Roadmap/Focus area(s):	Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:	Recently, more emphasis has been placed on the use of lightweight or specified density concrete as a solution for several bridge applications. The properties of these materials result in applications that have lighter transportation loads, require smaller construction equipment, and result in extended span ranges and reduced inertia forces. The American Association of State Highway and Transportation Officials specifications for designing with these materials have not been significantly updated since the 1960s. This work, along with the work of National Cooperative Highway Research Program Project 18-15, intends to update the specifications appropriately for the modern version of these materials. This specific portion of the overall program focuses on prestressing strand bond to lightweight concrete.
Laboratories:	Structures Laboratory Concrete Laboratory
Start Date:	June 1, 2010
End Date:	September 30, 2013
Funding Amount:	$30,000.00
FHWA Program Name:	Innovative Bridge Research and Deployment
Goals:	This project aims to quantitatively assess the bond slip performance of the specific prestressing strand embedded within the full-scale test girders tested in the project titled "Transfer and Development Length Behavior of Lightweight High Performance Concrete Girders." The testing will be completed through the newly developed Standard Test for Strand Bond.
