Effects of initial particle gradation and rock content on ...

2020-4-1  For fills with 35% and 45% rock contents, there were more than 50% fine grains, in which coarse grains were absent to form the skeleton to resist the external load, leading the particles to break more easily. To sum up, with the increase of compaction time (from one to two), the effect of rock content on the degree of crushing was weakened.
