The Use of Deconstructed Tires as Elastic Elements in Railway Tracks
Elastic elements such as rail pads, under sleeper pads and under ballast mats are railway components that allow for a reduction in track deterioration and vibrations. And they are furthermore commonly used to obtain an optimal vertical stiffness of the infrastructure. However, the use of elastomeric materials can increase construction costs and the consumption of raw materials. Thus, the utiliz...
متن کاملRecycling of Scrap Tires
As Rachel Louise Carson (1907-1964) successfully noted in her phrase “The human race is challenged more than ever before to demonstrate our mastery not over nature but of ourselves”, we are challenged to find ways to produce more energy, reduce our waste production while minimizing use of limited natural resources. Although recycling of materials has a history going back to the times of Plato B...
متن کاملTires Back into Tires: Devulcanization of Tire Rubbers
The optimal process conditions for a high ratio of de-vulcanization to polymer degradation have been elaborated for tire rubbers: SBR, BR, NR and CIIR. These polymers all show their own particular breakdown characteristics, and the temperature dependence of the breakdown mechanism was investigated by measuring sol fractions and crosslink densities. For SBR and BR, the highest reduction in cross...
متن کاملWireless Monitoring of Automobile Tires for Intelligent Tires
This review discusses key technologies of intelligent tires focusing on sensors and wireless data transmission. Intelligent automobile tires, which monitor their pressure, deformation, wheel loading, friction, or tread wear, are expected to improve the reliability of tires and tire control systems. However, in installing sensors in a tire, many problems have to be considered, such as compatibil...
متن کاملGasification of Waste Tires
Gasification is a thermochemical pathways used to convert carbonaceous feedstock into syngas (CO and H2) in deprived oxygen environment. The process can accommodate conventional feedstock such as coal as well as discarded waste including plastics, rubber, and even MSW due to the high reactor temperature of 1000 to 1600oC. Pyrolysis is another conversion pathway yet it is more selective to the c...
