The Red Hills Plant near Ackerman, Mississippi produces a fly ash that does not meet the ASTM specification for either Class C or F fly ash; however, this material has been successfully used by a local consultant to stabilize embankment material. The purpose of this study is to evaluate this fly ash in a lime-fly ash (LFA) stabilized subgrade application for MDOT road construction. the MDOT Central Laboratory will evaluate a LFA mix design using the Red Hills fly ash for application in a field test section. Based on the results of this study, it is recommended that Red Hills fly ash be approved for use on MDOT projects.
