The research was funded by the Toll Road Division of INDOT. This report includes results from both laboratory and field experiments into the possible use of a rapid test for asphalt content of mixes containing slag aggregate. The report is forwarded for acceptance by INDOT. Respectfully submitted, D Douglas Winslow cc: A. Altschaeffl G. Henneke P. Owens Chameau K. Hoover B. Partridge J. W. Chen C. Letts C. Scholer W.

Abstroct The "nuclear" asphalt content gage was used with bituminous mixes containing slag aggregates to assess its applicability as a rapid analysis tool for these types of mixes. It was found to work as well, or better, than the standard extraction technique. It was also found to have additional advantages over the extraction technique since it is about an order to magnitude faster, requires no solvent and involves no decisions on the part of the user. 17.
