soft soils. Field sections were constructed and trafficked over two soft subgrades: a CBR less than 0.5 percent, and a CBR be tween 0.5 and 1.0 per cent. Experiment items were trafficked with 2,000 passes of a 41,600-lb, 5-ton military truck. Field experiment results indicated that plastic and wood mats, wood chips, and crushed lime stone are capable of providing structural support to military traffic over the two subgrade conditions. The fiber glass mats, geofoam, and ECM geosynthetic were not capable of with standing the applied traffic and are unsuitable for supporting substantial amounds of military traffic over the very soft subgrade conditions used in this experiment.
