Specifications include, but are not limited to: (1) Tubular Delineator Posts and Guardrail Markers shall consist of a flexible, durable, and non-discoloring material that is 2 to 4 inches in diameter and resistant to ultraviolet and infrared radiation. Tubular delineator posts and guardrail markers shall be permanently closed or capped to prevent moisture or debris from entering. The upper end of the post/marker shall be flattened to provide an area at least 3 inches wide and 12 inches long to accommodate retroreflective sheeting. Posts/markers shall be white, yellow, or light gray in color. Once installed, the delineator posts and guardrail markers shall be resistant to overturning, twisting, leaning or displacement. The posts must be compatible with an anchor that holds the post in place by a locking mechanism or bolting arrangement that provides a simple method of attaching the original post, or subsequent replacement posts, to the anchor with few to no tools. Simplicity, safety and function of this postto-anchor connection will be a consideration in the award. (2) Extrusion Delineator Posts and Guardrail Markers shall consist of a single curve, C-shaped thermoplastic extrusion a minimum of 3.75 inches wide, with 0.160 inch (typical) walls, comprised of a uniformly curved profile with a 3.0” radius. All delineator posts shall be capable of sustaining a minimum of ten (10) direct wheel-over impacts at 60 MPH (100 KPH) without damage to the post or the reflective sheeting applied to the post. All posts shall be constructed of UV-stabilized thermo-plastic polycarbonate (PC) for superior durability and weathering, conforming to the following material specifications: Property ASTM Test Results Specific Gravity (typical) D 792 1.20 Hardness (min., R-scale) D 785 100 Water Absorption, 24 hours, 73 F D 570 0.576 Tensile Elongation @ break (min. %) D 638 30 % Izod Impact, 1/8” Notched, (ft. lbs./in.)
