Tine finishing of plastic concrete is gaining acceptance throught the U.S. in helping to prevent wet skidding accidents. This finish involves the use of pieces of metal or tines, which are fixed to a board on a set spacing. This board is dragged across the pavement either mechanically or by hand, causing the tines to form grooves in the pavement. Tine finishing studies have employed 2 different spacings, approximately 1/4 inch by 1/2 inch spacings. The finish that had the best drainage characteristic was that with the 1/2 inch spacing. Arkansas efforts are described where special provisions required the tines to be approximately 0.32 by 0.83 inch steel flat wire, 4 inches to 5 inches in length, spaced on 1/2 inch centers. The groove produced in the concrete was from 1/8 inches to 3/16 inches in depth.
