Abstract:

A round-robin experiment involving 10 laboratories, 5 mixtures, and 3 replicates for each mix was conducted to obtain data to serve as the basis for determining precision of the ignition method for measurement of asphalt content and gradation. Asphalt contents were also determined using reflux and centrifuge extractions as well as nuclear asphalt gage measurements. An ignition test procedure was developed for use with ovens not having an internal balance, which requires measurements of all weights as specific temperatures and a determination of appropriate burn times for specific materials. Test results indicated the precision is equal to that reported for reflux extractions and nuclear asphalt gages. Aggregate gradations were not changed by the ignition method to be implemented for determination of asphalt cement content of bituminous mixtures. 7 Firgures, 13 tables, 2 appendices, references. 105k, 31p.
