CALIBRATION OF RESPONSE-TYPE ROAD ROUGHNESS MEASURING SYSTEMS

This report contains the results of an intensive study of response-type road roughness measuring systems (primarily Mays- and PCA-type road meters) for the purpose of developing calibration and correlation procedures. An artificial road bump approach is described as a simplified method for a calibration check of road meter systems. This method offers potential for calibrating systems over the moderate-to-rough range of the roughness scale. Currently available road meters are not generally suitable for assessing the roughness (smoothness) of newly constructed roads. The findings of this study will be of particular interest to highway and airport personnel responsible for collection and analysis of data on pavement surface characteristics, pavement rehabilitation and management programs, and testing and research activities.
