Abstract: An apparatus for testing paving samples includes a base that includes a paving sample tray about the cabinet and configured for translation relative to the cabinet. A roller is configured for imparting compressive forces to a sample carried by the sample tray. An arm is configured for moving the roller from a stowed position to an in-use position where the roller contacts the sample. A cylinder assembly having a piston therein supplies pressure forces to the arm to move the arm from the stowed position to the in-use position, wherein a depth of travel of the arm is limited by the sample. As the sample is compressed, the depth of travel increases. A measurement device is in communication with the cylinder for determining an amount of travel of the arm to thus determine an amount of compression of the sample.
