A laboratory model for experimental investigations of the rubber-asphalt sliding pair has been designed with the purpose of better understanding of dynamic behavior of the friction force in the contact patch between the car tire and the road. Its design is described and some experimental results are given. These results confirm that it is essential to use a dynamic friction model in order to describe friction force in contact between the car tire and the road. Moreover, they indicate that the existing dynamic friction models night be physically incorrect regarding the change of friction coefficient for an asperity bristle passing through the contact surface.
