Abstract

The International Road Roughness Experiment (IRRE) has had a double impact on the current practice of roughness evaluation. First it has upgraded the moving average statistics (CP) developed and used in Belgium for the assessment of evenness. The latter is based on a dynamic profilometer monitoring of the longitudinal profile of the road surface. Its scale of representation can be interpreted from different points of view (acceptability criteria associated with comfort and security, maintenance levels associated with structural integrity, and methods of assessment such as visual inspection). The link between CP scale and the roughness measures generated by response-type road roughness measurement systems (RTRRMS) adds a new dimension to the interpretation of the Belgian scale. It enables roughness to be predicted or estimated in terms of vehicle behavior because the RTRRMS results are expressed in scales simulating quarter-car response. The second impact is a consequence of the first. The IRRE demonstrates the need for further development of roughness evaluation and enhances the pavement management systems approach developed in Belgium in such a way that economic considerations can be assessed through relations between roughness and users' costs.
