Experience over the last 30 years in the UK has shown these surfacings to be highly effective in reducing traffic accidents on sites with high traffic density and skidding risk. Typical sites are the approaches to signal
controlled junctions, to roundabouts and pedestrian crossings subject to a heavy flow of vehicles. For the length of high friction surfacing necessary, reference should be made to Table 3.1 HD 36 (DMRB 7.5.1) and accompanying notes.

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

The paper discusses various types of skid-resistant treatment appropriate for different categories of road. For particularly critical areas such as junctions in cities, treatments based on epoxy resin binders and calcined bauxite have proved highly effective in maintaining skid-resistance and reducing accidents.

Over the years, ATSSA has demonstrated that the installation or upgrade of roadway safety features – many of them available at low-cost – can provide immediate and substantial safety benefits for all. The expertise, knowledge and experience of ATSSA members are in the development and installation of traffic control devices and roadside safety features that make the roadway safer and more forgiving for all users of the roadway system. This document (in large part) focuses on the policies and practices needed to move America Toward Zero Deaths (TZD).

The Federal Highway Administration (FHWA) is improving its process for issuing Federal-aid eligibility letters for roadside safety hardware systems. The FHWA's Federal-aid eligibility letters are provided as a service to the States and are not a requirement for roadside safety hardware to be eligible for Federal-aid reimbursement.
