Roller-compacted concrete pavements in Norway
This report contains a paper which was prepared for the seventh international conference of the bearing capacity of roads, railways and airfields in Trondheim, June 2005 and supplied afterwards. Roller-compacted concrete, as the name suggests, is concrete that in its unhardened state will support a roller while being compacted. During the period 1985 - 1995 a total of 68 km of concrete roads was constructed in Norway using this method, of which almost 60 km was in tunnels. The annual average daily traffic (AADT) on these stretches ranges from 200 to 10 000 vehicles per day, the majority having low traffic volumes. By 2005, almost 15 km of these concrete roads will have been paved over with asphalt. The remaining 53 km are located almost entirely in tunnels or on bridges.
