ASPHALT CONTENT DETERMINATION USING NUCLEAR TECHNIQUES
AN EVALUATION WAS MADE OF THE APPLICATION OF THE TROXLER NUCLEAR ASPHALT CONTENT GAUGE, MODEL 2226, TO DETERMINE THE ASPHALT CONTENT OF HOT BITUMINOUS MIXES USING NEUTRON THERMALIZATION. PARALLEL DATA WERE ACQUIRED, WHERE CONVENIENT, BY THE USE OF A NUCLEAR-CHICAGO ASPHALT CONTENT GAUGE, MODEL 9999, PREVIOUSLY EVALUATED. DATA WERE FIRST ACQUIRED FOR VARIABLES OF MIX DESIGN (GRADATION), AGGREGATE TYPES, AND ASPHALT PROCEDURES FOR BITUMINOUS MIXES WITH VARIOUS REPRESENTATIVE ASPHALT CONTENTS. THESE INITIAL SAMPLES WERE MIXED UNDER CONTROLLED LABORATORY CONDITIONS. COMPARISONS WERE MADE OF DESIGN ASPHALT CONTENTS, IMMEREX EXTRACTION VALUES ON THE SAME SAMPLES, AND THE VALUES DETERMINED WITH THE TWO NUCLEAR UNITS. FIELD TESTS OF THE TROXLER GAUGE WERE ALSO CONDUCTED AT VARIOUS BATCH PLANTS WITH RESULTING VALUES COMPARED TO EXTRACTED ASPHALT CONTENT ON THE SAME SAMPLE.
