PMSS Project Details

Project ID:	FHWA-PROJ-11-0061
Project Name:	Performance Tests for Geosynthetic Reinforced Soil (GRS)
Status:	Active
Contact:	Last Name: Nicks First Name: Jennifer E Telephone: 202-493-3075 E-mail: jennifer.nicks@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
Office:	Office of Infrastructure Research and Development
Team:	Bridge and Foundation Engineering Team
Roadmap/Focus area(s):	Not Applicable
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.
Laboratories:	Structures Laboratory Geotechnical Laboratory
Start Date:	August 15, 2011
End Date:	May 31, 2013
Funding Amount:	$0.00
FHWA Program Name:	Innovative Bridge Research and Deployment
Goals:	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).
