Metal Concentrations for Arsenic, Lead and Antimony for Glass Beads

Citing the findings from research sponsored by the New Jersey Department of Transportation and the American Glass Bead Manufacturers’ Association, the Fair Glass Bead Market Access Coalition renewed its support for regulatory efforts to determine appropriate heavy metal concentrations for arsenic, lead and antimony for glass beads used in pavement marking applications.

The American Association of State Highway and Transportation Officials (AASHTO) empaneled a task force in 2007 Chaired by New Jersey DOT Bureau of Materials Chief, Eileen Sheehy, to review the metals in glass issue. The just released New Jersey DOT sponsored research by Rowan University and the New Jersey Institute of Technology is a key step in that process. Dr. Adi Raut Desai, of the Texas Transportation Institute, presented his industry funded metals in glass research, at the 41st Annual meeting and Traffic Expo of the American Traffic Safety Services Association. Using glass beads provided by the American Glass Bead Manufacturer’s Association, Dr. Desai reported that he was able to create an environment in which the glass beads leached metals.
