| Typical use(s): |
Material required: |
|
|
Undisturbed:
- Enough intact material to trim down to a 300mm square by 150mm high block for each specimen required.
(usually block
samples, well wrapped, padded, and packed in a stout wooden
box or crate)
Remoulded:
- Approximately 30kg of <20mm material per specimen.
Note: If the particles are weak and break down during testing
(such as weathered sandstone or crushed concrete), then
fresh material must be used for each specimen, requiring
around 90kg for a set of 3 specimens. If material
is available in limited quantities but can be re-used without degradation for subsequent
specimens, then 40kg will be sufficient for a set of 3 but will
significantly increase turnaround times due to drying/wetting
times between specimens.

Immediate shear strength by rapid direct shear
(BS1377 : Part 7
: Clause 5 : 1990) and (Specification for Highway Works Vol.1 Clause
636 Part 2)
Note: only suitable for free-draining,
rapidly-consolidating material. If the material is not free-draining
and consequently consolidates slowly, then the test is carried out
as a drained test and is likely to incur additional extra over
day charges. |
£ 100.00 per specimen |
