Asphalt Paving at Swiss Mountain Tourist Hotspot
Because of its striking shape, the 2,362 m high Niesen in Switzerland is also known as the “Pyramid of the Alps”. In order to prepare the tourist hotspot for the summer season, the footpath between the summit station and the Berghaus Niesen Kulm hotel/restaurant had to be renovated. The 170 m footpath is used for transporting food and beverages to the summit hotel and is frequented by around 1,000 people every day in the high season. As the summit of the Niesen can only be reached by the funicular railway or helicopter, the construction site logistics were a major challenge. On top of this, the weather conditions were very difficult due to the altitude and the exposed location. The contractor opted for the MINI 500 paver from Vögele. The manufacturer’s smallest road paver model is predestined for applications where narrow paving widths, compact dimensions, low weight, and high paving quality are required. With a transport length of 2.6 m, a width of 0.9 m, and a weight of 1.4 t, the project team was able to transport the paver to the summit station on the Niesen funicular railway. The contractor hired a helicopter to keep the paver supplied with asphalt mix. This allowed the hot asphalt mix to be transported to the paver as quickly as possible. It took on loads of mix from insulated and heated trucks 700 m below the construction site and offloaded them directly into the material hopper of the MINI 500 at intervals of just under 4 min. Equipped with the AB 135 extending screed, including bolt-on extensions, the Vögele paver paved the 4 cm thick surface course over a width of 1.8 m - occasionally in several strips.
