POLYMERIZATION PRODUCT AS AN ADDITIVE TO HIGHWAY BITUMENS

THE USE OF VAT RESIDUES FROM THE PRODUCTION OF SYNTHETIC FATTY ACIDS AS AN ADDITIVE TO BITUMENS INCREASED ADHESIVE PROPERTIES, BUT SIMULTANEOUSLY REDUCED THE STABILITY OF THE BITUMEN ON AGING, WHICH WAS ESTABLISHED BY THE CHANGE IN ITS PROPERTIES AFTER HEATING AT 160 DEGREES OR EXPOSURE TO ULTRAVIOLET LIGHT. BY TREATMENT OF THE VAT RESIDUES WITH LIME IN A REACTOR WITHOUT AIR, A POLYMER WAS OBTAINED CONTAINING CALCIUM SALTS OF HIGH-MOLECULAR-WEIGHT FATTY ACIDS 50-65%, HIGH-MOLECULAR-WEIGHT FATTY ACIDS 15-20%, UNSAPONIFIED MATERIAL OF A RESINOUS TYPE CONSISTING OF HIGH- MOLECULAR-WEIGHT ALCOHOLS AND KETONES 10-30%, AND SMALL AMOUNTS OF QUICKLIME GYPSUM, FATS, AND DICARBOXYLIC ACIDS. THIS POLYMER WAS A SATISFACTORY ADDITIVE (5-40%) FOR BITUMEN, INCREASING THE ADHESIVE AND COHESIVE PROPERTIES OF THE BITUMEN, WITH SIMULTANEOUS IMPROVEMENT OF ITS ELASTICITY, HEAT AND WATER RESISTANCE, AND STABILITY ON AGING. /AUTHOR/
