Discrete Fiber Reinforcement of Sands for Expedient Road Construction
This report describes laboratory and field experiments conducted using discrete synthetic fibers to stabilize sands for expedient road construction.MAny tests including compression tests were conducted as an index of material performance for studying the effects of fiber type, length, content, denier, and sand type on the load-bearing capacity of the soil. 8-in. fiber-stabilized layers field sections were kept over a sand subgrade. Such a road was constructed and vehicles were allowed pass over it to test the laboratory results in actual environmental conditions. 10,000 passes of a 41,600-lb 5-ton military truck included one of such tests. The tests revealed that in sand subgrades t fiber-reinforced sand materials are capable of providing structural support to millitary traffic. The stabilization parameters were optimum and the practical construction technique and effective maintenance procedures were used . Design, construction, and maintenance guidance were provided by the millitary for fiber-reinforced materials in order to support substantial amounts of military traffic.
