Nice Explanation sir.. Tqqq so much........

Welcome

Acceptance Criteria for compressive strength of Cube pe v 1k video digiyega Sir

[@SatishIITR]

thoda detail me bataynge aap kis video ke liye kah rahe hai.

[@rohitvasudeva9199]

Sir Please make a demonstrative video similar to this video for plate load test.

@@SatishIITR Thank you very much Sir Thanks for guidance Sir

[@krishnamoybhattacharyya2194]

Sir, please make a video regarding Pile Load Test

[@SatishIITR]

No Dear, that is not my area. It is Geotechnical Engineering

[@krishnamoybhattacharyya2194]

@SatishIITR Ok sir

[@vamsidharreddy9828]

Hello sir, can we test cbr specimen in marshall stability machine

[@SatishIITR]

No, the rate of loading in Marshall machine is different. For CBR, you need penetration @ 1.25 mm per minute and this is not possible in the Marshall machine

[@luvtunes]

Sir, is the compaction in mould should be in 5 layers with 55 blows of hammer for both heavy and light compaction of soil?

[@SatishIITR]

Yes. Hammer will be different

[@vivekkandpal7074]

Sir how we rate the significant amount retain on 19 mm sieve...i mean how much minimum amount of soil we should replace in the size of soil partical bigger then 19mm...and sir please make a video on effective cbr

[@SatishIITR]

Any amount above 19 mm must be replaced by the fraction passing 19 mm and retained on 4.75 mm. There is no guidance on what is the significant amount. So better to replace even if it is small proportion. I have already uploaded video on effective CBR. See the playlist once

[@peoplespowerhellyeah8619]

Sir,how do we find what amount of compaction energy require to achieve 97% of MDD? Final compacted depth at 97%of MDD...HOW TO FIND WHAT AMOUNT OF COMPACTION IS REQUIRED.

[@SatishIITR]

That you will have to do by trial and error method. Make a curve between number of blows and MDD and then choose the number of blows.

[@sundarsmart763]

Sir,gud mrng I have one doubt why cbr at 2.5mm penetration is higher than 5mm.And also IS 2720 suggest that surcharge load should be equal to weight of pavement.how can we provide that much surcharge weight sir.kindly clarify my doubts sir

[@SatishIITR]

CBR at 2.5 mm should ideally be higher as here we are measuring the resistance at lower penetration. The initially, resistance offered by the soil is more. Yes, it is not possible to estimate he correct surcharge and therefore a normal surcharge of 2.5 kg is good enough.

@SatishIITR thnk u soo much sir.....🙏🙏🙏

[@ravitejamurala9854]

Hello sir , how do we consider the OMC % at 97% Compaction (97% of MDD) for CBR Mould Casting and if we consider the OMC from Graph at 97% MDD , we will get two OMC , one is at dry of Optimum side and another at wet of Optimum side , which OMC we have to consider for CBR Mould casting process for 97% Compaction ????

[@krishnamoybhattacharyya2194]

Sir, how to calculate effective CBR value?

[@SatishIITR]

OMC is taken on dry side of the curve (never on wet side).
