Update on fly ash technology relating to highway construction : January 1983

TLDR: In the Proceedings of the Sixth International Ash Utilization Symposium held March 7-10, 1982, at Reno, Nevada as discussed by the authors, the authors reviewed the successful use of fly ash as filler in asphalt pavements, for soil stabilization, for base course construction, in hydraulic cement concrete, and as a grout for "mud-jacking" portland cement concrete pavements.

Abstract: This report abstracts the information concerning the use of fly ash in highway construction contained in the Proceedings of the Sixth International Ash Utilization Symposium held March 7-10, 1982, at Reno, Nevada. The Proceedings include 54 papers, only 25 of which are abstracted. Some of the information has been previously reported but new evaluations, particularly for fly ashes obtained from sub-bituminous coal, are presented. The papers reviewed show the successful use of fly ash as a filler in asphalt pavements, for soil stabilization, for base course construction, in hydraulic cement concrete, and as a grout for "mud-jacking" portland cement concrete pavements. These developments reflect the growing use and importance of fly ash in highway construction and the need for all highway engineers to become aware of its potential.
