DETERMINING AC CONTENT: INDUSTRY-AGENCY COOPERATION ADDRESSES ENVIRONMENTAL CONCERNS

This is a report of a meeting convened to address concerns of using chlorinated solvents for quality control and acceptance testinng at a meeting held in Portland, Oregon. A Federal Highway Admdinistration presentation highlighted the challenge in the quality control and acceptance testing of hot mix asphaltic materials. Alternative methods for measuring the asphalt cement content, namely, nuclear AC content gauges, biodegradable solvent usage, automatic plant recordation, and the monitoring of mix void properties and cold feed gradations are described. Quality assurance/quality control programs in various states are also discussed. Research and future research needs in this area are reviewed. This includes the asphalt-aggregate mixture analysis system being developed under the National Cooperative Highway Research Program (NCHRP Project 9-6(1).
