Abstract：The geosynthetic reinforced soil-integrated bridge system (GRS-IBS) is a refined development of geosynthetic reinforced soil (GRS) abutment, for “Bridge of the Future Program”, to meet demands for the next generation of more than 500,000 small to medium single-span bridges in America. The advantages of this new technology include reduced construction time and cost, generally fewer construction difficulties, and easier maintenance over the lifecycle of the structure. These advantages have led to a significant increase of construction of GRS-IBS structures in almost every state of America in recent years. However, no engineering practice of GRS-IBS appears in China up to now. Authors of this article collect the case studies to analysis and summarizes the structural characteristics and work performance of GRS-IBS. The results show that the structure usually has a unified structural form and technical characteristics, such as the reinforcement spacing is generally 0.2m, the surface layer type is generally modular, etc.; the structure has the advantages of simple and rapid construction, cost saving, etc.; and good service performance such as small settlement is also worth to mention.
