Compaction of unbound materials in road constructions (English)
Abstract [sv]

A number of roads have shortly after their construction had quality problems. The problems consisted of early rutting and cracking that result in increased maintenance costs. Despite heavy structures made of crushed rock, it has not been possible to avoid unfavourable quality development. According to the Swedish Transport Administration, these quality issues are particularly common if the subsoil consists of water-rich soils as silt and clay. The report aims to discuss the improvement and development of compaction of unbound materials in roads. In order to gather information and experience, a workshop was arranged with industry representatives with expertise in compaction. The basis for the contents in this report comes from the workshop and the discussions with the Swedish Transport Administration. The report also generally gives information about current Swedish compaction requirements and the most common methods to measure compaction quality.
