Abstract

The use of a bitumen-extended epoxy resin/calcined bauxite anti-skid surfacing has been demonstrated to be cost effective in reducing wet road skidding accidents. Over 1 million square metres of this type of surfacing have now been laid throughout the world. The excellent performance of the treatment results from the use of calcined bauxite aggregate, having high resistance to polishing and abrasion, bonded firmly to the road surface with a thermosetting resin, which prevents rolling or embedment. From the Contractor's point of view the material needs to be laid under carefully controlled conditions and this is achieved by the use of purpose built machinery designed to give precise proportioning and distribution of the components. The process has the advantage of fast application and does not require modification to existing markings or street furniture. With careful planning the contract can be carried out with minimum disruption to traffic flow. Different techniques are needed to achieve optimum adhesion to varying substrates which can be asphalt, concrete or steel. The paper illustrates the different types of traffic situation which can be successfully treated, including junctions, pedestrian crossings, bridges, tunnels, and rumble areas.
