Manager [mailto:becky@lancasternh.org] My understanding is that NH DOT approves
the use of crushed glass in its public works projects but only to a point of
10% of total aggregate volume. Not sure where one would confirm or refute
this. Becky Newton Administrative Services Manager 788-3391 From:
owner-PW.Net@lists.unh.edu [mailto:owner-PW.Net@lists.unh.edu] On Behalf Of Bruce Berry Jim, While Director in Rindge, I used it a lot.
We had a crusher fed directly from a live floor bin, made about 30-40 yards of
crush glass yearly and used it in both culvert bedding and underdrain. I found
the results very positive, I called it cost avoidance, replacing the need to
purchase (in applications with water present) ¾-11/2 “washed” stone
with crushed glass. Glass will compact consistently too 95%. I also used it
behind a concrete block retaining wall with 6” perforated pipe with very
good success. I never had a frost issue. Rindge has since abandoned the
practice. Kind of took the curse off of paying to
get rid of glass and paying to purchase stone. As soon as I get a crusher purchased, and
in place, I plan to restart the practice here in Bruce W. Berry, Director Amherst Department of Public Works Phone 673-2317 ext 204 Fax 249-8857 From:
owner-PW.Net@lists.unh.edu [mailto:owner-PW.Net@lists.unh.edu] On Behalf Of james terrell Has anyone tried crushed glass ( PGA) as bedding for culverts.
If so what were the results? How did it affect frost heaving in the areas where
it was used?
Thanks, Jim Terrell Town
