One of the most common pavement distresses is related to surface cracking. Therefore, identifying and characterizing fracture properties of asphalt mixtures are significant towards a better pavement design. This study reviews four experimental methods used to determine the fracture energy in asphalt mixture. These methods include circular bending test (SCB), disc shape compact tension test, single-edge notched beam, and indirect tensile test. Each experimental method has its characteristics and advantages. These experimental methods are reviewed on the basis of their features, efficiency, and parameters measured. The coefficient of variation (COV) for the fracture tests reflects the result reliability of the test methods. Results with low COV value reflect low variance in the fracture test, whereas high COV indicates high variance. The review indicates that the SCB test is commonly used for determining the fracture energy in asphalt mixtures due to its simplicity and data reliability.
