HC Deb 08 July 1976 vol 914 c670W
Mr. Shepherd

asked the Secretary of State for the Environment what progress is being made by the Road Research Laboratory in the development of a design of cattle grid with a low skid risk and low noise factor when traversed by vehicles.

Mr. Marks

TRRL conducted relevant experiments in 1960 and found that coating cattle grids—amongst other things—with epoxy-resins considerably reduced the chances of skidding. No development work is currently in hand however.
