A DESCRIPTION IS GIVEN OF THE METHODS USED AND RESULTS OBTAINED IN EVALUATING A SPECIFIC NATURAL MINERAL DEPOSIT AS A POSSIBLE MINERAL FILLER FOR BITUMINOUS PAVEMENT MIXTURES. BY RESORTING TO A COMBINATION OF INSTRUMENTAL METHODS, PHYSICAL TESTS, AND CHEMICAL ANALYSIS, THE CLAY MINERAL NATURE OF THE MATERIAL AND ITS POTENTIAL BEHAVIOR AS A MINERAL FILLER WERE DETERMINED. THE METHODS USED INCLUDED INFRARED SPECTROSCOPY, X-RAY DIFFRACTION, DIFFERENTIAL THERMAL ANALYSIS, FINENESS, SURFACE AREA, AND PLASTICITY TESTS, CHEMICAL ANALYSIS, IMMERSION-COMPRESSION TESTS OF BITUMINOUS CONCRETE MIXTURES, AND SOFTENING POINT TESTS OF ASPHALT-FILLER MORTARS. THE REPORT EMPHASIZES THE MERITS OF COMBINING AVAILABLE TOOLS IN SUCH AN EVALUATION AND PARTICULARLY DESCRIBES THE USE OF INFRARED SPECTROSCOPY IN THIS CONNECTION. /AUTHOR/
