Project Details

Project Abstract: 

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.


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.
