Title:

EVALUATING HIGHWAY ELEVATION POWER SPECTRA FROM VEHICLE PERFORMANCE

Accession Number:

00206227

Record Type:

Component

Abstract:

A RELATIVELY NEW TECHNIQUE FOR DESCRIBING THE CONDITION OF A HIGHWAY HAS BEEN DEVELOPED WHICH CONSISTS OF MAKING A POWER SPECTRAL DENSITY ANALYSIS OF ELEVATION MEASUREMENTS OBTAINED FROM THE LONGITUDINAL PAVEMENT PROFILE. IN CALCULATING THE ELEVATION POWER SPECTRUM IT IS NECESSARY TO MAKE CERTAIN ASSUMPTIONS THAT INFLUENCE THE RESULTING SPECTRUM. THE QUESTION THUS ARISES AS TO THE VALIDITY OF THESE ASSUMPTIONS. A PROCEDURE IS DESCRIBED THAT WAS USED TO OBTAIN A PAVEMENT ELEVATION POWER SPECTRUM FROM DYNAMIC TIRE FORCE MEASUREMENTS. THIS INVOLVED THE EXPERIMENTAL DETERMINATION OF TIRE FORCES WHICH WERE USED AS A CRITERION OF VEHICLE PERFORMANCE. THE POWER SPECTRUM OBTAINED BY THIS PROCEDURE IS COMPARED WITH POWER SPECTRA CALCULATED FROM ELEVATION MEASUREMENTS /USING DIFFERENT ASSUMPTIONS/ TO CHECK THE VALIDITY OF THE ASSUMPTIONS. /AUTHOR/
