SHELLGRIP: A MAJOR CONTRIBUTION TOWARDS REDUCING ROAD ACCIDENTS

In order to obtain good wet road skidding resistance, a flexible pavement must have a minimum harsh micro tecture to ensure resistance at low speeds and a rough macro texture for resistance at high speeds. Penetration of a water film can only be achieved if there is sufficient micro texture in the road aggregate. Statistics show that 75% of road accidents occur in urban situations within 20 yd of junctions and pedestrian crossings due to the effect of polishing of the road surface by vehicle wheels. It was to solve this problem that shellgrip surface dressing of epoxy resin and bauxite aggregate was developed by the glc and TRRL and has been used worldwide since 1967. Tables presented in the article give "before-and-after" accident statistics which show the effect of shellgrip in reducing accidents. It is concluded that although the value of shellgrip and similar materials is proven, the actual amount spent in the UK is a fraction of the need. (TRRL)
