Fire resistance requirements for rubber-tire warehouses

Rubber friction and tire dynamics.

We propose a simple rubber friction law, which can be used, for example, in models of tire (and vehicle) dynamics. The friction law is tested by comparing numerical results to the full rubber friction theory (Persson 2006 J. Phys.: Condens. Matter 18 7789). Good agreement is found between the two theories. We describe a two-dimensional (2D) tire model which combines the rubber friction model wi...

Reactive Processing of Silica-reinforced Tire Rubber

Requirements Engineering for Data Warehouses

Data Warehouses (DWs) aim at supporting the decision-making process of an organization. In the Requirements Engineering (RE) domain, several methods were proposed for the development of DWs, most of them based on the Goal-Oriented Requirements Engineering (GORE) approach. However, there is not yet a comprehensive and unified perspective of the various methods proposed. In this paper, a coherent...

Rubber Oxidation and Tire Aging - a Review

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 ...

Zinc leaching from tire crumb rubber.

Because tires contain approximately 1-2% zinc by weight, zinc leaching is an environmental concern associated with civil engineering applications of tire crumb rubber. An assessment of zinc leaching data from 14 studies in the published literature indicates that increasing zinc leaching is associated with lower pH and longer leaching times, but the data display a wide range of zinc concentratio...
