Abstract:

To determine the fracture characteristics of asphalt mixture, a novel fracture test with modified loading modes, loading fixtures and the control system of the conventional overlay tester is implemented by the asphalt material performance tester(AMPT). In order to evaluate the validity of the proposed fracture test, four different loading rates, including 1, 2, 3 and 4 mm/min, are examined in the AMPT. The results indicate that the fracture behavior is similar to creep at a low loading rate and does not show significant marginal tail extension at a high loading rate. It clearly shows the phase of crack initiation, crack propagation and fracture at a loading rate of 3 mm/min. Besides, eight fracture parameters, such as fracture energy, tensile strength and tensile modulus, are applied to evaluate the fracture characteristics of asphalt mixture. Development of the overlay tester for the fracture test of asphalt mixture can be considered as a new fracture test of asphalt mixture.
