Discrete Fiber Reinforcement of Sands for Expedient Road Construction

Abstract

This report describes laboratory and field experiments conducted using discrete synthetic fibers to stabilize sands for expedient road construction. Unconfined compression tests were conducted as an index of material performance to identify the effects of fiber type, length, content, denier, and sand type on load-bearing capacity. Field sections consisting of 8-in. fiber-stabilized layers over a sand subgrade (SP) were constructed and trafficked to validate the laboratory results under actual field conditions. Experiment items were trafficked with 10,000 passes of a 41,600-lb 5-ton military truck. Test results showed that fiber-reinforced sand materials are capable of providing structural support to military traffic over sand subgrades. The results revealed optimum stabilization parameters, practical construction technique, and effective maintenance procedures. Design, construction, and maintenance guidance are provided for using fiber-reinforced materials to support substantial amounts of military traffic.
