RAPID DETERMINATION OF ASPHALT CONTENT USING PENNSYLVANIA PYCNOMETER

THIS PAPER DESCRIBES THE DEVELOPMENT AND TESTING OF THE PENNSYLVANIA PYCNOMETER PROPOSED FOR RAPID DETERMINATION OF ASPHALT CONTENT. THE METHOD IS BASED ON THE PROCEDURES OF ASTM D2041-67, WHICH HAVE BEEN MODIFIED TO ACHIEVE GREATER ACCURACY AND PRECISION ESSENTIAL FOR ASPHALT CONTENT DETERMINATIONS. THE PENNSYLVANIA PYCNOMETER HAS BEEN FOUND TO BE PRACTICAL IN USE AND FREE OF OPERATING INCONVENIENCES. ASPHALT CONTENT IS DETERMINED IN APPROXIMATELY 30 MIN BY WEIGHT-VOLUME RELATION AND BY THE AID OF NOMOGRAPHS. PAVING MIXTURES CONTAINING LIMESTONE, SAND, GRAVEL, AND SLAG AGGREGATES HAVE BEEN TESTED FOR ASPHALT CONTENT. RESULTS ARE COMPARED TO THOSE OBTAINED BY USE OF THE REFLUX EQUIPMENT. THE TEST DATA HAVE BEEN ANALYZED STATISTICALLY. GREATER ACCURACY IS INDICATED IN THE RESULTS OBTAINED BY THE PENNSYLVANIA PYCNOMETER. FOR HIGHLY ABSORPTIVE AGGREGATES, WHICH PRESENT PROBLEMS IN COMPLETE RETRIEVAL OF THE ASPHALT, THE PYCNOMETER METHOD HAS BETTER PROFICIENCY THAN THE REFLUX METHOD.
