YARDSTICK FOR GUIDANCE IN EVALUATING QUALITY OF ASPHALT CEMENT

SAMPLES OF PAVING MIXTURES PRODUCED AT VARIOUS PLANTS AND USING MANY DIFFERENT ASPHALT CEMENTS FROM DIFFERENT CRUDES AND REFINERIES WERE TESTED BY THE LABORATORY. LOW TEMPERATURE DUCTILITY PROVIDES A METHOD OF MEASURING THE FUTURE SERVICES BEHAVIOR OF ASPHALTS AND THE PAVEMENTS IN WHICH THEY ARE INCORPORATED. AN IMPROVED LABORATORY METHOD PROVIDES A TOOL WHEREBY THE SIMULATION OF THE HOT-MIX PUGMILL OPERATION ON A LABORATORY BASIS CAN BE DUPLICATED. THIS PROCEDURE WILL ALLOW AN EVALUATION OF THE ASPHALT BEFORE IT IS PLACED. IT WAS DETERMINED THAT ANY PAVING MIXTURE WHICH CONTAINS AN ASPHALT WHICH SHOWS A DUCTILITY EXCEEDING 8CM SHOULD BE FREE FROM CRACKING.
