Abstract:: CMV is an indieator of continuous compaelion eontrol (CCC). The major purpose of the paper is toinvestigate the probability models of CMV and find the optimal rolled times based on the data of a subgradesite. Several methods were used to filter the CMV data and the diserete probability was used to find the mostaeeurate probability model. After analyzing the final CMV data, the results shows that the lognormal distribu-tion is the most aeeurate distribution. Based on the model, the result of optimal rolled times was found as sixlimes. The result of the paper provide a referenee for the subgrade continuous compaction.
