ROUGHNESS INDEX STANDARDS FOR SASKATCHEWAN PAVEMENTS

A BRITISH MULTI-WHEELED PROFILOMETER WAS USED TO ESTABLISH TENTATIVE ROUGHNESS INDEX STANDARDS FOR ASPHALT PAVEMENTS IN SASKATCHEWAN. INDICES WERE BASED ON PROFILOMETER INTEGRATOR PLOTS, PROFILES, AND CLASSIFIER READINGS FROM APPROXIMATELY 150 MILES OF SELECTED STANDARDS PAVEMENT EFFECTS AND COMPARED WITH SUBJECTIVE PERFORMANCE RATINGS BEFORE INDEX STANDARDS WERE SET. ANALYSIS OF DATA INDICATED THAT PAVEMENTS RATED GOOD BY SASKATCHEWAN MATERIALS PERSONNEL HAD CORRECTED ROUGHNESS INDICES OF 38 INCHES PER MILE OR LESS. THE STANDARDS ARE TENTATIVE, PENDING ANALYSIS OF 1966 DATA. /CGRA/
