This manual provides information on the design and construction of Geosynthetic Reinforced Soil (GRS) abutments and the Geosynthetic Reinforced Soil-Integrated Bridge System (GRS-IBS). It serves as a follow-up to the Geosynthetic Reinforced Soil Integrated Bridge System Interim Implementation Guide. As such, it includes several updates based on continued research conducted at the Federal Highway Administration’s Turner-Fairbank Highway Research Center, as well as user feedback resulting from the use of GRS in the construction of more than 300 bridges.
Revisions include additional details on the design, construction, quality assurance, in-service inspection, maintenance, and repair of the GRS-IBS, along with revised material specifications, site selection criteria, and hydraulic guidance. The manual will benefit owners, designers, and construction personnel interested in implementing this technology.

| 16. Abstract
This manual outlines the state of the art and recommended practice for designing and constructing geosynthetic reinforced soil (GRS) technology for the application of abutments and the Integrated Bridge System (IBS). It was developed to provide engineers with the necessary background knowledge of GRS technology and its fundamental characteristics as an alternative to other construction methods. This manual presents step-by-step guidance on the design of GRS-IBS using the Load and Resistance Factor Design methodology. Material specifications for standard GRS-IBS are also provided. Detailed construction guidance is presented along with methods for the inspection, performance monitoring, maintenance, and repair of GRS-IBS. Quality assurance and quality control procedures are also covered. The procedures presented are based on 40 years of State and Federal research and deployment efforts focused on GRS technology for bridge support. |
