one of the most important factors that affect tire friction is surface roughness, which determines the size of the real contact area, real pressure distribution on the contact interface, and scales of mechanical engagement between viscoelastic rubber and a rough substrate. the need to predict coefficient of friction (cof) for rubber on rough surfaces for applications such as traction of tires o...

with many years of construction and application of common concrete, researchers have always been searching for a better composition. one of the notable ideas for achieving such a composition is using recycled materials. one of the materials which is suitable for environment and constant development is damaged tires .for studying mechanical properties of concrete containing tire particles, a ser...

The natural frequencies and mode shapes of pneumatic tires are predicted using a geometrically accurate, three-dimensional finite element modeling. Tire rubber materials and cord layers are represented independently using “shell element” available in COSMOS. The effects of some physical parameters such as the inflation pressure tread pattern, thickness of belts and ply angles to the natural ...

Post-consumer glass represents a major component of solid waste. On the other hand, more than 100 million tons of coal combustion ash are generated in the U.S. annually, of which 60 million tons are fly ash. To deal with these problems, two new materials were developed: “glascrete” and “ashcrete.” They have the potential of being made almost entirely from recycled materials: crushed mix-color w...

An immense problem affecting environmental pollution is the increase of waste tyre vehicles. In an attempt to decrease the magnitude of this issue, crumb rubber modifier (CRM) obtained from waste tyre rubber has gained interest in asphalt reinforcement. The use of crumb rubber in the reinforcement of asphalt is considered as a smart solution for sustainable development by reusing waste material...

• Green tire with silica as the main reinforcing filler occupies a large slice of market and is difficult to recycle. An efficient controllable reclamation process silanized from waste green rubber by thermo-oxidative was proposed. The interfacial interaction between further interpreted. A stepwise separation reclaimed (r-SS) rubbers achieved using process, quantified. exfoliation residual boun...

Management of waste tires has become a leading environmental issue due to the global growth in number produced annually. This work is focused on exploring use Ground Tire Rubber (GTR) new class cost-effective, recycled composite materials. A Fused Filament Fabrication (FFF) desktop 3D printer used produce GTR-based material with up 50% wt. rubber filling. ABS as host matrix. Both microscopic an...

The aim of this study was to assess the impact natural rubber tire waste charcoal (NRTWC) amendment on carbon mineralization in tea cultivated soils low country wet zone Sri Lanka. NRTWC applied at different rates (0%, 1%, 1.6%, 2.2% and 2.8% w/w) soil evaluated 10 20 weeks after treatment. Representative samples were incubated for 42 days microbial respiration determined. During first seven in...
