Roofing bitumen composition using rubber crumb
The results of the study of the process of obtaining a bitumen composition for cold-applied roofing materials are described. For this purpose, the modification of construction bitumen BNB 70/30 with rapeseed oil (RO) and rubber crumb (GK) from recycled tires was used. The effect of the concentration of RO and GK on the softening temperature, penetration, ductility, elasticity, flexibility at -25°C, and adhesion was studied.
