j i (d) The controller in the control panel shall be able to remember messages during non - powered conditions. (e) The controller shall allow the operator to generate additional messages on site via the keyboard. (f) For a PCMS using Flip -Disk technology, the controller shall have the capability to provide a stipulated default message upon loss of controller function. (g) All messages shall be flashed or sequenced. In the sequence mode, the controller shall have the capability to sequence three line messages during one cycle. 990 -5 Removable Tape. 990 -5.1 Composition: The pavement stripes and markings shall consist of high quality plastic materials, pigments, and glass spheres or other retroreflective materials uniformly distributed throughout their cross - sectional area, with a reflective layer of spheres or other retroreflective material embedded in the top surface. No foil type materials shall be allowed. 990 -5.2 Skid Resistance: The surface of the stripes and markings shall provide a minimum skid resistance value of 35 BPN (British Pendulum Number) when tested according to ASTM E 303. Bike lane symbols and pedestrian crosswalks shall provide a minimum skid resistance value of 55 BPN. 990 -5.3 Thickness: The Qualified Products List will list the specified thickness of each approved product. 990 -5.4 Durability and Wear Resistance: When properly applied, the material shall provide neat, durable stripes and markings. The materials shall provide a cushioned resilient substrate that reduces sphere crushing and loss. The film shall be weather resistant and, through normal wear, shall show no significant tearing, rollback or other signs of poor adhesion. Durability is the measured percent of pavement marking material completely removed from the pavement. The pavement marking material line loss must not exceed 5.0% of surface area. 990 -5.5 Conformability and Resealing: The stripes and markings shall be capable of conforming to pavement contours, breaks and faults under traffic at pavement temperatures recommended by the manufacturer. The film shall be capable of use for patching worn areas of the same types of film in accordance with the manufacturer's recommendations. 990 -5.6 Tensile Strength: The stripes and markings shall have a minimum tensile strength of 40 psi [275 kPa] when tested according to ASTM D 638. A rectangular test specimen 6 by 1 by 0.05 [150 by 25 by 1.5 mm] minimum thickness shall be tested at a temperature range of 40 to 80 °F [21 to 27 °C] using a jaw speed of 0.25 inch /min [6 mm /min]. 990 -5.7 Elongation: The stripes and markings shall have a minimum elongation of 25% when tested in accordance with ASTM D 638. 990 -5.8 Plastic Pull test: The stripes and markings shall support a dead weight of 4 lb [ 1 .8 kg] for not less than five minutes at a temperature range of 70 to 80 °F [21 to 27 °C]. Rectangular test specimen size shall be 6 by 1 by 0.05 inch [1 50 by 25 by 1.5 mm] minimum thickness. 990 -5.9 Adhesive: Precoat removable tape with a pressure sensitive adhesive capable of being affixed to asphalt concrete and portland cement concrete pavement surfaces without the use of heat, solvents, and other additional adhesives or activators. Use an adhosive that exhibits excellent sheer characteristics and minimal tensile March 2007 01000 -205 03- 4122.D
