The New Spanish Standard on Pavement Design

Paper by ROECI KRAEMER from ISCR 6th 1990

The General Highway Plan (1984-1991) currently under execution has prompted an overall update of the specifications, in order to take into account the past experience, the new materials and the traffic evolution since 1975. In general, internally vibrated portland cement concrete pavements (PCCP) for heavy traffic have transverse joints every 5m with dowels and non-erodible bases of lean concrete or cement-treatedgravel.Continuously reinforced concrete pavements(CRCP) and roller-compacted concrete pavements.(RCC) with a bituminous surfacing are alsoconsidered.The specifications cover the materials used, thejoints, shoulders of concrete or other materials.
