USE OF NUCLEAR METHODS TO MEASURE MINERAL FILLER CONTENT AND ASPHALTIC CONTENT OF BITUMINOUS CONCRETE
MINERAL FILLER CONTENT, FINENESS MODULUS OF AGGREGATE, AND STABILITY WERE USED TO INDICATE THE UNIFORMITY OF MIX BITUMINOUS CONCRETE PRODUCED AT VARIOUS MIXING TIMES. METHODS WERE STUDIED TO EVALUATE MINERAL FILLER CONTENT OF BITUMINOUS CONCRETE USING NEUTRON ACTIVATION AND THE ASPHALTIC CONTENT OF BITUMINOUS CONCRETE USING NEUTRON BACKSCATTER. THE BACKSCATTER TECHNIQUES DID NOT PROVE FEASIBLE FOR MEASUREMENT OF THE ASPHALTIC CONTENT OF IN-PLACE BITUMINOUS CONCRETE PAVEMENT, BECAUSE BACKSCATTER COUNT RATE IS INFLUENCED BY THE BASE ON WHICH THE RELATIVELY THIN BITUMINOUS CONCRETE LAYER RESTS. THIS STUDY INDICATES THAT NUCLEAR METHODS TO MEASURE CALCIUM MINERAL FILLER CONTENT AND ASPHALTIC CONTENT OF BITUMINOUS CONCRETE ARE FEASIBLE.
