Besseres Arbeitsklima im Strassenbau

Warmasphalt erzeugt weniger Emissionen

(PresseBox) (Dübendorf, )
Brütende Hitze, heisse Dämpfe und laute Maschinen – das Asphaltieren von Strassen ist ein Knochenjob. Empa-Forschende haben analysiert, ob und wie viel schädliche Emissionen entstehen, wenn regulärer «Heissasphalt» oder aber sogenannter Warmasphalt verlegt wird. Resultat: Der ökologischere Warmasphalt sticht auch in Sachen Emissionen die herkömmliche Methode aus.

Asphalt ist eine heisse Sache: Normalerweise wird er bei 160°C gemischt, transportiert und anschliessend von den Strassenbauern bei circa 150°C verlegt. Das ist nicht nur für die Arbeiter eine Belastung; auch der ökologische Fussabdruck von Asphalt ist aufgrund des hohen Energieverbrauchs und der daraus resultierenden CO2-Emissionen immens. Eine Lösung bietet der sogenannte Warmasphalt. Taeaoj pzac uxbhgzwmn dzi 771 cst 844qK foggjhp cot eyz nskb qiswgrlylwk Pccitadoeief fwpkvjz.
