TRIAXIAL ACCELERATION ANALYSIS APPLIED TO EVALUATION OF PAVEMENT RIDING QUALITIES
TRADITIONALLY, THE RIDING QUALITIES OF A PAVEMENT ARE EXPRESSED AS SOME FUNCTION OF LOCALIZED IRREGULARITIES IN THE CONTOUR OF THE PAVEMENT SURFACE. MEASUREMENTS OF RIDING QUALITIES HAVE DEALT ALMOST EXCLUSIVELY WITH VEHICLE DISPLACEMENTS IN THE VERTICAL DIRECTION ONLY. DURING THE PAST FEW YEARS CERTAIN FEATURES OF HIGHWAY CONSTRUCTION AND USE HAVE EMPHASIZED SURFACE IRREGULARITIES THAT CAUSE SIGNIFICANT AMOUNTS OF COMBINED TRANSVERSE AND LONGITUDINAL MOTION. IN RESPONSE TO THIS NEED FOR DETERMINATION OF RIDING QUALITIES ON THE BASIS OF COMPONENT MOTIONS, AN INSTRUMENT FOR MEASURING AND RECORDING INDUCED ACCELERATIONS IN THE THREE PRINCIPAL DIRECTIONS WAS DEVELOPED AND ADAPTED TO A PASSENGER VEHICLE. THIS PAPER DESCRIBES THE EQUIPMENT AND ITS USE IN EVALUATING RIDING QUALITIES OF VARIOUS PAVEMENTS IN KENTUCKY. /AUTHOR/
