| Summary: | The residual soils are earthen formed of weathering process on rock and
remained at the place where it was formed.
Many studies were made to determine the
engineering properties of resi
dual soil in Malaysia but until now
in Sarawak
not
much data can be found for the
engineering properties of residual soil.
Thus, the
main objectives are to
determine index properties and to investigate on engineering
properties of residual soil in Kota Sam
arahan, Sarawak.
Varies of
physical and
engineering
properties
tests have been conducted for three samples
which taken from
three
different locations.
The three locations are for the Institut Latihan Perindustrian
Kota Samarahan, Vista Aman housing area, a
nd Samarahan Expressway near the
UiTM Samarahan roundabout represented with sample A, B and C respectively.
Experimental
results show
that the natural moisture content is in range of 22 to
32.3%. The specific gravity (G
s
) of the residual soil samples teste
d ranges from 2.65
to 2.67.
The liquid limit of the soil varies from 43 to 58%. Sample A has the lowest
value of liquid limit as compared to sample B and sample C. The Optimum Moisture
Content (OMC) and maximum dry density for residual soil are varying fro
m 20.0 to
26.5% and 1.47 to 1.60 Mg/m
3
, respectively. The value of compression index (C
c
)
and coefficient of consolidation (C
v
) for the residual soil vary from 0.133 to 0.232
and 2.314
to 6.941 m
2
/year
respectively. Then, the shear strength parameters, val
ue
of angle of internal friction (υ) vary from 10.94° to 17.14° and the cohesion (c) vary
from 8.83 to 18.64 kN/m
2
. Next, the initial void ratio (e) for the residual soil tested is
in a range of 0.786 to 1.0199. |
