REVIEW OF CURRENT STATE PRACTICES RELATING PAVEMENT DISTRESS AND PERFORMANCE

A small workshop was held to define the procedures for determining the relationship between pavement distress and performance. The objective was to relate predicted distress to measured performance. The data presented in this circular were collected using a questionnaire which was sent to all state highway departments-and other agencies. These questions were the first of their kind to be used in a study to relate distress to performance. Very few of the states responding to the questionnaire demonstrated a clear-understanding of the relationship of distress to performance. Off all the methods to determine this relationship, the methods employed by Florida, Ontario, Utah and Washington appeared to be the furthest along. Adopting a common precedure is now needed to ensure optimal results. The questionnaire points out that state agencies must adopt more uniform techniques of data collection if the distress-performance relationship is to become an integral part of pavement design.
