Evaluation and Calibration of Road Meter Devices for Measuring Pavement Rideability

摘要

The report is divided into three parts. Part one covers the state of the art of Road Meter technology and describes some recent significant advances. The second part describes the evaluation of a velocity sensor for measuring axle movement to determine roughness rather than the normal method of mechanically determining the movement between axle and car body. Part three describes methods of Road Meter calibration, and limited testing of a dynamometer type calibration device constructed at the laboratory.
