| 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. | |
| 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. | |
| Product Type: | Research report | |
| 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. | |
| Expected Benefits: | The expected benefit is the enhancement of continuous real-time monitoring of pavement health in a large area. Carbon nanotubes may also increase concrete strength and durability in a pavement environment. | |
| Deliverables: | Name: Initial research into use of carbon nanotube (CNT) in pavements. Product Type(s): Research report Description: Carbon nanotubes (CNTs) may enhance real-time monitoring of pavement health in a large area continuously. Carbon nanotubes may also increase concrete strength and durability in a pavement environment. | |
