      abstract     = {When a rubber block is squeezed against a nominal flat but
                      rough surface, the rubber bottom surface will penetrate into
                      the substrate roughness profile. The relation between
                      penetration depth w (or the average interfacial separation
                      ˉu) and the applied squeezing pressure p determines the
                      (perpendicular) contact stiffness K=dp/dw=−dp/dˉu, which
                      is important for many applications. We have measured the
                      relation between p and ˉu for a rubber block squeezed
                      against 28 different concrete and asphalt road surfaces. We
                      find a linear relation between logp and ˉu, in agreement
                      with theory predictions. The measured stiffness values
                      correlate rather well with the theory prediction},
