National Concrete Pavement Technology Center

Project description

The overall objective of this study is to determine if these new sensors actually measure in-place compressive strength of concrete as stated. Additionally other advanced sensors will also be investigated. The specific objectives of this research are as follows: (1) review the state-of-the practice for piezoelectric and other NDT compressive strength sensors; (2) review the state-of-the practice for in-situ surface and bulk resistivity sensors; (3) laboratory testing of sensors; (4) field testing of sensors; and (5) cost-benefit analysis of adopting new technology providing it is feasible.
