Abstract

We suggest the method for the devulcanization and destruction of the rubber with the usage of high-boiling hydrocarbon products: coil and oil products as softening agents. Material obtained is the slip of the dissolved rubber-like products in hydrocarbon medium coinciding well with the road asphalt. The source of heat energy is the super-high frequency (SHF) radiation as more effective and economical. SHF field provides fast volume heating of secondary rubber raw material that makes it possible to exclude the operation of the tyres granulating. Removal of the formed products of devulcanization and destruction from the surface improves the process of heat and mass exchange.
