RE: [greenyes] Specs for plastic lumber for highway posts
Hi John -

I did some research on this for EPA sometime ago which is this link:

http://www.epa.gov/cpg/products/signage.htm

But it looks like this APC site could be a good references...

http://www.plasticsresource.com/s_plasticsresource/rpd_default.asp?trackid=&;
cid=86&did=539

and here's a manufacturer...

Good luck!

Subject: [greenyes] Specs for plastic lumber for highway posts


Does anyone know of test data for plastic lumber for use as highway sign or
crash barrier posts?

My Highway Commissioner said that the ACQ treated posts that they are using
for signs are not working, as the aluminum signs and metal bolts are rapidly
corroding -- to the point of the signs falling off the posts after six
months.

The Highway Department would like to try plastic lumber posts, but need test
data -- especially "break away ability'' -- to show that they are suitable.

Thanks much,
