While a new tire may have excellent resistance to crack initiation and propagation between the steel belts, an aged tire of the exact same construction can exhibit dramatically reduced crack growth resistance, which in some cases may contribute to tire failure. This article will review the research that has gone into quantifying the rate of oxidation the steel belt rubber oxidizes in different ...

─ In a tire pressure monitoring system in which a pressure censor and a transmit antenna are contained in a tire, electromagnetic simulations of radiations from carcass embedded tires are requested. However, it is difficult to accurately determine these shielding effects. In this study, methods for performing accurate electromagnetic simulation by adopting the MoM scheme are determined. In the ...

2 Executive Summary The purpose of this paper is to familiarize the reader with the paving material asphalt-rubber (A-R) by providing historical perspective on its development and obstacles to its development. A-R has been a constant and stable market for crumb rubber producers in the United States most significantly within the vicinity of Arizona, California, and Florida. Agencies use A-R beca...

The development of environmentally accepted methods of used tire disposal is one of the greatest challenges that waste management experts face today. Use of waste rubber particles as aggregate in self-compacting concrete is a suitable solution for the environmental hazards of waste tires being produced on a large scale. The aim of this work is to investigate the influence of the size of waste r...

The viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with energy saving. The transient dynamic analysis for including the rolling effects of the tire requires long CPU time and the obtained results are ...

In any type of rubber product manufacturing (including tires), the primary concerns are environmental. The aim of the present study was to survey a treatment combination of ozonation and physicochemical processes in the rubber industry. Wastewater samples were collected from the discharge unit of the rubber processing sewage system in Kerman Barez Tire Factory, Kerman, Iran. The wastewater samp...

The 20-40mm particle size of crushed aggregate and rubber aggregate showed 100% passing but river sand showed zero%. The 10 mm particle size of river sand showed 100% passing. Hydraulic conductivity ranges from 0.5 cm/sec (0.2 inches/sec) for compressed 10–38 mm (0.4–1.5 inches) shreds to more than 20 cm/sec (8 inches/sec) for 25–64 mm (1– 2.5 inches) loose shred. Thermal conductivity varies fr...

coeffcient of  friction  (cof)  for  rubber parts  is one of  the key parameters in their interaction with solid rough surfaces (micrometer to millimeter scales),  such  as  tire-road  interactions. cof  of  rubber  depends  on  viscoelastic properties of rubber, roughness characteristics of the counter-part surface, and process variables such as contact nominal pressure and sliding speed. due ...

After 1860’s the railway systems has started to be used in urban transportation in the world. However, especially after the 1950’s, automobile usage has been increased quickly. Thus the dense of transportation has started to move from railway systems to the ones with rubber tire vehicles in Istanbul. Traffic density in urban transportation has started to be experienced since 1950 with the incre...
