Mixing and compaction temperatures for Superpave mixes ...

The use of shear rates experienced by the binders during compaction led to reasonable mixing and compaction temperatures for hot mix asphalt with modified asphalt binders. The application of the shear rate concept rather than the traditional approach used for unmodified binders can reduce the mixing and compaction temperatures between nearly 10 ...

What is Superpave? All You Need to Know - Gilson Co.

Compared to the Marshall design method, Superpave integrates material selection and mix design and uses an entirely different type of compaction. Instead of the impact of weighted hammer blows, the Superpave gyratory compactor (SGC) uses a hydraulically powered kneading system with an action much closer to the actual field densification of the mix.
