Composite Bitumen Binders Based on an Active Powder of Discretely Devulcanized Tire Rubber

Abstract:

Composite binders (CB) for road construction, based on bitumen and active powder of discretely devulcanized rubber (APDDR), obtained by the method of high-temperature shear grinding (HTSG), are considered. The formation of CB occurs with the introduction of APDDR in bitumen during the preparation of the asphalt mixture. The advantages of CB compared with bitumen in a wide temperature range are shown: a decrease in plastic deformations at high temperatures, an increase in fatigue life and resistance to the formation of low-temperature cracks.
