Abstract:

The OT applies repeated direct tension loads to asphalt mixture specimens by fixing one side of the specimen to one block and allowing the other side to slide to apply tension in a cyclic triangular waveform to a constant maximum displacement of 0.025 inches. The result of the OT is an evaluation of the specimen’s critical fracture energy parameter and resistance index. Specimens are cut from a gyratory pill, with 7.0±1.0 percent air voids, and conditioned at the test temperature (77°F) for at least one hour before testing.
