N2 - The PSV test has been used for many years. It is the harmonised European standard method for predicting an aggregates polishing resistance. This paper considers the test tyre / test specimen interface. This was done by painting the PSV test specimen surface and subjecting it to a period of accelerated polishing. Digital images of the test specimen were analysed using 2d and 3d techniques. Tyre / aggregate contact area was found to range from 17 % to 92 % of the test specimen area. Factors such as particle shape (convex, concave, flat) and particle orientation in the test specimen influence contact. The contact interface relates to the uppermost 1 to 2 mm of the test specimen surface. A weak relationship was found showing contact area to increase as wet skid resistance decreased. Whilst aggregate micro-texture remains an important factor the research suggests addi-tional scales of texture and contact influence water films at the interface. The findings of this paper impact attempts to measure road skid resistance using non-contact methods of measurement.
