High Friction Surfacing
Mark Stephenson, Head of Consultancy Services at W.D.M. Limited, gave delegates at the Road Surface Treatment Association seminar an insight into the research carried out on the effectiveness of high friction surfacing.
WDM® have measured the in-service sideway force coefficient, or wet skidding resistance of HFS, across the UK. The data collected supports the view that HFS provides the best long-term solution for achieving the necessary SCRIM® road survey machine values across the network particularly where a SCRIM® value above 0.5 is required i.e. on approaches to crossings, junctions and roundabouts.
