INFLUENCE OF HIGHWAY PROFILES UPON TIRE DYNAMICS

THE DEVELOPMENT OF EQUIPMENT TO MEASURE THE POWER SPECTRA OF PAVEMENT SURFACE PROFILES AND THE DEVELOPMENT OF TECHNIQUES FOR USING POWER SPECTRA DATA TO PREDICT THE DYNAMIC RESPONSE OF VEHICLES IS SUMMARIZED. SPECIFIC OBJECTIVES INCLUDE: (1) RE-EXAMINE POWER SPECTRAL TECHNIQUES FOR PREDICTING VEHICLE RESPONSE TO PAVEMENT SURFACE PROFILES; (2) DEVELOP THE EQUIPMENT TO MODIFY A BPR TYPE ROUGHOMETER TO MEASURE POWER SPECTRA; (3) TEST THE EQUIPMENT AND DEVELOP OPERATING INSTRUCTIONS; AND (4) DETERMINE THE CORRELATION BETWEEN DATA OBTAINED WITH THE MODIFIED BPR TYPE ROUGHOMETER AND THE DATA OBTAINED BY A STANDARD UNIT FOR SEVERAL PAVEMENTS HAVING DIFFERENT CONDITION RATINGS. /FHWA/
