通过与劈裂强度试验、冻融劈裂试验进行对比,对MIST试验方法进行了研究。分析了试验温度、养生时间及空隙率对MIST试验结果的影响。结果表明:MIST试验与冻融劈裂试验结果较为接近;提高试验温度可在一定程度上加速水损害;乳化沥青冷再生混合料应加强早期养生及防水处理,空隙率变化值与TSR负相关。MIST可快速评定乳化沥青冷再生混合料水稳性能。 By comparing with splitting strength test and freeze-thaw splitting test, the MIST test method was studied. The effects of test temperature, curing time and voidage on MIST test results were analyzed. The results showed that the results of MIST test and freeze-thaw splitting test were close to each other. Increasing test temperature could accelerate the water damage to a certain degree. The emulsified asphalt cold reclaimed mixture should strengthen the early regimen and water-repellent treatment, and the change of void fraction was negatively correlated with TSR. MIST can quickly assess the water stability of emulsified asphalt cold recycled mixture.
