The objective of this study was to evaluate available snowplowable markers under similar traffic and snowplowing operations. There were five different markers tested which included the following: 1) Stimsonite 96, 2) Dura-Brite, 3) recessed, 4) Kingray, and 5) Prismo Roadstud.

The Stimsonite 96, Dura-Brite, and recessed markers were found to be acceptable snowplowable markers. All three of these markers were found to have adequate reflectivity during both dry and wet nighttime conditions. This reflectivity was maintained over the test period and the markers proved to be durable when subjected to snowplow operations. However, considering all available input, the recessed marker is recommended as the most functional and cost-effective.
