These highly-reflective, durable markers feature 3M™ Diamond Grade™ microprismatic optics and a ceramic lens coating to provide resistance to abrasion and cracking. Install them on concrete or asphalt with the supplied pressure-sensitive adhesive pad. Finger grips make handling easy and installation simple.
3M™ Raised Pavement Marker Series 290 (“Markers”) are designed for application on asphalt and Portland cement concrete road surfaces. The Markers have been designed to provide highly effective, long-term nighttime visibility in non-snow plow regions. Except for the color requirements for green lens, the Markers meet the requirements of ASTM D4280. The Marker bodies are made from an engineered thermoplastic that provides impact resistance and weatherability. The Markers include retroreflective elements that provide wet retroreflectance, dry retroreflectance, long-term nighttime visibility and are available in white, yellow, red, blue, or green. The Markers have been designed to be applied directly to pavement surfaces and are compatible with commercially available bitumen and epoxy adhesives. The use of any other type of adhesive should be thoroughly evaluated prior to any large-scale application. The Markers may also be fitted with pressure sensitive adhesive (PSA) pads. To use Markers with PSA pads, a liner is removed from the adhesive pad on the bottom of the Marker before it is placed onto the road surface.
