Fly Ash in Highway Construction
Coal fly ash is a coal combustion product that has numerous applications in highway construction. It has been used in roadways and interstate highways since the early 1950s. In 1974, the Federal Highway Administration urged states to allow partial substitution of fly ash for cement whenever feasible. Additionally, in 1983 the Environmental Protection Agency published federal comprehensive procurement guidelines for cement and concrete containing fly ash to encourage the utilization of fly ash and establish compliance deadlines.
This course provides basic technical information about the various uses of fly ash in highway construction. It presents the properties of fly ash that affect its use in roadway materials and reviews all of the major construction applications and methods currently in use.
Once you complete your course review, you need to take a multiple-choice quiz consisting of thirty (30) questions to earn 6 PDH credits.
