1.1 The purpose of this document is to describe how

the provision of appropriate levels of skid resistance on

in-service UK Trunk Roads, i.e. motorways and allpurpose

trunk roads, will be managed. This document

describes 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 necessary to deliver

the required skid resistance properties.
