Project ID:	FHWA-PROJ-12-0040
Project Name:	Small-Scale Viscoelastic Continuum Damage (VECD) Protocol
Status:	Active
Contact:	Last Name: Gibson First Name: Nelson H Telephone: 202-493-3073 E-mail: nelson.gibson@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
Office:	Office of Infrastructure Research and Development
Team:	Pavement Materials Team
Roadmap/Focus area(s):	Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:	This project seeks to deliver the ability to utilize the Asphalt Mixture Performance Tester (AMPT) to measure in-place, as-constructed dynamic modulus and fatigue characteristics of pavement layers when lift thickness does not allow the full-size geometry to be obtained from construction.
Laboratories:	Bituminous Mixtures Laboratory
Start Date:	June 4, 2012
End Date:	June 4, 2014
Funding Amount:	$0.00
FHWA Program Name:	Turner-Fairbank Highway Research Center
Goals:	(1) To determine the similarity of cyclic fatigue properties of 38 mm diameter specimens as compared to 100 mm diameter specimens in the Asphalt Mixture Performance Tester (AMPT). (2) To determine the suitability of rapid simplified monotonic test protocol to capture same or similar fatigue characterization as cyclic fatigue in the Asphalt Mixture Performance Tester (AMPT).
