There is much concern over chlorinated solvents currently used for asphalt content extraction testing. This research was undertaken to investigate alternative methods that do not use chlorinated solvents for asphalt cement (AC) content determination. Methods considered include nuclear asphalt content gauges, extraction with biodegradable solvents, ignition oven, and recordation. Information was gathered from the literature, from a survey of all state highway agencies, and from interviews with selected agencies. The advantages and disadvantages of each of the alternative methods were identified and are presented in the report.
