The Experience with Wehner/Schulze Procedure in the Czech Republic

The paper presents the skid resistance measurements results achieved by Wehner/Schulze method; Christian Doppler Laboratory (TU Vienna) testing device was used.The Wehner/Schulze testing device is designed to simulate the polishing action of vehicles on road surfaces.The paper shows a wide scope of W/S method usage: evaluation of polishing of different aggregate fractions, laboratory prepared test specimens and specimens cored from pavements. More testing cycles can predict the long-term development of wearing course friction coefficient.
