Geotextile fabric placed over stone?
(OP)
Got a quick question from a client of ours. They're placing precast box culverts and the DOT inspector is stating that the geotextile fabric used for subgrade improvement should be placed above the crushed stone subgrade. I've never heard of anyone doing this but apparently they insist this is how they've always done it. I informed our client this but wanted to see if anyone else had ever heard of people placing geotextile above crushed stone.
Also, this isn't wrapped around the stone for confinement and it's not for slope stability. Strictly for subgrade improvement.

a) placed compacted road base with no geotextile
b) poured a concrete working slab with no geotextile
option b provides the best working surface for placing and sliding the box sections into position. much harder to do on a gravel surface.
