Thanks all for the info on the PSP. We are actually looking to buy some if
the $$$$ is right for northern Canada operations where concrete is too
expensive and gravel and fine sand are cheap.

I would seriously look at geotextiles first. You can go with either a
geotextile mat under a gravel surface course, or the use of a
geotextile grid with sand/gravel fill. Both are easier to install,
require less transport costs, and easy to repair (when you try
replacing a few PSP panels in the middle of the mat, you will
understand what I mean g). They offer tremendous load carrying
capacity in comparison to their weight and construction effort, and
take better advantage of those "cheap" resources you mention. I
designed a stretch of roadway which used the geotex mat, and it was
installed by troops who had never before seen the stuff with little
difficulty. And the geotextiles are not that expensive
either--probably cheaper than buying a bunch of PSP and lugging it all
the way into northern Canada!

I am looking for some info on PSP (perforated Steel Plates - that

used for temporary runways, aprons and parking areas. Also looking for a
source of approx 100,000 sq feet of the stuff if any is still around in
useable condition. Any pictures or data would be appreciated
