In 1970 an FHWA Workshop defined major problems relating to improved pavements. The number one problem cited was the problem of relating pavement distress to pavement performance in an understandable predictable way. This report examines available data on all types of pavement distress and on several forms of pavement performance to define meaningful relationships. Regression analyses, Markov Processes, Bayesian Analysis, and Utility theory are examined as analytical tools useful in relating distress to performance. Several specific performance models of limited applicability are reported, along with some generally applicable techniques and recommended methods. This study shows that useful relationships can be obtained from existing data and are, in fact, being used in several states and other highway agencies. In each case, however, it is shown that significant improvements in the distress-performance relationships are needed which can only be obtained through the conscientious observation of distress and performance of pavements under a variety of environmental and load conditions for a reasonable period of time. e.g. (approximately ten years) Several suggestions and recommendations for improvement are included in the study.
