Subject: Re: Use of glass cullet as a pipe bedding material (Baard Arntsen)

May 14, 1997

Dear Baard Arntsen,

I have heard of some projects that have used glass cullet in construction materials, road-building, and similar uses. You are seeking research studies. Here are specific ones of recent vintage that are in the Research Library:

 Using Recycled Glass as Construction Aggregate: A Summary of the Glass Feedstock Evaluation Project by the Clean Washington Center. The summary and the full report are available from the Center at their website:

Also from the Clean Washington Center are other reports with possible applicability emanating from their Glass Markets Information System .

Another research study is: Reuse/Recycling of Glass Cullet for Non-Container Uses by the Dane County Dept. of Public Works, Madison, WI. Contact person was John Reindl. Address: 115 W. Doty St., Rm 2144, Madison, CI 53703

Another: Glass Feedstock Study by Dames Moore, Engineers, July, 1993 should be available from them or from the State of Washington Dept. of Transportation.

A last thought is that several US states departments of transportation have conducted studies of using substances like tire rubber and incinerator ash for the purpose that you propose to use cullet. Perhaps they studied cullet, too?

Here are several contacts on that thought:

Maine State Dept. of Transportation and also Dana Humphrey, Dept. of Civil Engineering, University of Maine, Orono.

New York State Dept. of Transportation (has sponsored glassphalt projects)

Minnesota Pollution Control Agency, Waste Tire Mgmt. Unit, 520 Lafayette Rd., St. Paul, MN 55155

There is also an older document from the OECD Road Research: Use of waste materials and byproducts in road construction publiced by the OECD in 1977.

Hope that this helps.
