Abstract

Any traction failure during high speed operations of automobiles may lead to fatal accidents. Therefore, it is very important to understand tire and pavement interaction. It is assumed that at high speed the hysteretic or bulk internal friction of tire predominantly accounts for tire-road friction. Hysteretic friction reflects the energy losses that occur as the rubber is alternately compressed and expanded as it slides or rolls over an irregular pavement surface texture. Inevitably, when energy dissipation takes place, temperature develops in the tire rubber. The fundamental temperature dependence of viscoelastic properties of tire rubber has a significant influence on its hysteretic friction. Nowadays, researchers have developed Finite Element (FE) and Analytical models to study the tire and pavement interaction. Several analytical and numerical models use rheological material properties to develop such models. The Dynamic Shear Rheometer (DSR) has proved to be worthy to determine the rheological properties of asphalt binders which is widely available. However, authors feel that not much attention has been paid to investigate if the DSR equipment could be used to determine rubber rheological properties. The current paper aims to present a simple procedure to test tire tread rubber by using the DSR apparatus. A complete procedure including sample preparation from the tire, their optimal dimensions of samples and their testing methodology is presented in this paper.
