This is an initial report of an experiment dealing with the use of expanded metal mats placed between the binder and surface courses of a Class I bituminous pavement at a location where a bituminous pavement of different design had shoved under heavy traffic. The purpose of the mats, of course, was to integrate the pavement in both longitudinal and transverse directions; the theory being that a small portion of the pavement, when subjected to a force that would ordinarily cause shoving, could actuelly shove only if an entire section of the embedded mat could be moved by that force. The purpose of the experiment, then, is to determine whether a group of such mats of certain design and placed in a certain way will provide extraordinary stability and prevent displacement of the bituminous pavement
