In order for zero-maintenance pavements to be constructed, the materials from which they are built must withstand severe stresses without suffering extensive distress. In evaluating the conditions for which zero-maintenance pavements must be designed, it is necessary to clearly define and categorize these distresses, determine their causes, and rank the material properties that affect each distress in order of importance. The process used to prioritize these distresses and the material properties related to them is described, and a set of definitions on which this process is based is presented. The result of this effort is a minimum set of distresses and material properties that affect those distresses that must be considered in designing zero-maintenance pavements. Categories of distress noted in field surveys were ranked based on these definitions and processes. Only distresses that occur in premium pavements were included in the analysis, and each was evalutated to determine its impact on meeting the requirements for zero-maintenance pavements. The evaluations presented are subjective but were developed by using the experience of the project staff and sensitivity analyses based on models that predict distress. A detailed set of distresses and major material properties that affect those distresses are given for rigid, flexible, and composite premium pavements. (Author)
