MAGNETIC RESONANCE FOR IN-SITU DETERMINATION OF ASPHALT AGING AND MOISTURE CONTENT

This Innovations Deserving Exploratory Analysis (IDEA) project investigated the feasibility of using nuclear magnetic resonance (NMR) technology for in-situ determination of aging and moisture content of asphalt in pavements. The combination of NMR and electron paramagnetic resonance (EPR) techniques was shown to be an effective tool for assessing asphalt condition in pavements. Field verification of the system will be required for the IDEA product transfer. The recommended system design configuration and specifications, as presented in Appendix A, incorporates both NMR and EPR in an integrated, trailer mounted configuration using a common magnet.
