Evaluation of a Nuclear Asphalt Content Gage.

Abstract

The developments of nuclear asphalt content gages were reviewed and gage operation and use were studied in the laboratory to determine significant parameters that may affect nuclear gage results. Two Troxler Model 2226 Asphalt Content Gages, serial Nos. 307 and 308, were used in this study. Parameters investigated were (a) asphalt content; (b) moisture content; (c) aggregate gradation; (d) interactions of (a), (b), and (c); (e) sample size; and (f) sample temperature. Precision and accuracy experiments were conducted. These included (2 sup n) factorial experiments and stepwise multiple linear regression analyses of the results. Asphalt content determinations equaling or bettering those of the conventional extraction technique were obtained in considerably less time.
