Hi Fathima, DevilAVRT gives a descriptive answer.
For understanding the concept,
DCT-Dynamic Cone Penetration Test is a penetration test used to determine the consistency, molecular attractions, and strength of the soil. It is a recommendation of AS1218.104.22.168. and AS1222.214.171.124
CBR – California Bearing Ratio test is a bearing test to determine it’s resistant for the applied load. This test is developed by the California Division of the highway.
Difference between DPC and CBR test:
Here, some important differences between DPC and CBR test are listed below;
(Also refer the above diagram for a clear understanding of the above concept)
Dynamic Cone Penetration testing
DCP testing is utilized to decide the quality of the subsurface and configuration heap of the dirt. The designers play out the testing in-situ to give an estimation of the heap bearing limit which a clay can withstand, by estimating the degree of infiltration into the ground of an aligned tip or cone. Stiffer soils will yield a lower infiltration rate while gentler soils will bring about the expanded entrance.
When the most extreme structure heap of dirt is known, these outcomes can be utilized to figure-fitting footings and establishments for sub/superstructures to be put on or inside the dirt. All DCP tests are performed by ADE’s group of geotechnical designs and agree to AS12126.96.36.199 and AS12188.8.131.52.
Californian Bearing Ratio testing
CBR testing is led to decide the quality of a material (normally a subgrade) when it is at its greatest compaction. This reason for this is to decide the necessary thickness of a basic layer or asphaltic layer (for example, a pathway) to be put on the head of the tried material. This test guarantees that the quality necessities sketched out by the extent of works are fulfilled.
To play out this test, the greatest dry thickness is required to be embraced on the preceding material testing to decide the remolded thickness of the example. The example is normally remolded at 100% of standard compaction (or the relative compaction accomplished nearby) to decide the quality of the material. This test will require the time taken for a most extreme dry thickness to be embraced, and afterward, a multi-day drench to decide the reactivity of the dirt preceding testing.
This worth is given as a rate when contrasted with a normalized material (California Limestone) where a low worth relates to powerless fill and a high incentive to solid filling.
