The geogrid is not less than 3 meters on each side, what does it mean?
I think it is not a few geogrid lap width than the roadbed width of three meters, and then backfill roadbed soil after 60 or 80 cm and then the two sides of the geogrid back.Or the design requirements are back folding 30CM
If each side is folded three meters, then it is folded. Design requirements are clearly not for this purpose,
At present, the largest width of single geogrid is 6 meters
