§ Mr. Pounder
asked the Minister of Transport what research is currently being conducted by his Department into further improvements in the development of nonskid road surfaces; and what progress is being made.
§ Mr. Swingler
On concrete surfaces, current research is concentrated on pro-clueing a durable deep surface texture. On bituminous surfaces, the materials used are an important factor, as well as the surface texture. Research into the characteristics of different road stones and hinders is continuing.
Studies of accident statistics have established standards of resistance to skidding for different locations and classes of road. Stretches of trial surface using different materials have been laid throughout the country to assess their value in relation to these standards. Full scale trials are now being planned on high speed roads near London.
