The objective of this work is to compare the semi-circular bend (SCB) and disk-compact tension (DCT) fracture tests for asphalt-aggregate mixtures. Fracture tests are performed. Statistical analysis, digital image correlation, and 3D scans show that the SCB tests measure a low fracture resistance with a high coefficient of variation due to stress concentrations and plasticity developing at the anvil contact point. The DCT test is found to measure a high fracture resistance with a low coefficient of variation. The DCT tests is determined to provide a superior measurement of fracture resistance. Evidence concerning the physical problems with SCB is provided.
