The parking lot above the Wurm or the concrete box profile in which the Wurm runs was built in 2009. Due to the flooding in 2021, the entire area was flooded and a lot of water entered the bedding layer In the meantime, the paved surface is no longer fit for use and there are constant risks of accidents due to heaving of the paved surface. Various sections have already been repaired by the municipal building yard. Various sections have already been provisionally repaired with asphalt by the municipal building yard. By renewing the parking lot surface with asphalt or embossed asphalt, the suitability for use is to be restored. The asphalt structure chosen is intended to prevent surface water from penetrating the surface, and the existing paving and the provisionally laid asphalt must be completely removed. Partial quantities of the paving are to be stored on pallets in consultation with the civil engineering office. The rest of the rubble is to be disposed of. By removing the paving stones and the bedding layer, an available layer thickness of approx. 12-16 cm is available and the new structure is to be produced as follows: Asphalt binder course AC 16 BS 30/45 10-14 cm, embossed asphalt 2 cm, asphalt layer 2 cm.
