Design and Construction of a Geosynthetic Reinforced Soil Integrated Bridge System

An innovative alternative to conventional bridge support technology, the Federal Highway Administration's (FHWA) geosynthetic-reinforced soil-integrated bridge system (GRS-IBS) utilizes closely spaced layers of geosynthetic reinforcement and compacted granular fill material to provide direct bearing support for structural bridge members. This new technology has a number of unique advantages, including reduced construction time and cost, generally fewer construction difficulties, and easier maintenance over the life cycle of the structure. This technology can also perform well under a variety of static and dynamic loading conditions if designed and constructed properly. These advantages have led to a significant increase in the rate of construction of GRS-IBS structures in recent years. This paper provides details about the implementation of a GRS-IBS project in Delaware, the first project of this type in the state. An overview of the design and construction process for this project is provided, along with a brief description of a custom-designed instrumentation system for monitoring the long-term performance of the GRS-IBS.
