DEMONSTRATION PROJECT NO. 59: THE USE OF FLY ASH IN HIGHWAY CONSTRUCTION, FAYETTE COUNTY, KENTUCKY

This report summarizes preliminary site investigations, design criteria and procedures, construction criteria and procedures, and results of initial and final evaluations of an experimental road base utilizing lime kiln dust, fly ash and aggregate. Observed performance has been satisfactory. Compressive strength evaluations indicate exceptional early strength and continued strength gain of the pozzolanic base. Backcalculation of specific elastic layer moduli indicate that the modulus of the pozzolanic base material is most likely within a range of 500,000 to 1,000,000 psi. Based upon observations to date, treated bases enhance overall pavement performance and their use should be continued. It is quite probable that pavement life may be extended at reduced costs.
