This paper describes the procedures used by the New York State Department of Transportation to develop visual scales for assessing the condition of pavements in New York State. The paper describes the use of a psychometric scaling method known as Q-Sort to develop visual scales of pavement surface condition and the condition of base material that underlies the pavement. A panel of eight experts from the department's operating units reviewed more than 50 photographs of pavements and rated them on a scale of 1-10 for surface and base condition. Subsequent analysis produced a set of photographs representative of each position on the scales. Test-retest reliability was conducted by using the same eight judges two months later to demonstrate the replicative nature of the scales and their stability over time. These scales were then used to train scorers from the department's 11 regional offices, and scoring of the entire state highway system was conducted. Results were available within several weeks and summaries were made of the condition of the highway system in 1981. The paper concludes that the use of visual scales in highway scoring is a practical and accurate method of assessing pavement condition. It also concludes that, although the use of such scaling procedures has lagged in pavement analysis, their use should be expanded in the future as continuing assessments of highway condition are needed.
