Asphalt tester from ZORN : new technical standard ensures traffic clearance

Earlier traffic release of heavily trafficked roads is now possible without the known construction-related risks for both contracting parties. But also a safe traffic release during tropical nights and other circumstances can be determined with the Asphalt Tester by ZORN.

The working group of the Forschungsgesellschaft für Straßen- und Verkehrswesen (FGSV, Road and Transportation Research Association) created a binding, technical set of rules with the publication of the reference paper "Hinweise zur Verkehrsfreigabe von Verkehrsflächenbefestigungen aus Asphalt H VVA" (link reference paper, only in German). The Asphalt Tester required for the application of the reference paper was specially developed by us.

With this field tester (Asphalt Tester ZORN AT H VVA), the only one of its kind in the world, for assessing the safe trafficability of asphalt wearing courses, you can carry out regular tests in accordance with the specifications of the H VVA easily, quickly and safely!
