Strict conditions for paving in the auto tunnel under Karlsruhe's Kriegsstrasse: To reduce emissions, the Schleith-Züblin consortium was allowed to use only construction equipment fitted with diesel particulate filters (DPF), and required to use low-temperature asphalt (LTA).
As proven team players, the Vögele pavers and Hamm tandem rollers met all the requirements as well as delivering efficient, high-quality paving.
Downtown Karlsruhe has been undergoing complete reconstruction in the Kriegsstrasse area since 2019. The existing wide through highway is being transformed with a landscaped streetcar line, avenues of trees, bike lanes, and plenty of space for pedestrians. A subway line is also being built, with through auto traffic being rerouted into a mile-long tunnel.
