In the sequence mode, the <br />controller shall have the capability to sequence three line messages during one cycle. <br /> <br />. <br /> <br />..., <br /> <br />. <br /> <br />. <br /> <br />.... <br /> <br />. <br /> <br />990-5 Removable Tape. <br />990-5.1 Composition: The pavement stripes and markings shall consist of high <br />quality plastic materials, pigments, and glass spheres or other retroreflective materials <br />uniformly distributed throughout their cross-sectional area, with a reflective layer of <br />spheres or other retroreflective material embedded in the top surface. No foil type materials <br />shall be allowed. <br />990-5.2 Skid Resistance: The surface of the stripes and markings shall provide a <br />minimum skid resistance value of 35 BPN (British Pendulum Number) when tested <br />according to ASTM E 303. Bike lane symbols and pedestrian crosswalks shall provide a <br />minimum skid resistance value of 55 BPN. <br />990-5.3 Thickness: The Qualified Products List will list the specified thickness of <br />each approved product. <br />990-5.4 Durability and Wear Resistance: When properly applied, the material shall <br />provide neat, durable stripes and markings. The materials shall provide a cushioned resilient <br />substrate that reduces sphere crushing and loss. The film shall be weather resistant and, <br />through normal wear, shall show no significant tearing, rollback or other signs of poor <br />adhesion. Durability is the measured percent of pavement marking material completely <br />removed from the pavement. The pavement marking material line loss must not exceed <br />5.0% of surface area. <br />990-5.5 Conformability and Resealing: The stripes and markings shall be capable of <br />conforming to pavement contours, breaks and faults under traffic at pavement <br />temperatures recommended by the manufacturer. The film shall be capable of use for <br />patching worn areas of the same types of film in accordance with the manufacturer's <br />recommendations. <br />990-5.6 Tensile Strength: The stripes and markings shall have a minimum tensile <br />strength of 40 psi [275 kPa] when tested according to ASTM 0 638. A rectangular test <br />specimen 6 by 1 by 0.05 [150 by 25 by 1.5 mm] minimum thickness shall be tested at a <br />temperature range of 40 to 800F [21 to 2JDC] using a jaw speed of 0.25 inch/min [6 <br />mm/min] . <br />990-5.7 Elongation: The stripes and markings shall have a minimum elongation <br />of 25% when tested in accordance with ASTM 0 638. <br />990-5.8 Plastic Pull test: The stripes and markings shall support a dead weight of 4 <br />Ib [1.8 kg] for not less than five minutes at a temperature range of 70 to 800F [21 to <br />270C]. Rectangular test specimen size shall be 6 by 1 by 0.05 inch [150 by 25 by 1.5 mm] <br />minimum thickness. <br />990-5.9 Adhesive: Precoat removable tape with a pressure sensitive adhesive <br />capable of being affixed to asphalt concrete and portland cement concrete pavement <br />surfaces without the use of heat, solvents, and other additional adhesives or activators. <br />Use an adhesive that exhibits excellent sheer characteristics and minimal tensile <br /> <br />.... <br /> <br />. <br /> <br />r"\ <br /> <br />. <br /> <br />r"1 <br /> <br />. <br /> <br />..., <br /> <br />. <br /> <br />.., <br />. <br /> <br />M <br /> <br />. <br /> <br />n <br /> <br />. <br /> <br />,.., <br /> <br />. <br /> <br />-, <br />. <br /> <br />..., <br /> <br />. <br /> <br />,.., <br /> <br />. <br /> <br />,.., <br /> <br />. <br /> <br />r-I <br /> <br />. <br /> <br />,.., <br /> <br />09/09 <br /> <br />01000-205 <br /> <br />03-4122.F <br /> <br />. <br />
