A Guide to Fiber-Reinforced Polymer Trail Bridges
Introduction
native logs has left small clear cuts around the bridge site. Increasing recreational use and tightened budgets also contribute to the need for lightweight,
low-maintenance bridges that are easy to construct.
Fiber-reinforced polymer (FRP) bridges, commonly called fiberglass bridges, offer a potential solution. FRP trail bridge members are fabricated from reinforcing
resins (commonly referred to as polymers or plastics) and strands of materials (usually fiberglass) with tensile and bending strengths comparable to those of steel or concrete.
