National Highways skid resistance requirements

National Highways skid resistance requirements

The latest version of CD534 (0.1.0), effective from May 2022, contains changes to Skid Resistance test requirements that are now based on a WRc test method for BS EN 124-conforming coarse textured cover surfaces. This method employs a pneumatic tyre traversing sideways across the cover surface in lieu of the former Pendulum Test method (which was considered susceptible to variations due to; coarse textured surfaces, datum location and operator skill).

However, the minimum >60 PSRV requirement for BS EN 124 products remains unchanged for all Group 4 applications.
