Course Introduction
Coal fly ash is a coal combustion product that has numerous applications in highway construction. Fly ash has been used in roadways and interstate highways since the early 1950s. In 1974, the Federal Highway Administration issued an official notice which urged states to allow partial substitution of fly ash for cement whenever feasible. In addition, to encourage the use of fly ash the Environmental Protection Agency published federal procurement guidelines for cement and concrete containing fly ash. The present course provides basic technical information for highway engineers who want to learn about the advantages of fly ash as originally envisioned by the FHWA and the EPA and as borne out by the subsequent experience of other engineers involved in highway construction.
