Approximately 1.5 billion tyres are produced each year which will eventually enter the waste stream representing a major potential waste and environmental problem. However, there is growing interest in pyrolysis as a technology to treat tyres to produce valuable oil, char and gas products. The most common reactors used are fixed-bed (batch), screw kiln, rotary kiln, vacuum and fluidised-bed. Th...

Objectives: To determine the strength and swelling behavior of black cotton soil (expansive soil) using a shredded rubber tyre as an additive. Methods: Series unconfined compressive California Bearing Ratio (CBR) tests were carried out on mixed with 0%, 5%, 10%, 15% tyres, results compared untreated samples. The study also investigated influence characteristics by performing pressure test. Find...

The waste tyres represent a source of energy and valuable hydrocarbon products. Waste tyres were pyrolysed catalytically in a batch reactor under atmospheric pressure. The effects of basic catalysts (MgO and CaCO3) were studied on the pyrolysis products. The distribution ratio of gas, liquid and char with MgO and CaCO3 were 24.4:39.8:35.8 wt % and 32.5:32.2:35.2 wt % r...

Heavy aircraft main landing gear tyres skid immediately after touchdown as result of the high slip ratio between the tyres and runway, which lead to tyre wear and smoke. In this paper, the tyre wear is modelled on the Archard theory using ANSYS mechanical transient, to reveal the wheel’s dynamic and the tyre tread wear. The wheel’s dynamic and the amount of wear are calculated for initially sta...
