Upon curing, these <br />materials shall produce an adherent, reflective pavement marking capable of resisting <br />deformation by traffic. The manufacturer shall have the option of formulating the material <br />according to his own specifications. However, the requirements delineated in this <br />Specification and Section 710 shall apply regardless of the type of formulation used. The <br />material shall be free from all skins, dirt and foreign objects. <br />971-4.2 Composition: <br /> <br />..., <br /> <br />. <br /> <br />.., <br /> <br />. <br /> <br />f""I <br /> <br />. <br /> <br />Component Test Method Criteria <br />Total Solids, by weight ASTM D 2369 75 % minimum <br />Pigments, by weight ASTM D 3723 57% minimum <br />Vehicle Solids, % on Vehicle" 40% minimum <br />Ti02, Type II Rutile (white paint ASTM D 476 1.5 Ib/gal [0.18 kg/L] minimum <br />only) <br />Volatile Organic Content, (VOC) ASTM D 3960 150 g/l maximum <br /> <br />..., <br /> <br />. <br /> <br />.. <br />. <br /> <br />,..., <br />. <br /> <br />971-4.3 Physical Requirements: The material shall meet the following criteria: <br /> <br />. <br /> <br />Property Test Method Minimum Maximum <br />Density ASTM D 1475 13.5 :t 0.37 Ib/gal N/A <br /> [1.62 + 0.17 kg/L] <br />Consistency at 1700F ASTM D 562 80 KU 100 KU <br />[77OC] <br />Fineness of Grind ASTM D 1 21 0 2 (HS) [75 11m] 3(HS) [65 11m] <br />Dry Opacity at Fed Std 141 a 0.96 <br /> - <br />5 mils [127 11m] WFT Method 41 21 <br />Bleed Ratio Fed Spec TT-P-85D 0.95 - <br />Flexibility Fed Spec TT-P-115D Pass - <br />Abrasion Resistance 961-10.6.3 Pass - <br /> <br />II <br /> <br />. <br /> <br />r, <br /> <br />" <br /> <br />. <br /> <br />r-I <br /> <br />. <br /> <br />P"'I <br /> <br />- <br /> <br />971-4.3.1 Set To Bear Traffic Time: When applied at the temperatures and <br />thickness specified by Section 710, the material shall set to bear traffic in not more than <br />two minutes. <br />971-4.3.2 Abrasion Resistance: Test four samples per LOT using a Taber <br />Abrader. The paint shall be applied to specimen plates using a drawdown blade having a <br />clearance of 26 mils [660 11m]. Air dry each sample for 30 minutes and bake at 2200F <br />[1050C] for 18 hours. Clean with a soft brush and weigh each sample. Abrade samples for <br />1,000 cycles with 1.1 Ib [500 g] weights and CS-10 wheels. Clean the samples with a <br />soft brush and weigh again. The average weight loss for the four plates shall not exceed <br />0.178 oz [50 mg] per plate. <br />971-4.3.3 Retroreflectivity: The white and yellow pavement markings shall <br />attain an initial retroreflectance of not less than 300 mcd/lx.m2 and 250 mcd/lx.m2, <br />respectively. The retroreflectance of the white and yellow pavement markings at the end <br />of the six month service life shall not be less than 150 mcd/lx.m2. <br /> <br />..., <br /> <br />. <br /> <br />-, <br /> <br />- <br /> <br />r-, <br /> <br />. <br /> <br />II <br /> <br />. <br /> <br />..., <br /> <br />. <br /> <br />II <br /> <br />09/09 <br /> <br />01 000-1 90 <br /> <br />03-4122.F <br /> <br />. <br />
