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):	Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:	This projects aims to provide recommended specifications for the splicing of mild steel reinforcement in lightweight high-performance concrete members.
Laboratories:	Structures Laboratory Concrete Laboratory
Start Date:	October 1, 2006
End Date:	July 31, 2013
Funding Amount:	$100,000.00
FHWA Program Name:	Innovative Bridge Research and Deployment
Goals:	The key project objective is to develop recommended specifications for the splicing of mild steel reinforcement in lightweight high-performance concrete members.
Project Type:	Onsite
Background Information:	Data not yet available
Test Methodology:	The test approach was full-scale physical testing of structural members in combination with all necessary computational analysis.
Other Information:	Full-scale physical testing began in November 2008 and was complete in February 2009. Forty full-scale beam tests were completed in this project.
Partners:	Data not yet available
