Coastal Protection With Fliegl Push-Off Technology
Coastal protection is a top priority, especially in times of increasing weather extremes. In Norddeich, the asphalt covering of the dyke was therefore renewed after it had been severely damaged by wind and waves for 30 years. Cracks and an insufficient surface weight made comprehensive renovation necessary. Tell Bau GmbH, led by site manager Kilian Efen, took on this challenging task and relied on the thermally insulated push-off trailer (Thermo ASW) from Fliegl Bau-und Kommunaltechnik.
Precise asphalting on challenging terrain
Over a distance of 3.9 kilometers, nine centimeters of the old asphalt was first milled off and then 18 centimeters of new asphalt was laid -a total of around 27,000 tones of material. The work was completed within 18 paving days.
The particular challenge lay in the slope of the embankment, which was ten degrees on the bottom layer and up to 23 degrees in places on the top layer. Conventional tipper semi-trailers would have been exposed to a high risk of tipping on this steeply sloping terrain. This is where Fliegl’s Thermo ASWs proved their worth: thanks to their innovative push-off technology, the transport trailers remained stable and enabled the asphalt to be unloaded in a safe and controlled manner.
Highest quality thanks to thermally insulated push-off technology
A key advantage of the push-off technique is that the asphalt material is fed into the paver in layers. This prevents thermal and mechanical segregation so that the asphalt can be laid homogeneously and at a uniform mixing temperature. This contributes significantly to the longevity of the new asphalt surface -a decisive factor for the long-term protection of the coastline.
The Thermo ASWsfrom Fliegl haveproven to be a reliable solution for this demanding application. They not only enable safe working on difficult terrain, but also ensure first-class asphalt quality, which makes the dyke resistant in the long term. The successful completion of this project proves once again that innovative technology can make a decisive contribution to modern coastal protection.
