Geosynthetic Reinforced Soil - Integrated Bridge Systems (GRS-IBS) Showcase

(4 PDHs available)

GRS-IBS can help states and local public agencies meet the country's demand for small, single-span bridges by delivering low-cost, strong and durable structures in less construction time. The technology consists of three main components: the reinforced soil foundation, the abutment, and the integrated approach. Alternating layers of compacted granular fill and geosynthetic reinforcement provide support for the bridge. The closely spaced reinforcement and granular soil create an efficient composite material that is internally stable and capable of carrying significantly higher than design bridge loads with predictable and reliable performance. The designer places the bridge directly on the GRS- IBS substructure, creating a seamless and smooth transition between the bridge and approach roadway without using joints, deep foundations, approach slabs, or cast-in-place concrete.
