Pth-10 Thermoplastic traffic line paint shall be a reflectorized thermoplastic pavement striping material applied to the road surface in a molten state by mechanical means. It shall have a surface application of glass beads which, upon cooling to normal pavement temperature, will produce an adherent reflectorized stripe of the specified thickness and width, and will be resistant to deformation by traffic. The material shall contain at least20 percent by weight of glass beads in the white and yellow paints and at least 12 percent titanium dioxide in the white paint. The material, when applied at a temperature range of 4000F to 4250F (2000C to 2200C) and a thickness of 90 to 125 mils (2300 to 3200µm), shall set to bear traffic in not more than 2 minutes when the air temperature is 500F (100C) and not more than 10 minutes when air temperature is 900F (320C). 210-1.6.3 Rapid Dry White, Yellow, or Black Traffic Line Paint. Rapid dry white, yellow, or black traffic paint shall dry to a condition so that there will be no traffic pickup in 30 seconds, and which shall be completely dry in not more than 3 minutes when preheated to 430C to 820C (1100F to 1800F) in proper equipment before application. The material shall be applied at the film thickness indicated in 310-5.6.5. The “no traffic pickup” time shall be determined by ASTM D 711. 210-1.6.4 Ready-Mixed Traffic Stripe Paints. Where ready-mixed paints are specified, they shall be suitable for use on either asphalt concrete or portland cement concrete. 210-1.6.5 Reflective Material. Reflective material shall consist of glass beads added to the surface of the final coat of paint prior to setting, so that the beads have proper adhesion. Special care shall be taken with rapid dry paint and thermoplastic materials. 1 Change No. 204NS (ESSApproved060611) Glass beads shall conform to California State specification8010-71L-22 and shall be mechanically applied at a rate of 6 to 8 pounds of beads per gallon (0.7 to 1.0 kg of beads per liter) of paint, curbs and crosswalks by use of a dispensing device developed for this purpose or other methods approved by the Engineer. The Engineer may authorize the use of paint containing pre-mixed glass beads. The type, gradation, quantity, and quality of the pre-mixed glass beads shall be approved prior to the manufacture of the paint. In addition to the specified pre-mixed beads, 0.25 to 0.35 kilograms of beads per liter (2 to 3 pounds of beads per gallon) of paint shall be mechanically applied when the paint is applied. If thermoplastic paint is required, glass beads may be added directly to the combined pigment, filler, and resin in accordance with 210-1.6.1. However, prior to setting, all thermoplastic paint and surfaces shall receive an additional application of a least 1 pound of glass beads per gallon (0.12 kilograms of beads per liter) of paint. 210-1.6.6 Air Pollution. All paint shall meet the requirements of the appropriate air pollution control district. 210-1.7 Test Reports and Certification. At the time of delivery of each shipment of material, the Contractor shall, upon request, deliver to the Engineer certified copies of the manufacturer’s test reports. The test report shall indicate the name of the manufacturer, type of material, date of manufacture, quantity, State Specification number, manufacturer’s lot or batch number, and results of the required tests. The test report shall be signed by an authorized representative of the manufacturer. The certified test reports and the testing required in connection therewith shall be a no cost to the Agency. SECTION 214 - PAVEMENT MARKERS 214-1 GENERAL. The following specifications set forth the requirements of reflective and nonreflective pavement markers. The markers shall conform to the shape, dimensions, colors, sizes, and tolerances shown on the Plans. Pavement markers shall be of the type and color shown on the Plans or in the Specifications. 214-2 TYPE OF MARKERS. Pavement markers shall conform to one or more of the following types: Type A - Nonreflective White Markers Type AY - Nonreflective Yellow Markers Type B - Two-Way Clear Reflective Markers Type C - Red-Clear Reflective Markers 2 Change No. 204NS (ESSApproved060611) Type D - Two-Way Yellow Reflective Markers Type G - One-Way Clear Reflective Markers Type H - One-Way Yellow Reflective Markers Type I - Two-Way Blue Reflective Markers 214-3 SAMPLING, TOLERANCES, PACKAGING AND STORAGE. 214-3.1 Sampling. Twenty markers selected at random will constitute a representative sample for lots of 10,000 markers or less. Forty markers will constitute a representative sample for lots of more than 10,000 markers. For sampling purposes, the lot size shall not exceed 25,000 markers. 214-3.2 Tolerances. 214-3.2.1 Test Specimens. Three test specimens shall be randomly selected from the sample for each test except as noted in 214-3.2.2, and tested for compliance in accordance with these specifications. Should any one of the three specimens fail to comply with the requirements of these specifications, six additional specimens will be tested. The failure of any one of these six specimens shall be cause for rejection of the entire lot or shipment represented by the sample. 214-3.2.2 Reflectance. The entire sample of reflective pavement markers shall be tested for reflectance. The failure of 10 percent or more of the original sampling shall be cause for rejection. 214-3.2.3 Resamples. At the discretion of the Engineer, a resample may be taken consisting of double the number of samples originally taken. Tolerance for resamples shall be in the same ratio as specified above. 214-3.3 Packaging. Shipments shall be made in containers which are acceptable to common carriers and packaged in such a manner as to ensure perfect condition. Any damaged shipments shall be replaced by the Contractor. Each package shall be clearly marked as to the name of the manufacturer, type, color, quantity enclosed, lot number, and date of manufacture. 214-3.4 Storage. Markers shall be stored indoors, and shall be protected from any source of moisture both during shipment to the job site and at the job site. The markers shall be maintained at a high enough temperature as to preclude moisture condensation, and, at the time of placement, both the markers and their containers shall be dry. 214-4 NONREFLECTIVE PAVEMENT MARKERS. Types A and AY pavement markers shall consist of a heat-fired, vitreous, ceramic base and a heat-fired, opaque, glazed surface to produce the properties required in these specifications. The markers shall be produced 3 Change No. 204NS (ESSApproved060611) from any suitable combination of intimately mixed clays, shales, talcs, flints, feldspars, or other organic material which will meet the properties herein required. The markers shall be thoroughly and evenly matured and free from defects which will affect appearance or serviceability. The bottoms of the ceramic markers shall be free from gloss or glaze and shall have a number of integrally formed protrusions approximately 0.05 inch (1.5 mm) projecting from the surface in a uniform pattern of parallel rows. The tips of the protrusions shall not deviate more than 0.05 inch (1.5 mm) from a flat surface. Each protrusion shall have a face parallel to the bottom of the marker. The area of each parallel face shall be between 0.01 and 0.065 in2 (6.5 mm2 and 41.9 mm2) and combined area of these faces shall be between 2.2 and 4 in2 (1420 mm2 and 2580 mm2). The protrusions shall be circular in section. The number of protrusions should not be less than 50 or more than 200. To facilitate forming and mold release, the sides of each protrusion may be tapered. This taper shall not exceed 15 degrees from perpendicular to the marker bottom. Markers manufactured with protrusions whose diameter is less than 0.15 inch (4.0 mm) may have an additional taper not exceeding 30 degrees from perpendicular to the marker bottom and exceeding no more than one-half the total height of the protrusion. Nonreflective pavement markers shall conform to the following finish and testing requirements: a) Finish. The top surface of nonreflective markers shall be convex and the radius of curvature shall be between 3-1/2 inches (90 mm) and 6 inches (150 mm), except that the radius of the 1/2 inch (15 mm) nearest the edge may be less. Any change in curvature shall be gradual. The top and sides shall be smooth and free of mold marks, pits, indentations, air bubbles, or other objectionable marks or discolorations.
