How to estimate Effective CBR of subgrade soil? When Embankment is in multiple layers.

This video explains the procedure of estimation of Effective CBR for the design of flexible pavements as per IRC 37, 2018.

Clear sir... Thanks for your sessions I am regularly watching your previous sessions.

[@SatishIITR]

Always welcome, keep watching

[@ramawadheshkumar5313]

excellant explain about effective cbr

[@SatishIITR]

Glad you liked it. Keep watching

Thanks sir for explan CBR of subgrade soil.🙏

[@SatishIITR]

So nice of you

Thanks, You can skip the ad part.

[@milindjamble7987]

Nice explanation Sir And congratulation on receiving award

[@SatishIITR]

Thanks a lot, Milind Ji.

[@prpt2407]

We also know about the Award..and congratulations to sir

[@SatishIITR]

@@prpt2407 Thank you so much. It is with blessings of all well wishers like you.

[@rameshdhimal3428]

Can you please make a video on pavement design which has capping layer due to low CBR of subgrade with CTB base layer and CTSB subbase layer and specification of capping layer??

[@SatishIITR]

Concept of capping layer is no more in use now. IRC 37 suggests a minimum effective CBR of 5% for subgrade soil.

[@ErCSPatel-zx6mi]

Plz Sir make video for Traffic survey and how to convert msa .

[@SatishIITR]

OK.

[@aalex5842]

Dear Sir thank you very much for your nice video. I have read that wheels stresses diminish after 500 mm from the surface, is that correct

[@SatishIITR]

NO, wheel stress diminishes after 500 mm down the subgrade, not the pavement surface.

[@gvarun2192]

Thank for you video sir, can you pls explain meaning of semi infinite ..

[@SatishIITR]

infinite and semi-infinite are very relative terms. When we consider a layer which is finite in one direction and infinite in other direction, we call it semi-infinite. For example, a lyer of base course in a pavement is infinite in horizontal direction and finite in the vertical direction.

[@gvarun2192]

Sir, If there is a filling of more than 2 Mtr, How much depth of Embankment will be considered for Design purposes for calculating effective CBR.

[@SatishIITR]

@@gvarun2192 Embankment depth below subgrade is taken infinite.

[@gvarun2192]

​ Thank you very much for your reply sir.

Is there any video of IRC 15, 2017?

[@SatishIITR]

I have uploaded one video on concrete mix design. watch it here kzbin.info/www/bejne/jHPVgZKsopeMqaM
