This study focused on the development of practical recommendations that can be easily implemented by highway agencies to increase pavement life. This volume describes and provides information on design features and construction practices that improve pavement performance. A key focus was to develop canonical discriminant functions that can be used to discriminate between groups of pavements in the sense of being able to tell them apart. The pavements were grouped according to their performance classification, namely, above expectation, as expected, and below expectation. The canonical functions consist of linear combinations of the variables that describe and quantify the pavement design features, site conditions, and construction practices.
