Identifying wet pavement subgrades through nondestructive techniques

Identifying wet pavement subgrades through nondestructive techniques

Identifying wet pavement subgrades through nondestructive techniques

(OP)
Does anybody know the best method for identifying wet soils beneath existing pavements? I have heard of using GPR, but does it work well where clays are present. Also, what about infrared imaging. Is this possible?

RE: Identifying wet pavement subgrades through nondestructive techniques

I don't know about non-destructive, but it wouldn't take 'much' destruction to get a core sample, and check the moisture content.  You could do it with a masonry bit to get through the pavement, and then a wood auger bit to bring tailings to the surface.  It wouldn't take more than a 1" hole, and you could use a hand drill (but probably not cordless.)

RE: Identifying wet pavement subgrades through nondestructive techniques

GPR does not work well for that.  Infrared thermography will work on relatively thin pavements.
