ABSTRACT:
A composition and method for producing an improved lime-fly ash-aggregate is disclosed. The composition is prepared by mixing together lime, flyash, graded aggregate, adding water, and from 0.5 to 4 percent, based on total dry weight, of sludge from a water treatment plant. The mixture is placed on top of a prepared subgrade, spread uniformly, and compacted to a high degree of relative density to provide the main load-carrying component of a road, airport runway, parking lot or the like.
