  • Systems and methods for maximum specific gravity tests for asphalt mixture samples
    Patent number: 10215678
    Abstract: A system for conducting a maximum specific gravity test includes a sealable container for receiving and holding an asphalt mixture sample, a vacuum pump in fluid communication with the container for evacuating the container, a valve in fluid communication with the container, a shaker for shaking the container, and a controller. The controller can operate the system in a test mode by: (i) turning on the vacuum pump; (ii) automatically monitoring a vacuum pressure in the container with the vacuum pump on; (iii) automatically turning on the shaker when the monitored vacuum pressure reaches a target vacuum pressure value; (iv) automatically opening or closing the valve such that the monitored vacuum pressure in the container is maintained within a target vacuum pressure range for a predetermined period of time with the shaker on; and (v) automatically turning the shaker off at the end of the predetermined period of time.
