Title: PROBLEMS ENCOUNTERED IN USING ELEVATION POWER SPECTRA AS CRITERIA OF PAVEMENT CONDITION
Accession Number: 00206675
Record Type: Component
Abstract: A POWER SPECTRUM, CALCULATED FROM HIGHWAY ELEVATION MEASUREMENTS, WAS USED AS A CRITERION FOR PAVEMENT CONDITION. THE CRITERION WAS INFLUENCED BY THE LOCATION, ACCURACY AND SPACING OF THE ELEVATION MEASUREMENTS, AND BY THE METHOD USED TO DETERMINE PAVEMENT ROUGHNESS FROM THE VARIATION IN MEASUREMENTS. THE INFLUENCE OF THESE FACTORS ON THE RESULTING POWER SPECTRUM WAS INVESTIGATED, AND THE PAVEMENT CONDITION CRITERION OBTAINED FROM SOME OF THESE SPECTRA WAS COMPARED WITH THE CORRESPONDING BPR ROUGHOMETER RATING FOR CERTAIN HIGHWAYS. THE NEED IS SHOWN FOR A STANDARDIZED PROCEDURE FOR OBTAINING ELEVATION MEASUREMENTS AND FOR MAKING POWER SPECTRUM CALCULATIONS, IF COMPARABLE CRITERIA OF PAVEMENT CONDITION ARE TO BE OBTAINED. /AUTHOR/
