Superpave Gyratory Compactors
Superpave Gyratory Compactors meet ASTM and AASHTO requirements for compacting hot-mix asphalt specimens for Superpave mix design procedures. Cylindrical molds are filled with asphalt samples and gyrated at a fixed angle and pressure. The two models offered by Gilson have unique features tailored to your application and budget.
