dry density of recycled aggregate guinea

For coarsegrained soils with an existing dry density lower than the maximum dry density vibrations will result in the rearrangement of the soil grains The result is a reduction in void ratio and compressibility as well as an increase in the internal angle of friction Van Impe et al 1997Vibro compaction is the use of a depth vibrator to subject the ground to such vibrations resulting
