Asphalt mixtures

We produce a wide range of asphalt mixes for road construction or industrial platforms.

With the help of the AMMANN asphalt mixture preparation station, having a capacity of 160 tons/hour, we produce a wide range of asphalt mixtures for road construction or industrial platforms, with the following destinations:

Base layer: AB 31.5, ABPC 31.5
Connecting layer: BAD 20, BADPC 20, BADPS 20, BAD 22.4, BADPC 22.4, BADPS 22.4
Wear layer: BA8, BA16, BAPC16, MAS 16.
Asphalt mixtures with modified bitumen
