Anthracite walls along the A1
Bosch Beton installed anthracite walls along the A1 motorway at Bathmen. Heijmans realised a sound barrier here contracted by Rijkswaterstaat and the Municipality of Deventer.
In the coming years, Rijkswaterstaat will be expanding the A1 between Apeldoorn and Azelo. To prevent noise nuisance at Bathmen, Heijmans realised a sound barrier contracted by Rijkswaterstaat and the Municipality of Deventer.
This sound barrier comprises two sound screens that are connected by an embankment. As a motorway gantry sign intersects the future embankment, this embankment could not be continued across the full width at the location of this gantry sign. Retaining walls were installed at the level of this gantry sign to create space and earth was backed up against the walls on the residents’ side, ensuring that the embankment continues on the residents’ side, but not on the roadside.
Special: anthracite walls
Four-metre-high retaining walls were used (LA400G). The walls needed to be anthracite in colour. We modified our mix especially for this project in accordance with the sample sent, as our own anthracite mix is darker in colour. Climbing plants will be placed along the wall so that it becomes part of the landscape.
As the wall along the motorway needed to be placed in a traffic system behind barriers, we investigated the construction site in advance and discussed the access route, parking area for the truck mounted crane and the requirements for the substructure. These preparations resulted in a short realisation time of 4.5 hours and minimised interruption to other construction traffic.
