Research de-vulcanization of tyres rubber in an ultrasonic field

In this work influence of weak ultrasound on process de-vulcanization a rubber crumbs of tyres waste has been investigated. Experiments were spent in stationary conditions in system bitumen - a rubber crumb of tyres waste. The process estimation de-vulcanization was carried out on changes of the temperature characteristics received as a result of ultrasonic processing, rubber-bitumen compositions. It is established that ultrasonic influence gives the chance fuller use of potential of a tyres waste, as source of caoutchouc. Researchers have shown efficiency of application of ultrasound for considerable improvement of physical-mechanical characteristics rubber-bitumen binding for the building materials maintained in the conditions of “a severe” climate.
