The surface of a road determines the speed of the traffic using it.

Modern vehicles with their air tyres and shock absorbers can easily deal with the odd bump in the road.

This was a different story during the days of the steam tractors.

   - a hexle to shred shrubs and trees growing alongside the road

   - a stone cutter transforming stones to road-metal

   - a caravan for the supervisor
