A load and motion measurement system for use with a Hamburg Wheel Tracker device includes: a housing; at least one load cell held in or by the housing; a load platform held in or by the housing and resting on the at least one load cell; and a controller operatively associated with the at least one load cell. The load and motion measurement system is configured to be received in a sample tray that is held in the Hamburg Wheel Tracker device. The controller is configured to determine operational parameters associated with a wheel of the Hamburg Wheel Tracking device that rolls along the load platform. Vertical displacement measurement calibration and verification systems for use with a Hamburg Wheel Tracker device are also described, as are associated kits and methods.

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.
