Project Details

Project Description: 

Geosynthetic Reinforced Soil (GRS) can be used for abutments and/or the integrated bridge system; however, adequate design and construction guidance have not yet been established for closely spaced systems (reinforcement spacing less than or equal to 12 inches). This project will pull together 40 years of research and inservice structures to develop a synthesis report compiling all the data available that can be used for deployment in the Federal Highway Administration's (FHWA's) Every Day Counts (EDC) initiative.


The key project objective is to compile the background and research necessary to support the design and construction guidelines. 


Deliverable Name: 
Geosynthetic Reinforced Soil Integrate Bridge System Synthesis Report
Deliverable Type: 
Research report or guidelines
Deliverable Description: 
This report is the second in a two-part series to provide engineers with the necessary background knowledge of Geosynthetic Reinforced Soil (GRS) technology and its fundamental characteristics as an alternative to other construction methods.
