Abstract
When dried granular material is subjected to saturation, depending on its properties and stress distribution in the soil mass, collapse settlement may occur due to sliding along grain contacts, particle rearrangement and their breakage. Collapse settlement is particularly important in the upstream side of clay core embankment dams during first filling and in road embankment if it is inundated. In this research, the effects of saturation on the shear strength parameters and collapse behaviour of a type of gravelly material are investigated via medium-scale direct shear test apparatus. Collapse tests were conducted by using direct shear test on the initially dry samples, which were flooded during shearing in the specific shear stress level. Tests have been done on sub-angular and angular shape aggregates with the same origin, gradation curve and specific gravity. It is shown that samples with sub-angular particles have more strength and less collapse settlement than samples with angular particles, although both types have the same relative density.
