MIXING

The Superpave mix design requires the mixing of various sizes of aggregates with bitumen, additives and possibly other synthetic resins. The bituminous mixture is prepared at a target temperature within a time that is limited in order to reduce mechanical degradation of the aggregates. The target temperature depends on the grade of bitumen as well as on the type of mixture to be obtained.

Matest offers a wide range of Laboratory Mixers capable of coating all coarse and fine aggregates by controlling temperature and mixing speed.
