摘　　要：通过对OGFC混合料的水稳定性的各种试验结果进行比较,发现残留稳定度和冻融劈裂比的试验结果同浸水飞散的试验结果得到的结论是有很大出入的;通过水损坏试验条件的交换,比较不同浸水条件下的稳定度和劈裂值,可以看出,对于OGFC混合料来说,马歇尔稳定度的绝对值本身就比较低,所以其残留比的参考性不大;通过OGFC混合料水稳定性各种试验方式的比较,可以说,以上3种试验都无法反映OGFC混合料实际路面的水稳定性情况,尤其是前两种评价方式,因此,在OGFC混合料设计过程中,浸水马歇尔试验和冻融劈裂试验是不必要的。Through the comparison to each kind of test of the OGFC blend＇s water stable results,discovered the test results have very big discrepancy;Through the exchange of different tests condition and comparing with the different immersion condition,may see,regarding the OGFC blend,Marshall stability＇s absolute value itself is quite low,therefore the significance of the ratio is not big.Mixture of water through the OGFC stability comparison of various test methods can be said that the above three kinds of tests can not reflect the actual water stability of OGFC mixture road,particularly the former two kinds of evaluation methods,so in OGFC Mixture Design process,the Marshall immersion test and freeze-thaw splitting test was unnecessary.
