@@HIGHWAYGUIDE in CTB flexural strength (modulus of rupture) is taken @ 20% of unconfined compressive strength (UCS) value. Max limit is 1.40 MPa for cement- aggregate CTB.
@@imses3660 OK, with reference to IRC SP 89(Part ii) 2018, CTB flexural strength (modulus of rupture) can be taken @ 20% of unconfined compressive strength (UCS) value. The default value can be taken 1.40 MPa for cement- aggregate CTB means 7/28 days compressive strength required 4.5/7 MPa ; so in the absence of any data you can keep 4.5 Mpa (7days) minimum compressive strength for CTB mix design. Actually designer will tell you this data based on fatigue analysis using IIT pave software. Base on that data you have to convert it into UCS. Casting of beam is not necessary in laboratory, it is not mandatory. If you have sufficient manpower & sufficient time you can do on your own.
There is no individual test for plasticity index , find out the Liquid Limit & Plastic Limit as per standard procedure , procedure is available in my channel. Plastic Index = Liquid Limit - Plastic Limit.
Compaction method for ctb
Sand Replacement
Please sir make the FULL video of full experiment of CTB/CTSB
Sir, physical requirements for ctsb material and test required???
Will post a video soon.
As usual informative video thank you sr
Keep watching
Sir ji CTB ki full kya h ji
CEMENT TREATED BASE
Sir Gsb or wmm me FDD test krte hai or DLC me bhi to CTB me konse test krege for compaction ?
Sand Replacement
Any were mention about minimum laying thickness for CTB. ??
Thickness is based on crust design.
@@HIGHWAYGUIDEfine, crust design is there, but minimum laying thickness?
As per IRC 37 - 2018 , recommend minimum thickness for CTSB layer is 200 mm.
@@roshangawarle9019 Already told CTB thickness is based on design.It may be from 100 mm to 170 mm. No minimum criteria
Any design soft copy sir
150x150mm Cube casting process, means kitna layer, vibration/compaction procedure etc. mould casting any video
Modified Proctor density test kiya, mdd-2. 43,omc-8.1
Ucs test time loading rate?
Can you tell me the compaction method for cube
Thnku Sir 🥰🥰🥰🥰
I was waiting for this for a long time
Thank you sir
So nice of you
CTB @4 percent cement what is the lab test available pl suggest
Unable to understand your question
Sir pls make video on aggregate relief layer. Design.
Aggregate relief layer is nothing but it is simply WMM layer.
Thx once again sir,
Keep watching

When design is based on compressive strength no need of talking about casting of beam for flexural strength.

Ty sir
Sir please make one video on Mastic Asphalt Mix Design
OK will try
Sir kab std &kab modified proctor karenge iska criteria bato please
No criteria , you can use on your own.
Please sir technical specification of ctrb next video
No Idea
Sir , please upload video of WMM Plasticity index test.
There is no individual test for plasticity index , find out the Liquid Limit & Plastic Limit as per standard procedure , procedure is available in my channel.
Plastic Index = Liquid Limit - Plastic Limit.
Sir step2 isko thoda or clear kijye sir..
Ok next time
Dear sir please make a video about how to check cement content in CTB
Ok will try
Sir excel me CTB KI DESIGN MIL SKTI HAI , dheeraj88585@gmail.com
