Manufacturing Technique Of Bitumen-Rubber Binder From The Recycled Tyres

Advantages use BRB in comparison with bitumen

Some comparative characteristics of binder materials BRB, polymer-bitumen blend, BITREK and initial oil bitumen

Sample Temperature ring & ball, °C Brittleness temperature, °C Elasticity at 0 °C, % Adhesion with stone materials
BRB 72 -31 35 Meets on control sample No 1 GOST 11508
BITREK 54 -20 30 Not data
Polymer-bitumen blend 65 -39 Not data Meets on control sample No 1 GOST 11508
Oil bitumen 90/130 47 -17 It is not normalized Does not maintain
