Abstract: In this work, studies were carried out on the introduction of crumb rubber (RC) into road bitumen and bitumen-mineral mixtures and it was determined that for the modification of petroleum bitumen it is necessary to use only the tread part of a tire with a crumb size of 0.8-2 mm. The optimal amount of RC additive in bitumen is 4 -5%. In this case, the decrease in the penetration depth of the needle (penetration) at 25 ° C does not exceed 19% for BND bitumen 60/90, and 28% for Baki80 / 25 bitumen, while the extensibility decreases, respectively, from 98 to 17 0.1 mm and from 100 to 26 * 0.1 mm.
Key words: Bitumen, modification, penetration, rubber crumb, polymer, physical and mechanical parameters, softening temperature, swelling, frost resistance.
