Debris Mixed With The Fill Subgrade Compaction Quality Indoor Pilot Study

This paper analyses the origin cause of formation, formation mechanism of the intensity, classification and existing problem of mixing of the material of the soil and rock form. On the basis, through the test by the large-scale compaction instrument, this paper studies densification characteristic of the soil rock mixture and analyses the impact on the maximum grain , the grading analysis ,compaction work, the method of compaction and equivalent treatment of the maximum dry density and the optimum moisture content of the soil rock mixture. Meanwhile, it draws that the corresponding relation between the pressure and pass through into the bury depth and the different compacting factor and the different percent of gravel of soil-aggregate mixture through the pouring experiment under indoors different conditions.
