A LABORATORY PROGRAM TO INVESTIGATE AND EVALUATE STABILIZED MIXES UTILIZING FLY ASH GENERATED IN NEW YORK STATE

This report is a presentation of mix design concepts and a mix design procedure developed by the New York State Department of Transportation, Soil Mechanics Bureau. Also included are summaries of classification, unconfined compressive strength andd durability test data. Preliminary specifications for cement-fly ash-aggregate and lime-fly ash-aggregate mixes to be used on a planned off-highway demonstration project are in the Appendix. Stabilized cement-fly ash-aggregate mixes demonstrate considerable potential use in the pavement section. Laboratory testing demonstrated stabilized lime-fly ash-aggregate mixes require longer cure periods than those required for cement stabilized sections, thereby precluding their use on some construction projects. Both mixes, when properly cured, have adequate compressive strength and durability to be used as base or subbase courses in the pavement section. Developing the use of fly ash in stabilized courses will require the electric generating companies to consistently provide and properly store fly ash of acceptable quality. (Author)
