A method for quality testing asphalt includes: directing light from a light source to at least one surface of asphalt; detecting light reflected or refracted from the at least one surface of the asphalt using a light detector; and assigning a number indicating the quality of the asphalt in response to detecting light reflected or refracted from the at least one surface of the asphalt.

Systems and methods for quality testing of asphalt by predicting an indirect tensile strength ratio of the asphalt sample based on the binder loss value

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.
