Abstract: An apparatus for testing pavement test samples for for surface wear, including rutting, stripping and fatigue, is disclosed. The testing machine includes a testing chamber and a sample tray that is adapted for holding one or more test samples. The machine also includes a hose for each test sample to be tested. Each hose is disposed above a test sample in the sample tray in such fashion that the hose may be deflected to contact a least a substantial portion of the sample. A mechanism is also provided for pumping a fluid into each hose and for maintaining fluid pressure within the hose. The testing machine also includes a testing wheel assembly that is disposed above the hose assembly within the chamber. The testing wheel assembly is adapted for reciprocating movement on a track and includes a loading wheel for each hose.
