|Hot Mix Asphalt||Cold Mix Asphalt / Bitumen Emulsions|
|Modifications of hot mix asphalt with Butonal® polymers improve resistance to rutting at high temperatures, reduce susceptibility to cracking at low temperatures, and extend the life of the road surface. Butonal® polymers are easy
to mix and use and can be directly added to the bitumen with a foam module and to the finished mix in the pugmill.
|BASF Butonal® polymers have set new performance standards in these processes, as they have a fast, long-term effect, are easily dispersed in bitumen emulsions, and can optionally be injected during the colloid grinding process or directly into the bitumen.|
