Status:	Completed
Contact:	Last Name: Munley First Name: Eric P Telephone: 202-493-3046 E-mail: eric.munley@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
Office:	Office of Infrastructure Research and Development
Team:	Hazard Mitigation Team
Roadmap/Focus area(s):	Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:	Phase 1: Feasibility tests of the carbon nanotube (CNT) enhanced concrete for stress sensing in pavement. Fabricate self-sensing CNT enhanced concrete and use indoor and outdoor lab tests to evaluate their feasibility for detecting stress levels in pavement.Phase 2: Road test of the self-sensing CNT concrete for pavement health monitoring in a Minnesota Road Research Project (MnROAD) controlled road facility. Explore weigh-in-motion (WIM) detection feasibility. Perform road tests to evaluate the CNT enhanced concrete pavement for stress sensing in controlled road environments. The self-sensing concrete will also be explored for WIM detection.
Laboratories:	Not Applicable
Start Date:	March 9, 2010
End Date:	March 9, 2012
Funding Amount:	$284,979.00
FHWA Program Name:	Exploratory Advanced Research
Goals:	The key project objective is to develop a new intelligent self-sensing concrete pavement that can monitor its own structural health by continuously detecting internal stress level changes of the pavement.
Project Type:	Offsite
Background Information:	Data not yet available
Test Methodology:	Phase 1: (a) Indoor lab tests of the smart concrete for stress sensing (static, dynamic, impulsive) and influence of temperature and moisture; (b) Outdoor lab tests for stress sensing (including sensor design). Phase 2: (a) Methods for fabricating carbon nanotube on a large scale; (b) Road tests for carbon nanotube; (c) Feasibility study for weigh-in-motion data from nanosensors.
