UTILITY DECISION ANALYSIS TO SELECT AGGREGATES FOR ASPHALT PAVEMENTS.

A literature review and a survey of current state practices resulted in the identification of four alternative schemes that are used in the states for evaluating the quality and performance of aggregates. The schemes mainly differ in the relative emphasis put on the aggregate tests, asphalt mix tests, service experience, and the prequalification of aggregate sources based on certain aspects. The relative usefulness of the four schemes was evaluated by means of the utility decision analysis. It is also noted that there is a need to consider other factors such as aggregate reserves, production costs, haul distances, environmental factors, and energy use in addition to the evaluation of quality of an aggregate.
