High installation
At high installation is a construction method that in the repair and renovation of roads is used. In this case, the incorporation of takes place concrete (single layer), or asphalt (one or more layers) on an existing road pavement, so that the roadway heights by incorporation of at least 4 cm above the stock. The process differs from deep paving , in which the existing pavement is either partially or completely replaced and the roadway heights remain essentially unchanged.
Compared with deep installation, the costs for high installation are lower, as the construction time is shorter and no material has to be removed and disposed of. However, the construction method is only suitable if the existing pavement is sufficiently stable. In addition, it must be noted that increasing the carriageway reduces the clearance height, for example in tunnels or under bridge structures, and road installations such as caps and shafts or the side shoulders must be raised.
