Sir , fantastic explanation. Such a critical step of Mix design - you have explained in such a simple way. 🙏

[@SatishIITR]

Thanks.

[@Rezzashah67]

Your this video made my sunday wonderful. Never seen analytical or rothfuch method ever before

[@SatishIITR]

Thanks Tanmay, You will certainly learn something new in every video. Please subscribe to the channel and send the link to your friends also. My next video is coming tomorrow (August 02) at 6.00 PM on Marshall Method of Mix Design.

[@bhupendra6372]

Another lecture where concepts are explained in the simplest yet elegant way. looking forward to future lectures.

[@SatishIITR]

Thanks Bhupendra for your comment. Please encourage others in your groups to subscribe the channel. We should take it to every student of Transportation Engineering. It can only be done through your help.

[@bhupendra6372]

@@SatishIITR Sure Sir. I am constantly forwarding the video links to the student groups that I know. I will further keep on doing that.

[@suryanarayanans4020]

Great to learn the Basic concepts of transportation engg from the legend researcher and Faculty whose research inspired me in my UG Highway engineering classes. Looking forward to more lecture videos. As a young researcher waiting to visit CRRI and learn more from you in person.

[@Arunkumar-cl7xs]

Dear Sir, Thank you for the video. As of now I have practiced for Trial and error method only. Hereafter I will change my approach with gradation of aggregate. which is most important part of the Mix designs as well as Job Mix formula

[@SatishIITR]

Thanks

[@be_independent1329]

Thank You Very Much Sir ❣️ It's Your Kindness to share these IIT Level knowledge with us, Otherwise most of the students have dreaming only to hear the Voice of IIT Professors to get some quality knowledge. You are doing great things for those students, who are not able to enter any IIT COLLEGE. 💜 Salute You Sir 💜

Thanks dear for your appreciation. This is the only objective of this channel to impart knowledge to all. Keep watching and share with others.

[@sokhengphai506]

Dear Sir, many thanks indeed for the video, this is excellence explanation. At the mean please advice, what is the desired grading for gravel surfacing, for base and sub base material.

[@SatishIITR]

desired grading for any layer is to be obtained from specifications. We follow MoRTH 2013 or MoRD 2014. All gradings are given in these books.

[@fabianwambanda8783]

[@ShriRamMarathe_PhD]

Respected sir,this was very informative. When I went to field, the field engineer was talking about one more grading called field mix formila. Can you explain more on "field mix formula" and how it is different from other gradation?

[@SatishIITR]

I have not head this terminology of Field Mix Formula and there is no such formula. MoRTH book provides some tolerance limits of gradation on each sieve size for Quality Control. But construction should be done with Job Mix Formula obtained in the laboratory only.

[@ShriRamMarathe_PhD]

@@SatishIITR Sorry sir I meant job mix formula only. Thanks for the corrections. However job mix formula is based on laboratory mix results only right sir ?

Sir, Please make video on "Polish Stoned Value" and its various application in safety point of view i mean,how we can modified surface properties near approaches near Junction

OK

[@JitendraKumar-lk1si]

Respected sir, thank you very very much. this was very Useful for me. Sir I have a doubt, how to draw grading of main line A,B,C. please resolve my problem if possible. thank you.

[@SatishIITR]

A, B, C are plotted in normal way on x-y axis. The balance lines are drawn in such a manner that the area on two sides is almost same.

[@sokhengphai506]

Dear Sir, I am struggle to understand grading, suppose if we have only one material at the site available, how do we deal with the situation. And the range and Mid Point value are given values as design values?

[@SatishIITR]

You cannot achieve desired grading with one type of aggregate

[@JASPREETSINGH-bj7sr]

A very good sir, Sir, I have four samples(A, B, C, and D) and I have also performed the gradation by following the morth table 500-17. Sir, I was following the trial and error method at 2.36 sieve samples C and D lies in the same range. I am confused about how to select the proportion with the same method.

[@SatishIITR]

If C and D lies in the same range, it may mean that only one of them is needed in the final mix. Try Analytical method. It is simpler and more accurate.

[@JASPREETSINGH-bj7sr]

@@SatishIITR Thank you so much sir.

[@amarpanchal5643]

SIr how to decide the proportions of materials to be mixed for marshall mix ?

[@SatishIITR]

Methods explained in this video are for proportioning of materials for Marshall mix also. Here also the materials available at site are of 20 mm, 10 mm , 6 mm and stone dust. You can porportion them by any of the three methods given in the video to get the final grading

[@mrVINODKUMAR12]

Dear sir, Thank you for your videos. I would like to ask you that how can we select critical sieves like 12.5, 2.36 and 0.075 etc for any mix design. Can you tell me for wearing course etc .

[@SatishIITR]

critical sieves are generally 2.36 mm and 0.075 mm for both wearing course as well as binder course. These are the sizes which make a mix either tender or stiff

[@mrVINODKUMAR12]

Thank you sir.

[@sundarsmart763]

Sir,sorry to interupt you again.In analytical method by using solver function It doen't show me the results after clicking the keep solver solutions.pls clarify my doubt sir It will be very helpful for me.

[@SatishIITR]

Do you get the solution if you do not click this button?

[@sundarsmart763]

@@SatishIITR No sir😣

[@vipinnegi3452]

Sir, how do we define the Range. Will it be as per MORTH or it can change according to the aggregate size

[@SatishIITR]

Range of gradation will depend upon the layer thickness and the type of mix. It is to be as per MORTH specifications.

[@thisisdpanchal]

sir in analytical method, my percentage of aggregate remains same, it is not working in excel...even though i followed same method as you described.

[@SatishIITR]

You must be missing something somewhere. Send your gradation table and target values to me through email. I will check.
