The cracking resistance of asphalt mixtures is changing due to the use of high-flow-resistant asphalt and recycled aggregates. Therefore, a universal test method was deemed necessary to investigate quality fluctuations in plants. Thus, this study aimed to propose a general-purpose crack resistance test method using 100 mm specimens based on the SCB test. The experimental results showed that a specimen with a diameter of 100 mm could be used for evaluation, based on a comparison with a specimen with a diameter of 150 mm and a discussion of the fracture process in the SCB test. In addition, based on the experimental results for each test condition, it was shown that it is desirable to use a specimen with a diameter of 100 mm, a movable fulcrum, a notch depth of 10 mm and a storage temperature of 20 °C or less.
