Roller compacted concrete (RCC) is a cement concrete pavement laid with an asphalt paver and compacted with a vibrating roller. The principal applications so far have consisted of industrial platforms, paved areas in harbours and storage areas. The aim of the experiment was to test roller compacted concrete on a low volume road used by heavy vehicles and to follow the results over a number of years in regard to evenness, friction and cracking. The roller compacted concrete pavement, which is 180 mm thick, was laid with a high-compaction asphalt paver. Final compaction was performed with a vibrating roller equipped with rubber-treaded rollers. The finished pavement was inspected with regard to friction, evenness and cracking. The measured mean friction was good, with a friction value of over 0.70. However, the pavement became somewhat uneven. On the other hand it should be possible to set somewhat lower evenness specifications on low volume roads with low traffic speeds. No major damage has been observed when inspecting the pavement. Observation of the test road will continue over a number of years. The test shows that roller compacted concrete is a new and interesting alternative for use on low volume roads with low traffic speeds.
