Specifications include, but are not limited to: Design - The delineator post shall consist of a modified T-shaped tubular post a minimum of 3.00 inches wide by 2.00 inches deep, with 0.125 inch (min.) walls, comprised of flat front and curved rear surfaces and sides to create areas of opposing compression stresses on the inner and outer walls when impacted resulting in superior rebound. All delineator posts shall be capable of sustaining a minimum of twenty five (25) direct wheel-over impacts at 60 MPH (100 km/h) without damage to the post or the reflective sheeting applied to the post. All posts shall be easily replaceable. All posts shall be constructed of UV-stabilized thermo-plastic polyurethane (TPU) for superior durability, conforming to the following material specifications: Property ASTM Test Results Specific Gravity (min.) D 792 1.10 Hardness (min.) D 2240 80 A Tear Strength (min PSI) D 624, Die C 600 Tensile Strength @ yield, (min PSI) D 412 4,000 Tensile Elongation @ break (min. %) D 412 600 Cold Temp. Impact Test (-7° F) FL/DOT Pass Florescent and Standard Colors - Delineator posts shall be constructed of UV-stabilized polymers and colors. The color shall be white solid throughout and stabilized to resist UV degradation. Reflective Sheeting - All posts shall have retro-reflective sheeting applied. The minimum reflective sheeting shall be two (2) 4-inch wide wraps of sheeting, one (1) inch down from the top of the post with a two (2) inch gap between wraps. The sheeting shall be Reflexite ® AR 1000 cube-corner micro-prismatic reflective sheeting for superior brightness, scratch resistance and durability. The color of sheeting shall be green. Lengths - Delineator posts shall be available in lengths to 48 inches, as specified in the construction plans or procurement details. NCHRP 350 Acceptance - The delineator posts shall be fully crash-tested on the AASHTO’s NTPEP Test Deck and meet requirements for Category 1 devices as specified in NCHRP Report # 350. All delineator posts shall have the acceptance of the U.S. Department of Transportation, Federal Highway Administration. Certifications of acceptance to these standards must be supplied by the manufacturer upon request. Construction. Delineator posts shall be secured to the roadway with removable and reusable one-piece anchor bolts with a finished hex head, integral washer, dual lead threads and chamfered tip. One-piece bolts shall be used to eliminate improper assembly; dual-thread bolts shall be used to prevent bolts spinning in holes when tightened. Screw Bolts shall be 3/8” x 4” carbon steel, able to fasten to concrete, asphalt, block and brick. All delineator posts shall be completely removable with standard power tools. On bridges, posts shall be adhered to the roadway with approved bituminous adhesive or pressure-sensitive synthetic butyl rubber pads, min. 0.125” thick.
