EFFECT OF FILLERS ON ASPHALTIC CONCRETE MIXES

THIS STUDY, ATTEMPTS TO DETERMINE THE EFFECTS ON A FILLER ON THE PROPERTIES OF ASPHALTIC CONCRETE MIXES. THREE DIFFERENT TYPES OF AGGREGATES, CRUSHED GRAVEL, CRUSHED HARD LIMESTONE, AND CRUSHED SOFT LIMESTONE, WERE USED IN CONJUNCTION WITH TWO DIFFERENT TYPES OF FILLERS, CRUSHED LIMESTONE DUST AND PULVERIZED LOESS, IN THE PREPARATION OF A SERIES OF ASPHALTIC CONCRETE MIXES. THE MIXES CONTAINED 0, 2 1/2, 5, 7 AND 10 PERCENT MINUS 200-MESH FILLER AND ASPHALT CONTENTS FROM 4 TO 8 PERCENT OF AN 85 TO 100 PENETRATION ASPHALT CEMENT. THE MIXES WERE TESTED FOR MARSHALL, HVEEM AND IOWA STABILITIES, HVEEM COHESION, VOIDS IN COMPACTED SPECIMENS; AND TRAFFICABILITY UNDER A MOVING LOAD IN A TRAFFIC SIMULATOR. A SUPPLEMENTARY SERIES OF TESTS WAS ALSO MADE TO ASCERTAIN THE EFFECTS OF SMALL QUANTITIES OF ASBESTOS ADDED TO SOME OF THESE MIXES. THE RESULTS OF THE STUDY INDICATE /A/ THAT QUANTITY TYPE OF FILLER USED IN CONJUNCTION WITH FIXED QUANTITIES OF BINDER HAVE A MATERIAL EFFECT ON THE PROPERTIES OF MIXES, /B/ THAT THE TYPE OF AGGREGATE USED IN MIXES CONTAINING THE SAME QUANTITIES OF FILLER AND OF BINDER HAS ITS EFFECT ON MIX PROPERTIES, /C/ THAT SOME METHODS OF TEST FOR PROPERTIES OF MIXES ARE MORE SENSITIVE TO THE EFFECTS OF FILLERS THAN OTHERS, /D/ THAT STABILITY ALONE IS NOT ALWAYS A DEPENDABLE CRITERION IN DETERMINING MIX BEHAVIOR UNDER MOVING LOADS, AND /E/ THAT CERTAIN QUANTITIES OF ASBESTOS IN CERTAIN MIXES HAVE A BENEFICIAL EFFECT ON PROPERTIES OF MIXES TESTED UNDER MOVING LOADS. /AUTHOR/
