Description	Systematic study of a low-amplitude surface roughness passing through a rolling elastohydrodynamic contact has led to general model called amplitude attenuation theory. Under pure rolling the conditions in contact inlet controls the amplitude attenuation. Whereas, the situation in rolling-sliding contact is more complex, not only inlet but also conditions inside the contact are important to explain roughness behaviour. It was found that under high speeds and high sliding conditions thermal effects like inlet shear heating, viscosity wedge effects and others are significant. They influence conditions in the contact inlet and inside contact so that, it leads to change in film thickness distribution and pressure field. In this study, high speed high sliding conditions were applied to study a role of thermal effects on roughness behaviour. The results are compared with current state of knowledge in the field of amplitude attenuation principle.
