Temperature Effect on the Process of Road Bitumen Modification with Carbonized Residue from the Waste Tires Pyrolysis
The possibility of utilizing solid carbonized residue (CR) obtained in the pyrolysis of waste automobile tires (WT) was analyzed. On average, as a result of WT pyrolysis, about 36 wt. % of carbonized residue is obtained, which can serve as an adhesion additive and/or aging inhibitor in modifying petroleum bitumen. The CR obtained at a small-tonnage industrial plant and bitumen of the BND 70/100 brand produced by PJSC "Ukrtatnafta" were analyzed.
