Abstract: 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.

Abstract: 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.

Abstract: A system for evaluating properties of an asphalt sample includes a load frame and a test fixture. The load frame includes a platform and a loading rod. The test fixture includes: a base configured to rest on the platform of the load frame; first and second spaced apart vertical guide bars extending upwardly from the base; a horizontal cross bar above the base and extending between the first and second guide bars, wherein the asphalt sample is configured to be held between the base and the cross bar; a load plate above the cross bar, the load plate configured to receive the loading rod of the load frame to apply a load to the asphalt sample; a load cell above the base and configured to measure the applied load and to generate corresponding load electrical signals; and a controller configured to receive the load electrical signals.

Abstract: A two chip network adapter is used to implement offloaded networking tasks. The first chip is the main ethernet controller chip. The second chip implements the offloaded tasks. Communication between a host and the second chip is done by adding offload and completion tags to the ethernet frame header of frames associated with the offloaded networking task.
