Skid Resistance, Part 1: This Standard describes how the provision of appropriate levels of skid resistance for trunk roads will be managed. It details how measurements of skid resistance are to be made and interpreted and is complemented by HD 36 (DMRB 7.5.1), which sets out advice on surfacing material characteristics. This latest revision has changed requirements for setting investigatory levels, for annual SCRIM surveys, for determining the characteristic SCRIM coefficient and has further updates in line with current policy.
