Hi Berhanu, good to see your comment. I launched this channel in June 2021 to address some typical topics in Traffic and Highway Engineering. How are you doing, send an email giving some details of your work after you left Roorkee.

Thank you so much sir for videos, currently we are performing this test following ASTM D 7693 by UTM- DTS 30. We are getting values around 4000 to 5000 as an average of all pulses for VG 30 BC gradation.

[@SatishIITR]

A value of 4000 - 5000 with VG 30 is a bit higher.

As per en 12697-26 how much peak load is required for resilient modulus?? Sir because in astm d 4123 clearly stated that 10 to 50% of ITS is required for Mr.

[@SatishIITR]

I do not have this code with me at present. We are generally following ASTM code

[@vatsalbu8989]

Is Precondition required when testing the CORE Samples?

[@SatishIITR]

Yes.

Dear Sir, Please make a video on semi-circular bending test.

[@SatishIITR]

OK, but it will be very specific to research students only. Not for general viewers.

[@diyasudheer616]

Sir,what is the name of this apparatus used

[@SatishIITR]

It is a normal UTM. But you need a zig for Resilient Moulus to conduct this test.

[@civilthings6749]

Sir, is the resilient modulus and dynamic elastic modulus same?

[@SatishIITR]

Yes. For Asphalt mixture they are almost (not exactly) same.

Sir i am not able to understand how the data extraction is happening and how the calculation is being done...

[@SatishIITR]

But there is no data extraction or calculations in this video. Where is the confusion?

[@Ab00783]

no sir i m not asking about the video. but when i try to put the data on offline filter software there were various graphs which were extracted from raw data..from those graphs certain values are to be taken. i was not able to understand how that offline filter works. @@SatishIITR

[@shijithnatpac]

Dear Sir, First, thank you for your valuable time and effort in making such an excellent video. I doubt how the FWD back calculated elastic modulus values related to the laboratory-tested value. Will these values be the same or vary. I have FWD back calculated value for a particular homogeneous section. to know the laboratory value, I have collected core samples also. But I was unable to perform this test due to unavailability of equipment. can I use any co-relation to find MR value through any laboratorian test?

[@SatishIITR]

If you are talking of bituminous layers, there is a correlation between Mr and ITS as given in IRC 37, 2018. But this relation is very vague and does not give correct value. In the case of granular materials, determination of Mr. in laboratory is a tedious method and therefore, better to believe your back calculated values only. refer this paper also onlinepubs.trb.org/Onlinepubs/trr/1985/1022/1022-007.pdf

Sir, can we find resilient modulus for microsurfacing mix?

[@SatishIITR]

Microsurfacing is not a structural layer. It is laid in a thickness of 8-10 mm to improve the riding when the road is otherwise sturcturally sound. So there is no need to determine Resilient Modulus of this layer. It is not considered in the design.

@4:03 the definition of resilient modulus is wrong

[@SatishIITR]

Yes, it is the ratio of stress and strain and not of the strain and stress. Thanks
