Eight empirical studies of user rating of pavement serviceability are reviewed, and it is concluded that pavement roughness (or rideability) is the prime determinant of serviceability rating. For the studies considered, the proportion of variability in rating score attributable to a linear regression against roughness ranged from 66 to 93 per cent. Surface condition also rated highly in user surveys of factors which determine the quality-of-service provided by a road. The new profile-based methods of calibrating roughness meters and correlating roughness measured are reviewed. The International Roughness Index profile statistics is used to compare the results of earlier Australian serviceability rating studies with those obtained overseas. Methodological aspects of serviceability rating studies, including sample size requirements and the effects of different vehicle types and sample populations, are reviewed. Detailed recommendations are made for the conduct of an Australian serviceability rating study aimed at developing Pavement User Rating Indices.
