Geosynthetic Reinforced Soil - Integrated Bridge System (GRS-IBS)
The Montana Department of Transportation has released a report that identifies installation and construction techniques for a Geosynthetic Reinforced Soil – Integrated Bridge System (GRS/IBS) structure in Montana. GRS-IBS is a system that uses a series of alternating layers of granular fill material and fabric sheets of geotextile to create a composite reinforcement that provides support for the bridge slab. It has shown promise in other states.
