In spring 2017, Colas Austria together with CST (Cold laid materials) developed a high modified bituminous emulsion for the Austrian surface dressings market.
With this new rapid breaking bituminous emulsion COLFLEX ULTRA, we can offer a higher cohesion and adhesivity and a better elastic behavior. This emulsioncan extend the lifetime of the surface, be applied in heavy traffic roads, increases the resistance to cracking and prevents bleeding in the hot summer time.
In summer 2017, more than 30.000 m² of single surface dressings have been made in Lower Austria in Franzendorf, Glinzendorf, in the town Traiskirchen and in the communities Pitten and Gmünd. In Styria we made 7.000 m² single surface dressings in Schäffern.
