Dear sir, If my axle configuration is 1.221, 1.121, 1.122 will it be considered as tridem axle or tandem axle during axle load spectrum frequency analysis. Also some time Axle with configuration of 1.222 one of the middle rear tridem axle is lifted up then will it be considered as tridem axle or tridem axle??
It is obtained from axle load survey data. For example, let us say the total number of axle repetition of tandem axle for top down cracking is 2743873 Axle load data shows that 14.5 % of total tandem axle in the axle load class of 380 - 400 kN is 14.5 percent. So expected repetition for this load class will be 14.5 percent of 2743873 = 397,861. Hope it is clear now.
That is a totally different concept. See my video of white toping ruclips.net/video/d_8lJB-Kfm8/видео.html Rigid pavement slab requires a uniform and firm support and damaged pavement cannot provide the same.
@@SatishIITR sir, if the damaged flexible pavement has black top finished..den after levelling the crust with gsb and then doing dlc and den PQC...will it not work this way??
The average number of axles per CV will depend on the traffic composition. I mean the propostions of trucks with 2 axles, 3 axle, 4 axles and so on. Higher is the number (or proportion) of the trucks with more number of axles (3 axles and more) greater will be this value. It is not fixed rather it is to be calculated from axle survey data.
Thank you, sir, for this video, I am pointing out one error in the example of computation of two-way commercial vehicles during the design period , the expression shown by guideline and your video both miss the (-1) in the numerator. Please sir check it and clarify. and sir Please upload the excel sheet and link for us. Again thank you for putting a lot of effort into us.
Yes, you are correct. I checked it agian, there should have been (-1) in the numerator. But the calculation is made with (-1) only and therefore, the value of C is correct. Thanks for pointing it out.
Sir very nice explanation can you please provide the slides and Excel sheet it will be helpful for my presentation life me first time itna aacha se degign samjaya h koi ❤

Sir can you make a video on how to perform tests on pavement for its quality check....so that a common citizen of our country can understand in a better way....
A common man will only be able to assess the physical condition of the road that is visible to the eyes. I uploaded one video on determination of field density and air voids in bituminous layers. Will try for other layers also.
Evaluation of Flexible Pavement by FWD is already uploaded. Watch it here: ruclips.net/video/yMdp9H57FWo/видео.html I have not made video on IRC 117. will do soon.
It is the total number of axles divided by the total number of CV. For example there are 100 commercial vehiclea and out of it 60 are two axle trucks, 30 are 3-axle trucks and 10 are 5-axle trucks. Now total number of axles are 60x2 + 30 x 3 + 10x5 = 260 axles. The average number of axles is 260/100 = 2.60 Hope it is clear now.
Respected sir, can you please make video on SFRC Pavement as per SP 46:2013? In SFRC Pavement, are the curves required to find flexural stress different or is it as per IRC58:2015?
Hahaha, Writing a book is not an easy task, my dear. It requires lot of time and effort. I have so far written 3 books and two manuals (latest is on Testing of Highway Materials, coming out soon). Thanks
@@SatishIITR sir ,may I get that PPT & Excel sheet of your lecture design of rigid pavement for low volume traffic,IRC SP 62...it will be very helpful for me.. thanking you
Thanks you very much sir...sir i am calculating stress in pavement with the help of FEM tool as a M.tech dissertation.Can you suggest something to be included in my work or can you please drop you mail-id.
First of All, Thank you sir...!!! Sir, pls keep making PDA videos in hindi, thank you so much for Videos, from bottom of my heart
Thanks Akshay, Another video in Hindi uploaded yesterday on Design of Flexible pavements for low volume roads. Watch and write your comments.
Thank you so very much sir. This video has helped me a lot
Really happy to learn that it was helpful. Keep watching. There is English version also of this video.
Dear sir,
If my axle configuration is 1.221, 1.121, 1.122 will it be considered as tridem axle or tandem axle during axle load spectrum frequency analysis. Also some time Axle with configuration of 1.222 one of the middle rear tridem axle is lifted up then will it be considered as tridem axle or tridem axle??
only the last one 1.222 is the tridem axle here. Consider it tridem only even if one axle is raised, it is temporary.
Sir if I have the Calculated MSA, CBR and width of Road available, then the design of Rigid Pavement is Possible by any method?
Not by IRC 58. You need an axle load spectrum.
If it is not available, assume some based on past data
Sir Any design of reinforce siol Retaining Wall
No, I have not uploaded any videos on this topic

Very nice good explanation
Thanks Akash. Share the link with your friends also
Thank you Sir
Most welcome. Keep watching
sir how we can determine the expected rep (ni)
It is obtained from axle load survey data. For example, let us say the total number of axle repetition of tandem axle for top down cracking is 2743873
Axle load data shows that 14.5 % of total tandem axle in the axle load class of 380 - 400 kN is 14.5 percent. So expected repetition for this load class will be 14.5 percent of 2743873 = 397,861.
Hope it is clear now.
If we have to design rigid pavement over damaged flexible pavement surface do we have to take DLC below PQC
That is a totally different concept. See my video of white toping ruclips.net/video/d_8lJB-Kfm8/видео.html
Rigid pavement slab requires a uniform and firm support and damaged pavement cannot provide the same.
@@SatishIITR sir, if the damaged flexible pavement has black top finished..den after levelling the crust with gsb and then doing dlc and den PQC...will it not work this way??
Sir ,what do u mean commercial vehicle, explain
Any vehicle with laden weight of 3 ton or more. The definition is given in IRC 37 also
Ok sir
Good evening 'useful U tube.please give a knowledge of Roughness Index of Rigid pavement.
Will try, thanks for watching
Sir,What should be the temperature differential value for tripura/mijoram?
For all hilly regions the values of Temperature Differential are to be taken from the first row of table 1 of the IRC 58.

Sir what do we do for Greenfield Alignment? How to decide pqc thickness.
Design procedure remains the same. The axle load data will be taken on a similar type of highway.

Sir
Good afternoon
It is told in IRC 58 2015 that the average number of axle per 2.36. But the one I sent you has 2.65. why is it so
The average number of axles per CV will depend on the traffic composition. I mean the propostions of trucks with 2 axles, 3 axle, 4 axles and so on. Higher is the number (or proportion) of the trucks with more number of axles (3 axles and more) greater will be this value. It is not fixed rather it is to be calculated from axle survey data.

Thanks sir 🙏super
So nice of you
Sir,
Good Morning
I didn't understand. Please tell me through example
It is the total number of axles divided by the total number of CV. For example there are 100 commercial vehiclea and out of it 60 are two axle trucks, 30 are 3-axle trucks and 10 are 5-axle trucks. Now total number of axles are 60x2 + 30 x 3 + 10x5 = 260 axles. The average number of axles is 260/100 = 2.60
Hope it is clear now.
Thank you sir.If you have time you can talk about refusal density
OK, noted
