in this study an empirical model which can be used to predict the rutting parameter (g*/sinδ) for neat and powder rubber modified bitumen describes. the model was developed using 36 unique powder rubber modified bitumen combinations, rubber concentrations were varied at 5% intervals between 5 and 20%. the effects of powder rubber particle size on model accuracy were also studied ultimately a mo...

In this study, a styrene butadiene rubber, which is similar to the rubber used in road wheel backer pads of tracked vehicles, was investigated experimentally under monotonic and fatigue loading conditions. The monotonic loading response of the material was obtained under different stress states (compression and tension), strain rates (0.001/s to 3000/s), and temperatures (-5C to 50C). The exper...

Up-to-date predictive rubber friction models require viscoelastic modulus information; thus, the accurate representation of storage and loss components is fundamental. This study presents two separate empirical formulations for complex moduli materials such as rubber. The majority found in literature are based on tabulated dynamic testing data. A wide range experimentally obtained used this stu...
