PROPERTIES OF CEMENT AND LIME-FLY ASH STABILIZED AGGREGATE

Potential application of cement-fly ashaggregate, lime-fly ash-aggregate and limecement-fly ash-aggregate mixtures in pavement construction is reviewed in this paper. Engineering properties such as moisturedensity relationship, compressive strength, flexural strength, dry shrinkage, and freeze-thaw durability are summarized on the basis of past studies. Dry shrinkage and freeze-thaw characteristics of cement and lime-fly ash-aggregate mixtures containing sub-bituminous, self-cementitious Alberta fly ashes were evaluated in the laboratory. The stabilized aggregates are attractive for use in pavement structures because of their high strength and low drying shrinkage characteristics. Lime-fly ash stabilized aggregates are observed to shrink more than cement-fly ash stabilized aggregate. It is also concluded that the materials investigated may perform reasonably well under moderate freeze-thaw conditions in the base courses of pavements. Further research should be conducted to evaluate durability of such materials under appropriate freezethaw conditions.
