Behavior of FLY ASH in CementConcrete Pavement

Behavior of FLY ASH in Cement-Concrete Pavement

2016-4-23  Fly ash is a fine powder resulting from the combustion of powdered coal - transported by the flue gases of the boiler and collected in the Electrostatic Precipitators (ESP). Fly ash is defined in Cement and Concrete Terminology (ACI Committee 116) as the ‘finely divided residue resulting from the combustion of ground or powdered coal, which is transported from the fire box through the boiler by flue gases.

1996-2-1  Results from this study indicated that fly ash can be used as a mineral filler to improve resilient modulus characteristics and stripping resistance. The addition of fly ash did not significantly reduce field performance of asphalt concrete mix in terms of rut depth and present serviceability index but increase the amount of surface cracking in the pavement.

2010-9-7  The Class F fly ash provides the silica and alumina needed for cementitious reaction with lime to increase the strength, stiffness, and durability of the stabilized base layer. In addition fly ash acts as a mineral filler to fill the voids in the granular pulverized pavement mix, reducing the permeability of the FDR stabilized base layer.
