Design and Construction Guidelines for Geosynthetic Reinforced Soil Abutments and Integrated Bridge Systems
This online engineering PDH interactive presentation provides a brief overview of the design and construction of Geosynthetic Reinforced Soil (GRS) abutments and the Geosynthetic Reinforced Soil-Integrated Bridge System (GRS-IBS).
Geosynthetic reinforced soil (GRS) consists of alternating layers of compacted fill and closely spaced geosynthetic reinforcement. The technology has many applications, with bridge support being the focus of this design and construction presentation. This presentation also 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.
This 4 PDH online interactive presentation is applicable to benefit owners, designers, and construction personnel interested in implementing this technology while realizing how to design and construct a GRS-IBS that will have an estimated service life of at least 100 years.
This continuing education interactive presentation is intended to provide you with the following specific knowledge and skills:
Familiarizing with the technology of Geosynthetic Reinforced Soil (GRS)
Understanding the terminology associated with the technology
Learning about the methodology and steps required for GRS-IBS design and construction
Familiarizing with the design considerations for extreme events
Learning about the factors of in-service performance monitoring
Understanding the details associated with quality assurance, in-service inspection, maintenance, and repair
