You can see a picture of the road widths of the federal roads; to the right and left of the picture are many green trees; in the centre the road is being renovated with 6 road construction machines.

Energy and CO2 were saved by using low-temperature asphalt in a conventional and compact design.

Low temperature asphalt.

Low-temperature asphalt, also known as temperature-reduced asphalt, is an innovative road construction material. Compared to conventional hot asphalt, this asphalt is produced and processed at significantly lower temperatures, up to 30°C less. The main advantages are considerable energy savings and a reduction in emissions, especially CO₂. In addition, this asphalt reduces the formation of vapours and aerosols during paving, which benefits both the environment and the health of workers.
