Abstract:This first volume report provides results of a detailed study to 1) identify distresses that cause significant loss of serviceability and/or maintenance in pavements; 2) identify material properties that significantly influence the occurrence of distress; 3) select the best theoretical or empirical models for predicting distress using material properties and other engineering parameters; and 4) develop a detailed research plan for utilizing the models selected to study the effects of the significant distresses and to optimize material properties for zero-maintenance pavements. The research resulting in the accomplishment of the goals described above also produced other separate and specific results that are reported and should prove useful in future research. These results include: 1) a set of definitions and examples for their use in describing pavement behavior and the occurrence of distress; 2) tabulations of distresses, material properties that affect specific distresses, and the material factors (e.g., asphalt content, type and gradation of aggregate, etc.) that affect specific material properties; 3) discussions of the various predictive models available; and 4) the results of a number of limited sensitivity analyses using various distress models.
