An Asphalt Plug Joint (APJ) produced by Koch was physically tested in a pilot study sponsored by the Wyoming Department of Transportation at the University of Wyoming. An APJ was built, instrumented, and cycled to simulate 10 years of service for spring, fall, summer and winter conditions. A crack occurred during the winter cycling and was repaired. The joint was then tested until failure. Failure occurred as a joint material separated from the joint edge. The joint motion was concentrated between the bridging plate and the joint end. The APJ material exhibited both visco-elastic behavior and a brittle transition temperature in the operating temperature range. The pilot study is being extended to further investigate the nature of the joint and the material.
