Project Name:	Development of Advanced Connection Systems for Adjacent Concrete Box Beams
Status:	Active

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:	Project includes the full-scale structural testing of four independent connection systems for adjacent box beams. Each system will be tested under millions of cycles fatigue loads in order to replicate decades of distress on the bridge system. Two of the connection systems will include conventional grout and transverse post-tensioning. Two of the connection systems will include field-cast UHPC and no transverse post-tensioning. Findings should include recommendations of anticipated behavior from good current practice systems as well as advanced systems that potentially offer simplified construction and better long-term performance.
Laboratories:	Structures Laboratory
Start Date:	October 1, 2012
End Date:	October 31, 2014
Funding Amount:	$350,000.00
FHWA Program Name:	IRT (Infrastructure Research and Technology)
Goals:	This objective of this project is to advance the state-of-the-practice for longitudinal connections between adjacent box beams, thus allowing broader use of this very cost effective bridge superstructure system.
