DETERMINING THE ASPHALT CEMENT CONTENT OF BITUMINOUS MIXTURES USING THE NCAT ASPHALT CONTENT OVEN

The purpose of this study was to develop a procedure for accurately and efficiently measuring the asphalt cement (AC) content of bituminous mixtures using the National Center for Asphalt Technology (NCAT) Asphalt Content Oven. The results were documented and a test procedure was written which incorporated the study findings. The results of this study demonstrate that the NCAT Asphalt Content Oven can be used to measure AC contents accurately. In addition to evaluating the NCAT asphalt content measurement method, an external scale method using the NCAT Asphalt Content Oven was developed. Using the external scale method the standard deviation for the differences between the actual and measured AC contents was 0.073 when applying a two-specimen mixture correction factor. The study set included 41 bituminous specimens. A mixture correction factor is required when measuring the AC contents of field produced samples.
