• Description:
  This report is concerned with the evaluation of the Yale vacuum pycnometer to determine the feasibility of its use for the rapid determination of maximum specific gravity and asphalt content of bituminous paving mixtures. Asphalt contents of plant-mixed samples from four Louisiana mix types were calculated from the pycnometer determined maximum specific gravities. A comparison of these asphalt contents with both the known and the reflux extraction asphalt contents of these samples would indicate: (1) the accuracy and precision of the Yale pycnometer in determining asphalt content was equivalent to that of the reflux extraction for 3 of 4 mix types tested; and (2) the poor results obtained with the fourth mix type were caused by the inconsistent effective specific qravities associated with a highly absorptive expanded clay aggregate.
