Can you please make a video on pavement design which has capping layer due to low CBR of subgrade with CTB base layer and CTSB subbase layer and specification of capping layer??

Concept of capping layer is no more in use now. IRC 37 suggests a minimum effective CBR of 5% for subgrade soil.
Plz Sir make video for Traffic survey and how to convert msa .

Dear Sir thank you very much for your nice video. I have read that wheels stresses diminish after 500 mm from the surface, is that correct

NO, wheel stress diminishes after 500 mm down the subgrade, not the pavement surface.

Thank for you video sir, can you pls explain meaning of semi infinite ..

infinite and semi-infinite are very relative terms. When we consider a layer which is finite in one direction and infinite in other direction, we call it semi-infinite. For example, a lyer of base course in a pavement is infinite in horizontal direction and finite in the vertical direction.
