A simple test procedure has been developed that greatly speeds the determination of the asphalt content of hot-mix bituminous mixtures. It involves a brief but thorough mixing of standard quantities of a bituminous mixture and trichloroethylene. The transmittance of light by the asphalt-trichloroethylene solution is then measured and correlated with the asphalt content of the mixture. The method takes about 5 min and uses reasonably inexpensive equipment that is highly portable. Preliminary tests indicate that the new method is as accurate as existing methods.
