This paper considers problems on the rolling of rigid 
driven and driving cylinders slipping on a compactible viscoelastic 
base. As a result of the investigation of the process of propagation 
of viscoelastic decaying strain waves in a deformable medium caused 
by a cylinder rolling over it and the action of the sliding friction 
forces, formulas and calculation algorithms have been obtained for 
determining the indices of the stressed-strained state and compactness 
of the base, the rolling resistance of the driven and diving cylinders, 
and the driving force of the driving cylinder. Calculations of these 
indices have been performed for the cases of cylinders rolling over 
a soil whose viscoelastic properties have been investigated experimentally.
