Design of Flexible Pavements for low volume roads, IRC:SP:72-2015, Pavement thickness & composition

[@betu2010kiit]

Well explained Sir and one of the first videos on low volume roads in KZbin platform.

[@SatishIITR]

Thanks. Pease ask your students also to watch it once.

[@venkateswararaothumati6734]

Good afternoon, sir, can you please suggest minimum ucs value of stabilized subgrade of expansive clay for low volume roads

[@SatishIITR]

This code does not specify any UCS value of stablized soil. But IRC SP 89 Part II suggests that the UCS for stabilised subgrade should be as given in the latest IRC 37. Check it there.

[@ahmedsharul6747]

Crystal clear concept, Sir kindly make a video on DCP test.

[@SatishIITR]

Thanks, suggestion noted.

[@SatishIITR]

OK

[@Harish-Adil]

Excellent

[@SatishIITR]

Thanks. Share with your friends also, please.

Thankyou sir for the videos and i have a doubt i.e." Why we use Lane distribution factor in MSA ? What is the purpose of using it in CSA formula ? I hope you will reply sir .

[@SatishIITR]

Lane distribution factor is used to account for the directional split in the traffic. On a two-lane roads, for example, if total traffic is 1000 veh/day, it is not fair to assume that all the vehicles will follow the same path as half of them will only be moving in one direction. Therefore pavement should be designed for the traffic less than 1000 vpd. For this reason, lane distribution factor of 0.75 is considered for two-lane roads. For a single lane road, there is not much width to distribute the traffic laterally in two directions, therefore this factor is 1.0. I hope it answers your query.

[@bhushanchauhan7011]

Agar CBR 6 to 7 ho to aur traffic Catageory T5 To kon sa pavement design consider kare?

[@SatishIITR]

Flexible will be better

[@bhushanchauhan7011]

OK, CBR range 6 to 7 ko S3 Ya S4 me se kon sa column k hisab se design karu? Kynki CBR range 6 to 7 k liye Mujhe koi exact column nahi dekha Pavement design catalogue me.

[@SatishIITR]

@@bhushanchauhan7011 Use templet correcsponding to CBR 5 - 6 %. CBR me 1 % change se kuchh fark nahi padta design me

[@Dani_4_Christ]

Very nice video sir. It seems only single and tandem axles considered for design. Why Tridem axles are neglected sir ??

[@SatishIITR]

There are no tridem axle vehicles on Rural Roads. If they are, then almost negligible.

Hello sir, I'm having a lot of doubts regarding the project.. how can I contact you?

At 9.41 Recommended VDF, Calculations for MCV 0.34 & 0.02 not furnished . 🙏

[@SatishIITR]

basic equation is same, fourth power law. Try yourself.

[@Dani_4_Christ]

Sir, can you give references for presumptive CBR values based on soil characteristics.

[@SatishIITR]

It is taken from Unsealed Roads Manual, ARRB 1993

Sir can i get ur num this is the project we are working on can i speak to u sir
