Sir please mention relationship between air voids and effective binder contain for asphalt mixes as we consider either Va=3.5% and corresponding Vbe=11.5% or Va=4.5% and corresponding Vbe=10.5% for design of flexible pavement using IRC-37:2018.
This relation is like this Va = VT - Vbe - Vagg Va = Air voids VT - total volume of compacted specimen Vbe - effective binder volume, and Vagg = bulk volume of aggregates
What should be done if achieved airvoid is more than designed airvoid after construction. For e.g if in design targetted airvoid considered os 3.5% and after construction field result shows 4% airvoids.
There is not much that can be done after the mat has cooled down to the cessation temperature. Therefore, air voids and density must be checked and achieved during rolling of the layer itself. However, layer will certainly receive some compaction due to traffic and this marginal difference of 0.5 % can be compensated by the moving load. But the large difference in design air voids and field air voids will create the situation of secondary compaction which will result in the surface rutting.
Sir actually I am having confusion of these topic but you have cleared my confusion with excellent explanation sir
I am happy to know it. Keep watching
Thank you sir for such a wonderful tutorial.
Thanks a lot. Keep watching.
Sir, This field density method taken from which code? Plz answer....
See ASTM D 1556
clear explanation sir. Thank you !
Thanks, please post the link on your LinkedIn page, if possible.
Sir ap Jo lecture dete same mere lab may hota Delhi Mumbai expressway
Then you can help me a lot. Send me small vidoes of actual tests, I will include them in my future videos.
Sir is it dynamic creep will be conducted at 6 percentage air voids?
generally at 4 % air voids
Sir please made a video on DBM design using RAP
I have already uploaded this video, Mix Design with RAP. Please watch and write your suggestion/comments

Vbe - effective binder volume, and Vagg = bulk volume of aggregates
Also sir pls mention the acceptance criteria for HMA specimen densification.... obtained as per both Gmb & Gmm... method..
It will change with type of layer and also type of road, hence avoided

Sir ap video bhut consept deta hi
Good or Bad?
Very very good sir 👌🙏
Sir please make a video on ogl sampling. (For both the case -i) existing road is to be widened ii) new alignment)
Ok, noted. Thanks
I could not find any details of OGL in MoRTH orange book. Can you tell me what do you need in OGL? frequency of tests on soil?
Sir Hindi my v
Yes, Jaldi hi koshish karunga. Thanks
