  • Patent number: 4972719
    Abstract: A test fixture to expedite the testing of the resiliency of cylindrical samples including asphalt materials. The test fixture includes a frame assembly having opposed side members for engaging the curved surface of the sample whereupon at least one transducer detects changes in displacement between the side members upon diametric deflection of the sample. Additionally, or alternatively, the test fixture includes a retaining mechanism and positioning mechanism. Upon initial alignment of the test fixture, the positioning mechanism thereafter provided automatic alignment of each consecutively tested sample with the force-applying axis. The remaining mechanism provides automatic alignment and engagement of the frame assembly with each consecutive sample.
