This study investigated the feasibility of using fiberglass reinforced plastic material as an alternative to aluminum for highway sign panels. An analysis of shop fabrication, installation procedures, field performance, reclamation, and cost was made for each material. It was concluded that the fiberglass reinforced-plastic material is an acceptable alternative to aluminum, and the Department should consider its use for highway sign panels on which to attach the reflectorized sheeting.
