Considerations of energy, ecology and economics have prompted an examination of available technology for the use of flyash as a paving component. The economics of useage, however, varies and flyash use must be custom-engineered. Two example projects are described: the airport project at Newark, New Jersey, and the Port of Portland project. At Newark flyash was used as both aggregate and cementitions components. Costs for the flyash and lime were about half that of cement. Only half the manpower required with conventional methods was needed on this project. At the Port of Portland, flyash was not cheap and pozzolan (volcanic ash) was used. A brochure on the state-of-the- art and a user manual on the use of flyash is being prepared by the Federal Highway Administration. It is emphasized that the properties of flyash must be clearly understood in order that cost savings may be effected.
