Characterization of recovery properties of asphalt mixtures

The CSR test and internal stress model innovated in this paper can be applied to any viscoelastic materials to determine their recovery properties. Because the CSR test has been validated in this study, the entire test procedure can be shortened to two steps including a nondestructive and a destructive CSR tests. Based on the results of the two CSR tests, the internal stress can be simulated using the exponential model developed in this paper, and the recovery modulus is then determined during the recovery phase of the material.
