Abstract
A device for simulating the various forces a load of hot asphalt mix places on the inside of a gyratory compactor allows the calibration of the compactor without requiring actual asphalt to be used. Obviating the need for asphalt during calibration significantly increases the accuracy of the calibration and provides an opportunity for more data to be obtained. The device is capable of being heated to hot asphalt temperatures for more accurate calibration.
