Evaluation of nuclear asphalt-content gauges. Final report

Technical Report · Wed Mar 01 00:00:00 EST 1989

OSTI ID:7069668

The study evaluated the accuracy and precision of the Troxler, Model 3241-C, and CPN, Model AC-2, Nuclear Asphalt Content Gauges. To achieve precisions at plus or minus 0.15% 95% of the time, it was necessary to establish special procedures for making test samples, controlling environment, and calibration. Both gauges provided acceptable results utilizing a 3-point calibration. Their use in the field would be acceptable when the proper procedures are followed.
