Dynamic Cone Penetrometer
For determining the resistance of different soil strata to dynamic
penetration of a 50 mm cone and thereby obtain an indication regarding their
relative strengths or density or both. The method helps survey of large area
in a short time. In some cases, especially if the depth is great, it may be
difficult to pull out the cone after the completion of the test. Hence the
cone without threads should be used in the case of deep soundings as it may
be left in the ground. For shallow depths, generally upto 15 m, if the
conditions permit, the cone with threads may be used. It consist of :
IL - 511Cone Plain 50mm base dia and cone angle 60 deg.
IL - 511Cone adaptor with cone and standard threads for 'A' rod
coupling.
IL - 511Cone threaded for 'A' rod coupling 60 deg. cone angle, 50mm
base dia.
The CBR test is used for determining the relative
bearing ratio and expansion characteristics under known surcharge weights of
base, sub-base and sub grade soils for the design of roads, pavements and
runways. Tests can be conducted on all types of soils including sand, gravel
and washed stone (passing through 20 mm IS Sieve). The CBR test is used
extensively in selection of materials and control of sub grades. The
procedure consists of loading soil with a circular piston, 50 mm dia face
and maintaining a penetration rate of 1.25 mm/min. The load is noted and the
results of test on natural or recompacted soils, in soaked and unsoaked
conditions, can be compared with standard test results.

California Bearing Ratio Test Apparatus, Field Type
IS: 2720 (Part 31)
The use of the in-situ CBR apparatus on large road construction projects
has increased considerably in recent years. This apparatus, mounted on a
rolled steel joist cantilevered from the back of the truck or fitted to the
underside of a mobile frame, can be used to determine the bearing capacity
of soils quickly and efficiently. This method of testing in-situ, using
piston penetration, is useful for determining the load carrying capacity in
the field, when the in-place density and water contents are such that the
degree of saturation is 80 % or greater, when the material is coarse grained
and cohesion less so that it is not affected by changes in the water content
and when the material has been in place. It consists of :
Loading Jack : with U-bracket, capacity 50
kN (5,000 kgf). This is specially designed for use with Field CBR test
apparatus. It consists of a hand operated, two speed, screw jack fitted with
a U-bracket. A hexagonal adapter is provided to fix a proving ring. A thrust
bar, which passes through the U-bracket, is screwed on to a proving ring
(supplied at extra cost) which protects the proving ring when the loading is
eccentric.
Swivel Head : for the Loading Jack
Penetration Piston : 50 mm dia threaded at the upper end, to connect
to the various lengths of extension sleeves, through a connector
Extension Set : consisting of 1 length of 5 cm, 2 lengths of 10 cm,
1 length of 30 cm, 1 length of 50 cm and a length of 100 cm used as spacers
between the proving ring and penetration piston. The lengths are machined
from steel tubing
Connector Set : has eight connectors for coupling the penetration
piston and proving ring assembly, either directly or through extension
pieces
Datum Bar Assembly : consisting of two stands and 1 m long Bar
Adjustable Bracket : for mounting the Dial Gauge
Annular Metal Weight : 5 kg, 250 mm dia with 53 mm dia central hole
Slotted Metal Weight : 5 kg, 215 mm to 250 mm dia with 53 mm dia
slot, 2 Nos.
Slotted Metal Weight : 10 kg, 215 mm to 250 mm dia with 53 mm dia
slot, 2 Nos.
Optional Extra
» Dial Gauge: 0.01x25 mm
» Proving Ring: 50 kN (5,000kgf) capacity
Liquid Limit
The liquid limit, defined as the moisture content at
which the soil passes from the plastic state to the liquid state, is very
helpful in the classification of the potential properties of the soil
material. The liquid limit gives a measure of the shearing resistance which
a soil has when mixed with water. Casagrande Method or Cone Penetrometer
Method can determine the liquid limit of soil.
