Material required: |
- Long-term slope stability
- Foundation design
|
Undisturbed:
- sample with a core length
of about 2:1 length:dia ratio of full diameter, intact material
(ideally at least 2.5:1 length:dia
to allow for trimming)
- block sample twice the size of 2:1 length:dia sample required.
Remoulded:
- 200g of <6mm material for 38mm dia. specimen
- 4kg of <20mm material for 100mm specimen.

| Notes: |
| Caution: With fine-grained low permeability materials this test can have a long duration (eg. 1-2 weeks per stage) and correspondingly high charges due to the extra over
days incurred. In this case, if there is nothing larger than fine gravel, a set of three 38mm diameter samples may work out less expensive than a multistage 100mm diameter specimen and will have a much quicker turnaround (typically within 2 weeks). |
