Paving and Compacting with Low Temperature, Low Emissions Asphalt - Tunnel Kriegsstrasse, Karlsruhe

ongoing

The paving of a road tunnel under the Kriegstrasse in Karlsruhe was carried out under stringent constraints to reduce emissions. The contractor used machines with diesel particulate filters and low-temperature asphalts. The project involved the redesign of the area around Kriegsstrasse in downtown Karlsruhe, including the construction of a subway line and rerouting auto traffic into a tunnel. The project required the use of low-temperature asphalts to reduce exposure to fumes, emissions, and heat.
