COURSE NO: T06-003
Fly Ash Facts for Highway Engineers
Course Highlights

This online engineering PDH course provides basic technical information for highway engineers who want to learn about the various uses and 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.


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.


This 6 PDH online course is intended primarily for a highway engineers seeking to learn the advantages of using fly ash in highway construction.
