ABSTRACT:
The disclosed machine is comprised of a chassis, process control box and load wheel assembly. The chassis is designed to attach to commercially available controlled temperature heating baths. The primary functions of the process control box are to distribute electrical power, monitor sensor responses to electrical inputs, and to control the overall operation of the load wheel assembly. The load wheel assembly applies multiple load applications while not rolling off the surface of a standard asphalt concrete specimen.
