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. This combination was first proposed by the British Road Research Laboratory in 1959 and such treatments have been in commercial use in the U.K. and several other countries for up to 9 years. Methods of application and the performance of such systems are described. For heavily trafficked but less critical roads, improved methods of conventional bituminous surface dressing are discussed, the most promising systems being based on the use of high-viscosity cutback with precoated chippings and a polymer/bitumen emulsion with hot chippings. Methods of adapting open-textured asphalt carpets, or friction courses, already well-proven on airfield runways, to heavily trafficked roads and city streets with their more intense and channelised traffic, are also discussed. Finally the paper discusses possibilities of alternative treatments such as those based on improved slurry seal formulations. /Author/
