Pavement design requires the specification of design criteria, the generation of feasible
alternatives, the consideration of trade-offs, and the selection of the best overall choice.
Pavement design alternatives typically present the engineer with unavoidable trade-offs
between initial cost, maintenance cost, and design life. These trade-off decisions entail a
great deal of complexity and controversy, making it difficult to select the alternative that might

Pavement design requires the specification of design criteria, the generation of feasible alternatives, the consideration of trade-offs, and the selection of the best overall choice. Pavement design alternatives typically present the engineer with unavoidable trade-offs between initial cost, maintenance cost, and design life. These trade-off decisions entail a great deal of complexity and controversy, making it difficult to select the alternative that might be the best. A rigorous decision-analytic method that can be used to compare alternatives, multiattribute utility analysis (MAUA), is described, and its advantages over two traditional approaches, life-cycle costing and weighting methods, are described. An example that illustrates a pavement design selection problem in which alternatives present the designer with trade-offs between initial cost, maintenance cost, construction flexibility, and pavement life is presented, thus demonstrating the applicability of the MAUA approach.
