- Abstract
Metamorphci phyllite is fragile, the gradation show large variation. Different pressure levels are selected at first to make sure the stable gradation. The test results show that 600 kPa pressure level meets the requirement and metamorphic under this level is choose for further compaction analysis. Compaction tests are carried out based on different pressure levels, in order to make the comparison of grain breakage at different pressure level and eliminate the low pressure level grain breakage influence. Interior california bearing ratio (CBR) tests are carried based on the reliable pressure level, too. The results show that the maximum dry density and optimum mositure content are changing together with different pressure levels, for our project, the reliable maximum dry density is 2.46 g/cm3 and correspond to optimum mositure content is 5.4% with the sample of pressure level of 600 kPa. CBR tests based on the reliable pressure level meets the requiement of embankment filling standard, which gurantees the safety of the project using metamorphic phyllite in the view of embankment compaction construction.
