摘要：

Aiming at the deficiency of the water stability evaluation index of bituminous mixtures by immersion Marshall test in present specifications in china, the water stability of various of bituminous mixtures test pieces was analyzed by comparing freeze-thaw splitting tensile tests with immersion Marshall stability tests. There is larger difference between the evaluation results of immersion Marshall test and freeze-thaw splitting tensile test. The residual stability by immersion Marshall test is rarely inconsistent with regulatory requirements, Residual modulus is brought up to evaluate the water stability of bituminous mixtures. Residual modulus suggested to evaluate the water stability of asphalt mixtures has the similar trend with freeze-thaw splitting tensile strength ratio and the residual modulus threshold valve 0.85 is recommended.
