THE USE OF INFRA-RED SPECTRA IN THE ASSESSMENT OF BITUMEN DURABILITY

INFRA-RED ABSORPTION SPECTROSCOPY PROVIDES A VERY SIMPLE, RAPID, AND NONDESTRUCTIVE METHOD OF EXAMINING BITUMENS. THIS PAPER DISCUSSES EXPERIMENTAL TECHNIQUES AND PRESENTS SPECTRA FOR BITUMENS PRODUCED IN AUSTRALIA, INCLUDING THE SAME TYPES AS USED IN ROAD CONSTRUCTION BUT SOMEWHAT HARDER. CHEMICAL FUNCTIONAL GROUPS ATTRIBUTED TO ABSORPTION BANDS ARE CONSIDERED, AND AN INVESTIGATION OF THE APPLICATION OF THE TECHNIQUE TO THE STUDY OF BOTH DARK AND PHOTO-OXIDATION OF BITUMENS IS REPORTED. COMPARISONS BETWEEN SPECTROPHOTOMETER AND MICROVISCOMETER ASSESSMENTS OF OXIDATION RATES ARE ALSO INCLUDED. /RRL/A/
