Abstract

A newly developed non-skid surface treatment has been applied to the concrete apron and toll booth area at the milford toll station on the connecticut wilbur cross parkway. This coating, approximately 1/4 in. In thickness, consists essentially of sharp, hard aggregate, approximately 35 mesh, permanently bound to the concrete deck with a thermosetting epoxy resin. Heavy traffic volume through the milford toll booth, along with the degrading action of de-icing chemicals, had caused an excessive amount of concrete spalling and wear. This resulted in a dangerously slippery area where automobiles must continuously stop and start. The material was applied to this area to prevent skidding, smooth out the rough and spalled areas, and protect the concrete apron from further degradation. A small crew of men made the application with equipment and materials which are presently commercially available. Although some initial difficulties were encountered, approximatley 12,000 sq ft, including toll booths and a downhill approach, were successfully coated in a relatively short time. The good safety record at the milford toll booth since the application two years ago testified to the effectiveness of the coating as a skid-proofing material. Frequent physical testing of the coating has indicated little degradation of the coating itself or of its adhesion to the concrete deck since it was applied.
