Project Description

Geosynthetic-reinforced soil-integrated bridge systems (GRS-IBSs) are an emerging technology with the potential to introduce significant time and cost savings to small bridge replacements by removing the need for driven piles. Unfamiliarity with the technical performance and construction operations has impeded implementation.

This project will advance the implementation of the technology by evaluating the construction and early service life performance of the Rustic Road GRS-IBS, which was constructed in early 2015, in Boone County, Missouri. This detailed case study will be coordinated with the results of a concurrent Midwest Transportation Center effort regarding implementation of GRS-IBSs.

Deficient small bridges are a significant concern for the nation’s transportation infrastructure, so advancing the implementation of time- and money-saving technology is essential to maintaining a “state of good repair.”
