Thank you for the informative session
Thanks Sam.
Best Explanation on Marshall mix design in entire youtube
Thanks Tanmay, Please forward the link to your friends also.
Very informative lecture sir.....easy to understand the concept of Marshall Mix Design through this video.
Thanks, keep watching and forward the link to others also.
Sir, you have explained the Marshall method of mixed design in a very systematic way.
Glad to hear that, keep watching.
Thank you sir for the wonderful presentation !
Most welcome!
Thanks a lot Prof. Satish Chandra Sir. It is very useful Lecture. I have shared in my Facebook page.
Thanks.
Have covered important concepts, there are very less videos which also discuss about the significance of obtained values and process which you have included very nicely. Thank you for the video.
Thanks. I am glad you liked it. Keep watching other videos also
Sir...Nicely explained with step by step procedure for mix design...
Thanks.
Respected Sir,
It is amazing lecture. It is definitely helps me a lot
Thanks, Watch other videos also. You will find them also very useful.
Thank you very much for the incredible lesson..
Thanks. Please share the link in your group for further dissemination
Really great session.
Thanks, keep watching.
It is very knowledgeable lecturer helpful for design the Bituminous Mix.
Thanks, Please share the link with your friends also.
Ok
Excellent Explanation By An Excellent Person 💯
I appreciate that!
Sir my all doubts are clear Thankyou ❤
Always welcome, keep watching.
Awesome video thank you sir❤
Most welcome. Keep watching.
thank you so much. i love your expression
Thanks a lot. Keep watching and share the link with others also.
I learnt a lot & remind me forgotten tes too.
Thanks. share with your friends also.
Very helpful and informative lecture
Sir Can you shere the ppt formate of this videos ?
Thanks, keep watching
good job
Thanks, keep watching
Nicely explained sir. One doubt step 4.2 GMM Maximum specific gravity of loose mix and GSB, Bulk specific gravity of aggregates are two different properties as per my understanding. Please elaborate on this point.
Yes, Gmm is the specific gravity for zero air voids, also called theoretical specific gravity
Gsb is the density of the compacted sample, it has some air voids also
Very informative video sir. Sir as you discussed here in the optimum binder content , check parameter is outside the range for redesign, how we check parameter, and where ranges will be find( in graphs?) ?
Ranges of all parameters (VMA, VFB, Flow) are gievn in MoRTH orange book for the diffreent types of mixes.
Sir, can we use 2% filler(cemwnt) in DBM mix (25mm Nominal mix) and what will be the benefits using the cement,
Hydrated Lime is better, because it provides anti-stripping properties to the mix. Cement will only add to Marshall stability and strength.
Thank you very much sir..
You are welcome. Keep watching and encourage your friends also to subscribe the channel. Also, see my latest video on IRC method of Flexible Pavement Design.
@@SatishIITR Ok sir..
Thank you sir
Welcome. I will be uploading its Hindi version on December 10. Watch that one also.
Thankyou sr
There are many more videos, you may like to watch on my channel
Cement concrete mix design (rigid pavements)
Yes, this topic is in my list. Thanks
thanks sir
Most welcome, keep watching
Sir, I have one doubt to be clarified. After preparation of mix and before compacting them in the mould, dont we need to place the mix for 2 hours of conditioning at compaction temperature? If we wont keep for 2hrs conditioning, doesnt it affect the binder absorption ?
Yes, we should keep it for conditioning. Thanks
Which specific gravity use of material to determine Gmm by equation? Apparent or bulk sir??
bulk specific gravity
Sir can we use Marshall mix design for other gradation also??
Yes, Marshall is used in almost all types of Bituminous Layers like BM, DBM, BC, SMA and others.
Sir Cracks is coming on my site just after laying and Rolling of DBM. Laying and Rolling temperature also maintained. what is the reason behind sir
Problem might be in the mix design. Issue of fines. May be due to excessive fines and low air voids.
Sir For BC grade 2,what percentages of bitumen content to be taken in order to find OBC.
The OBC for BC Grade is generally more than 5.0 percent. So start Marshall tests from 4.5 and go up to 6.5 percent in steps of 0.5%
Sir if we are using RAP or any waste material in Mix, then which method is recommended to find "Gmm".
equation method or Rice method
See my another video on Mix Design with RAP
@@SatishIITR Yes sir i watched...but in that video you said any one of these two method is used to find Gmm.. that's why i am asking sir..
which method will give precise value of Gmm.
@@thisisdpanchal Rice method gives correct value
Do we need test bitumen for specification before carrying out Marshall test
Yes, Testing of bitumen and aggregates are required to declare their suitabilty before going for Mix Design
@@SatishIITR thanks sir
Sir why we use Filler material in DBM or BC Mix Design
Filler material has many roles in a mix. It fills the voids in fine aggregates, after mixing with binder it creates bitumen - filler mastic which provides stiffness to the mix. It holds the binder and prevents bleeding in the mixture.
@@SatishIITR thank you Sir
provide Superpave Method of Bituminous Mix Design
Ok, will do soon
For 1 marshall sample preparation approx 1200gm of material (aggregate + filler) is required. How is bitumen quantity measured and mix in percentage for 1200gm?
binder is taken by weight of total mix. If binder content is 5%, take 60 g bitumen and 1140 g aggregates.
@@SatishIITR thanks sir🙏
@@saurabhanand1807 you are welcome.
Sir, is there any code book for Modified Marshall test?
sent the file to your email address. ASTM D 5581 explains the procedure
@@SatishIITR , Thank you so much sir 🙏
Hello sir,
Which method will be best for obtaining OBC ? NAPA or Asphalt Institute Method?
Both are equally good.The Indian Specifications suggest MS-2 method
@@SatishIITR Thank you Sir.
@@SatishIITR Sir I have seen the 7th Edition of MS-2. But I could not find the method of calculating OBC as you said in the video. The 7th Edition of MS-2 stated similar statement like NAPA.
@@rajamistry1008 Yes, MS2, 7th edition suggest OBC corresponding to the design air voids and then checking the other marshall parameters.
Sir I have a question that , %Vv+%Vb+%Vaggregats=100 ?
Yes, it should be
@@SatishIITR But In laboratory it's not happen , 1 /2 %variation !! Whai is reason for it sir??
@@jawanvai8782 cannot say, may be number of digits after decimal playing some role.
Sir where mentioned 63.5+- 3 mm
In both MS 2 and ASTM
@@SatishIITR in MS-2 CHAPTER -7 ,page no -80 , 63.5+-1.27 likha hai
@@Blogcompany_New will check again.
@@SatishIITR please send your WhatsApp nmbr I will send
Binder content shall be selected to obtain .......% Air voids
(1) As per IRC 37 2018- 3.5% (Page 31)
(2) As per MORTH 5th Rev Clause 505.3.2 - 4% ( Page 178)
(3) As per MS 2 7th Edition Clause 7.4.4 - 4% ( Page No. 85)
Which .....% is to be taken from above for DBM Mix Design?
How to compare volume of bitumen in DBM Mix Design?
Please suggest
Take as per IRC 37, 2018.
Thank sir
Can you see Me
??
Sir, am not understand in English please understand in KANNADA /HINDI
OK. I am uploading its Hindi version today at 4.00 PM. Watch it and then write your comments
