Measurement and use of road roughness

The NAASRA roughness meter is a vehicle mounted device which measures axle body displacements at highway speeds. The development and use of the meter over a ten year period, means of recording and storing results and areas requiring further resolution are discussed. In this ten year period, a large amount of data has been collected and this has assisted in definition of problem areas. The meter itself is robust, its output is sensitive to user opinion of ride, and a variety of readout and recording options have been developed to cater for current and projected use. Concomitant development of data processing and storage systems puts road authorities in a favourable position to maximise use of results. Use has ranged from specific pavement evaluation studies to broad scale planning studies, where roughness has been adopted as a key parameter. The areas where further work is required include calibration, and the use of roughness to predict pavement performance (a).
