Abstract: We briefly review the most important contact mechanic theories regarding the average separation between an elastic solid with a nominal flat surface and a hard solid with a randomly rough surface, as a function of the squeezing pressure. We present experimental results for a silicon rubber (PDMS) block, squeezed against two different road surfaces Finally we compare the theoretical predictions of the different theories with the experimental data (C) 2009 Elsevier B V All rights reserved
