|Project Description:||A performance test is a load test on a geosynthetic reinforced soil column. A resulting stress-strain (or load-settlement) curve describes the stiffness and capacity of that composite. Different factors that affect performance (e.g. reinforcement material, reinforcement strength, reinforcement spacing, backfill type) will be investigated.|
|Start Date:||August 15, 2011|

|FHWA Program Name:||Innovative Bridge Research and Deployment|
The key project objectives are to:
(1) Investigate the relationship between reinforcement spacing and reinforcement strength.
(2) Conduct a small parametric study on factors affecting geosynthetic reinforced soil (GRS) performance.
(3) Provide a database for calibration in load and resistance factor design (LRFD).
