ROAD AGGREGATE CAN BE MADE FROM INCINERATOR ASH

INCINERATOR RESIDUE IS POTENTIALLY AN EXCELLENT MATERIAL TO USE AS ROAD AGGREGATE, ACCORDING TO P. E. D. MORGAN OF THE FRANKLIN INSTITUTE. HE HAS "SLAGGED" (PARTIALLY MELTED) RESIDUE IN A LABORATORY ARC FURNACE AND FOUND THE CRUSHED PRODUCT TO BE AN ACCEPTABLE AGGREGATE FOR HIGHWAY USE. PHILADELPHIA PRODUCES 165,000 TONS OF RESIDUE EACH YEAR AND PURCHASES 165,000 TONS OF AGGREGATE FROM CONVENTIONAL SOURCES. IT MAY BE AN ADVANTAGE TO SUPPLY MOST OF ITS AGGREGATE NEEDS FROM RESIDUE. ECONOMICS AT PRESENT ARE NOT COMPLETELY FAVORABLE - THE COST OF THE SLAGGING PROCESS IS ABOUT $4/TON WHICH, COMBINED WITH A $1/TON COST FOR DELIVERY, IS MORE THAN THE $4.05/TON PRICE FOR AGGREGATE. BUT THE INCREASED COST OF LANDFILLING THE RESIDUE, THE PRESENT DISPOSAL METHOD, MAKES THE SLAGGING PROCESS MUCH MORE ATTRACTIVE. /AUTHOR/
