ESTABLISHING LIMITS FOR ROAD ROUGHNESS BASED ON USER ASSESSMENTS OF SERVICEABILITY

Over recent years, there has been a growing tendency to systematise the engineering judgements surrounding road maintenance decisions. The schemes proposed have relied on combinations of subjective judgements and objective measures. While there is a lack of data concerning the reliability of subjective measures, the relationship between the objective measures and the quality of service provided by the road is not well substantiated. Objective measurements of road roughness have assumed particular importance. Although objective measures correlate well with subjective judgements of roughness, they correlate less well with judgements of tolerability. Evidence concerning the relationship between roughness, serviceability and tolerability is critically reviewed and some essential improvements to future attempts to assess tolerability limits are suggested.
