Abstract: A method of determining moisture content in an emulsified asphalt-aggregate system is disclosed. The method includes: placing a first electrode in an emulsified asphalt-aggregate system (Mixture) at a first depth, placing a second electrode in the Mixture at a second depth, applying an alternating current (AC) signal between the first electrode and the second electrode, measuring impedance, determining the frequency which yields the minimum measured impedance, recording the minimum measured impedance, repeating the above steps at a predetermined time interval until the recorded minimum impedance is about 10 times of the first recorded minimum impedance, and alerting a user that the Mixture has sufficiently cured.
