C.B.R.Test Of Soil Complete Practical & Calculation |California Bearing Ratio Test By IS 2720 Part16

#cbrtestofsoil #completecbrtest # Californiabearingratiotest
#cbr_Test_of_Soil
The california bearing ratio test (CBR test) is defined as the ratio of the test load to the standard load, expressed as percentage for a given penetration of the plunger.
In this method the combination of load penetration test performed in the laboratory or in-situ along with empirical design charts are analysed to determine the thickness of pavement and its constituent layers.
For designing the flexible pavement this is one of the most commonly used method. The thickness of the various elements comprising a pavement is determined by CBR values.
The CBR test is a small scale penetration test in which a cylindrical plunger of 5 cm in diameter is used. Cross-section is penetrated into sub-grade material, at the rate of 0.05 in per minute i.e 1.25 mm/min.

Dear no of blows have been mentioned in IS 2720 p7,2720 P8.25 NOS IN BOTH CASE LIGHT/HEAVY.

Sir very good explanation. Load factor calculation I have not reached I should do practically then I could under stand

Thanks sir

[@ushagupta3204]

When it goes up it means compressive force is acting on proven force?

[@HIGHWAYENGINEERING]

Yes

Very nice work sirji... Only sitting load ka details batao pls..4 kg sitting load..

[@HIGHWAYENGINEERING]

Jab aap Mould Machine me fix karoge tab hum mould ko set karne ke liye plunger ko already itna Penetrat karenge ki mould pe load 4 kg aa jaye

Sir when we use heavy compaction and when light compaction?

[@HIGHWAYENGINEERING]

Written in specifications part 7 mean light part8 mean heavy

Sir, cbr swelling maximum how much.

Very good explanation and knowledge full

Sir did you get the MDD and OMC from modified Proctor test?

[@HIGHWAYENGINEERING]

kzbin.info/www/bejne/q2fTmoSglpl6j5Y

[@deepaktambe4167]

Please confirm that while testing soil sample for cbr, proving ring of 10 kN capacity is sufficient or not. In my opinion we require 50 kN capacity of proving ring.

[@HIGHWAYENGINEERING]

10 to 30 kn is sufficient...50 kn not give right result

[@pankajkumar-my6bq]

Sir kya river bed material can be used for granular sub base... can that material provided cbr value with in limits

[@HIGHWAYENGINEERING]

River Bed Material Only used if is Acceptable as per Specifications Mention Cleaarly...Some Where Only Crushed Aggregate allow...if RBM mix with Clay or Heavy Silt..its Cant be Used

[@errajeshbhawel8328]

Sir types B seal coat ki density? Ogpc density? BM density.....?

[@bhupendrasinghrajput9264]

dear brother, jo sample aap liye hai uski omc 13 % nahi aayegi. hamare idia se uski omc ,6. 7, ke karib honi chahiye. ,Ye omc soil ki ho sakti hai.but coarse aggregate ki nahi hogi.

[@HIGHWAYENGINEERING]

Yes. Sir... Definately aggregate omc should be 6-7%

[@Er.manishsingh]

Good morning sir 2.5mm or 5.0mm pe kiski value jada honi chahiye

[@motivationalquotes5105]

Genrally 2.5 mm ka Jayda hota hai. But if 5mm ka jyada hai to test repeat kro. If then also 5mm ka jyada AA Raha hai to 5mm ka corresponding CBR lelo

[@mecthologyesports]

What are the Maximum sizes of material for cbr? Couldn't hear clearly in the video

[@HIGHWAYENGINEERING]

19 mm sir.

[@mecthologyesports]

@@HIGHWAYENGINEERING u said something about 50mm sir. What was 50mm for?

[@manjudevi6491]

Sir when use 56 blows in CBR AND WHEN USED 10,30,65 BLOWS CBR TELL ME

[@HIGHWAYENGINEERING]

In ruaral road 56 blow test methode majorly adopted...but Highway or Airfiled roads work 10,30,65 blows test methode adopted...

[@nerdgamer4357]

is this same method of sampling for GSB CBR test

[@HIGHWAYENGINEERING]

Mould plus soil ko pani me kitna time rkhna hai

[@HIGHWAYENGINEERING]

96 hour

[@Azizkhanpk11]

Sir concrete ke sare test upload kro

[@shailjatamta5573]

And sir why we take the penetration value upto 12.5mm

[@HIGHWAYENGINEERING]

This is Standardized by irc

[@skbigproyt9603]

👍👍

[@shailjatamta5573]

Sir why we haven't do CBR test in case of wmm??

[@HIGHWAYENGINEERING]

Because wmm mix must be Aggregate type we also conduct AIV, Water absorbation, so CBR not needed... At the time of pavement design we assume it's cbr > 80%

Sir for proctor test ... Kon si seive use krege gsb k liye

[@mecthologyesports]

Hello sir. Is there a relation between the type of proctor test used(standard or modified) to find OMC and the type of compaction used in CBR(light or heavy)?

[@HIGHWAYENGINEERING]

Both compaction methods will be same for each test..its mean if proctore do by light ...cbr also do by light
