The Minnesota Department of Transportation (Mn/DOT) has been performing asphalt extraction testing on bituminous road materials for more than 50 years. Currently, Mn/DOT annually performs about 3,500 extractions. Extraction testing requires the use of chlorinated solvents, which generates a considerable amount of hazardous liquid waste that must be disposed of by strictly following increasingly complex and stringent federal regulations. The objective of this research project was to replace or supplement the current chemical extraction method for testing the asphalt content of road construction bituminous mixtures with nuclear asphalt gauge testing. This research led to the following conclusions: Nuclear asphalt gauge testing gives asphalt cement content results that are at least as accurate as solvent extraction testing; Gradation testing cannot be done using nuclear asphalt gauge testing procedures; Nuclear asphalt gauge testing works well for bituminous materials containing up to about 20 percent recycled asphalt pavement (RAP).
