• Abstract:
  A Self-Calibrating Road Roughness Device known as the Walker Roughness Device (WRD) or Siometer has been under study and evaluation by the Department for the last several years. This device looks promising as a tool to collect road roughness for the Pavement Evaluation System. There is a very definite need for an automated data collection system for road roughness to eliminate some of the cost for this operation. This project was initiated to upgrade the WRD and develop procedures so it can be used for collecting serviceability index roughness measurements for the state. This report describes the procedures for correlating the WRD with the SDP and using the WRD for roughness measurements.
