3606 PAV vacuum oven is designed for use in the degassing process of the binder material that has been removed from the Pressure Aging Vessel in accordance with AASHTO PP1-98. Immediately following the degassing process, the material can then be tested in the Bending Beam Rheometer, the Dynamic Shear Rheometer or the Direct Tension device. Degassing of the material prior to these tests insures that the material does not contain air bubbles. Entrapped air can compromise the integrity of the binder material, thus causing false failures in the previously mentioned test devices.
