RAISED-AGGREGATE, LANE-DELINEATION STRIPE
Experimental raised-aggregate (1/2 inch (13 mm) to 1 inch (25 mm)) traffic stripes were installed on approximately 0.4 mile (644 m) of US 60 just north of the intersection with US 421 in Franklin County. Installation was during June 1974. Aggregate stripes were painted yellow and used as skip lines inside the continuous channelization stripes to indicate no crossing into the two-way, left-turn lane except for turning movements. Observations indicated that the raised-aggregate stripes had good durability after being exposed to 2 years of wear. During dry, nighttime conditions, the paint stripes were slightly more effective than the aggregate stripes; but raised, pavement markers simulating a paint stripe were superior to either method of delineation. Aggregate stripes provided a substantial improvement over paint stripes during wet, nighttime conditions; but raised, pavement markers were most effective. The aggregate stripes produced an increase of approximately 3 dBA in the noise level compared to an increase of 5 dBA when driving over raised, pavement markers arranged to simulate paint stripes. Raised-aggregate stripes were uneconomical when compared to regular paint stripes, thermoplastic striping, and raised, pavement markers. The cost of aggregate stripes would most likely decrease if installation were on a larger scale.
