Abstract: A thermal process co-recycles tires with oils to produce gases, liquids and solids. The latter consisting of glass and steel fibers and a carbonous residue which are separately segregated and collected. By using selected additives gas formation and hydrogen sulfide contents are reduced, light product oil yields and quality are maximized and the level of chlorinated substances in the oils are reduced to trace amounts. The carbonous residue makes an excellent modifier for improving performance properties of bituminous binders and bituminous mixtures and for providing added benefits to properties of Portland concrete.
