3. STANDARD PENETRATION TEST
The Standard Penetration test (SPT) is a common in situ
testing method used to determine the geotechnical
engineering properties of subsurface soils. It is a simple and
inexpensive test to estimate the relative density of soils and
approximate shear strength parameters.

5. MOISTURE CONTENT TEST
• This method covers the laboratory determination of the moisture
content of a soil as a percentage of its oven-dried weight. The
method may be applied to fine, medium and coarse grained soils
for particle sizes from 2 mm to >10 mm.
• The method is based on removing soil moisture by oven-drying a
soil sample until the weight remains constant. The moisture
content (%) is calculated from the sample weight before and after
drying
𝜔 =
𝑀2 − 𝑀3
𝑀3 − 𝑀1
𝑀1= weight of tin (g) 𝑀2=weight of moist soil + tin (g) 𝑀3=weight of dried soil +tin (g)

6. DRY DENSITY TEST

7. MOISTURE & DRY DENSITY TEST
Density of three (03) samples was determined in accordance with the procedure described in ASTM D 7263-09.

8. Unconfined Compression Test
• The Unconfined Compression Test is a laboratory test
used to derive the Unconfirmed Compressive Strength
(UCS) of a rock specimen. Unconfirmed Compressive
Strength (UCS) stands for the maximum axial
compressive stress that a specimen can bear under zero
confining stress. Due to the fact that stress is applied
along the longitudinal axis, the Unconfined
Compression Test is also known as Uniaxial
Compression Test.
