Geosynthetic Reinforced Soil (GRS) Timber Bridge: A Sustainable Bridge Construction for Low-Volume Roads

Project Information

Project ID:
FHWA-PROJ-11-0107
Project Abstract:

Demonstration of the feasibility of a single-span demonstration/test bridge combining the geosynthetic reinforced soil (GRS), Integrated Bridge System (IBS), and timber superstructure design. The project will showcase the use of renewable materials of engineered soils and woods in bridge construction. The team will collaborate with the Forest Products Laboratory (FPL) of the United States Department of Agriculture (USDA) to advance the construction of rapid and inexpensive single-span timber bridges.

Goals

The objectives of this project are to:

(1) Investigate the compatibility of geosynthetic reinforced soil (GRS) bridge design with a timber superstructure.

2) Field test, when possible, newer wood preservatives.

3) Monitor performance of the GRS-timber bridge system.
