Method of and composition for producing a stabilized fill material

A method of producing and placing a stabilized fill material to construct a causeway across water or the like comprising mixture cement, fly ash, water and lime in the approximate proportions by weight 45-80% fly ash, 1-6% Portland cement, 20-50% water and 2% lime at a site remote from the site where it is to be utilized, trucking the fill material in a flowable state to the site where it is to be utilized, dumping the fill material while still in a flowable state at the edge of the water in which the fill material is to be placed and subsequently substantially immediately shoving the fill material still in a flowable state directly into the water by means positioned on previous fill material.

A method of producing and placing a stabilized fill material to construct a causeway across water or the like comprising mixing cement, fly ash, water and lime in the approximate proportions by weight 45-80% fly ash, 1-6% Portland cement, 20-50% water and 2% lime with the fly ash, cement and lime being first mixed by metering onto a traveling conveyor, conveying the mixed fly ash, cement and lime to mixing structure where moisture is added to the mixed fly ash, cement and lime, removing the mixed fill material in a flowable state from the mixing structure by dumping the fill material on one end of a conveyor and delivering the fill material to the utilizing site by means of the conveyor on which the fill material is dumped pivoted about the one end thereof to provide an arc at the other end of the conveyor on which the flowable fill material is dumped having the one end of the conveyor as its center and the conveyor as its radius which arc defines the periphery of the utilizing site, and moving the conveyors, mixing structure and storage hoppers for the cement, fly ash and lime toward the arcuate periphery of the dumping site as the causeway construction progresses.
