Investigation of Nuclear Asphalt Content Gauge
The introduction of new aggregate sources to Louisiana in the mid 1980s has presented problems in asphalt concrete mix design and construction. Current test procedures take several hours to determine asphalt content. In addition, the use of chlorinated solvents is being reduced nationally because of their hazardous storage, handling and disposal problems. This study evaluated the operation and performance of the nuclear asphalt content gauge as a replacement for existing methods to reduce test time and eliminate the use of hazardous solvents. The variation in test results between centrifuge, reflux and the nuclear asphalt content gauge was evaluated for one week's production at six asphalt plants. Three batch plants and three drum plants were examined.
