  1. Base – the main load-bearing/load-spreading layer in the road structure and is usually 100mm, although can be thicker depending on the loading of the traffic for which the road is designed.

  3. Surface – the top layer of the ROAD  PAVEMENT and as such is (usually, but not always) designed to be impervious to the ingress of water, have an even RUNNING SURFACE, be durable, and have a high resistance to skidding and be chosen so as not to deform under the weight of traffic appropriate to the road.
