The serious damage of contact surfaces when being dynamically strained may only be resolved gradually, using an experimental analysis of samples taken from the contact- stressed areas. The paper deals with a new theoretical approach to the loading analysis of contact surfaces during rolling. Presented experimental part of the research is based on the laboratory testing, with use of the two new-type designed experimental devices. There was pointed out the necessity of experimental research, focused on the limit states of the material and presented consideration about thermal effects in the contact along the slip characteristics, which is described within the entire range on the basis of the probability theory.
