A.Cold Applied Plastic Pavement Marking and Legends: 1.Prefabrication: Prefabricated legends and symbols will conform to the applicable shapes and sizes as outlined in the current edition of the MUTCD. 2.Width Tolerance: Width will be as specified with a tolerance of ±1/8 inch. 3.Surface and Air Temperature: The surface will be 70°F minimum, and ambient air temperature of 60°F minimum and rising, at a season when daily highs are above 70°F and lows are above 40°F. If the manufacturer’s recommendations allow for installation at temperature below the minimum required by this section, the Contractor may install the material in accordance with the manufacturer’s recommendations, including any additional adhesives. 4.Pavement Condition: Pavement must be dry and free of dirt, dust, and oily substances. 5.Application Instructions: The manufacturer will supply proper application instructions and will identify activators and adhesives which are to be used. An adhesive activator supplied by the manufacturer will be utilized on applications of this material, except on newly installed asphalt when the surface temperature is 80°F or above. A copy of the application instructions will be provided to the Engineer prior to use. The plastic markings will be manufactured and packaged in a manner, which will permit storage at normal temperatures for up to one year after purchase. 6.Lane Lines : Lane lines will not be placed over a longitudinal pavement joint and will not be installed closer than 1½ inches from the joint. Lane lines will not deviate more than 1 inch per 200 feet, nor will any deviations be abrupt. 7.Bonding: To ensure a uniform bond of material to asphalt or concrete surfaces after initial laydown, rolling of the material with a truck wheel, car wheel, or heavy hand roller in accordance with the manufacturer’s recommendations is required. 633 Page 4338.Molding and Sealing: The material will mold to the pavement contours, breaks, and faults by the action of traffic. The material will have resealing characteristics, which enable the material to fuse with itself and with previously applied marking materials of the same composition without externally applied tackifiers or adhesives. 9.Waste Disposal: It will be the responsibility of the Contractor to provide for disposal of empty material cartons, liner papers, and other waste. B.Pavement Marking Paint and Beads: Pavement marking paint will be applied by machine. On special areas and markings that are not adaptable to machine application, hand application will be permitted. The paint will be used as furnished by the manufacturer. Thinner or diluent will not be added. The paint will be thoroughly mixed in the original container before it is transferred to the tank of the spraying equipment. Filling tanks, pouring paint, or cleaning of equipment will not be allowed on the pavement. The pavement marking will be applied during daylight hours when the ambient air temperature is above 40°F and the road surface is dry. The pavement will be cleaned of dirt, loose stones, and other foreign material before the paint is applied. The paint applicator will be a self-propelled spraying machine. The paint applicator will be capable of applying marking materials in a solid and intermittent line pattern, according to the details in the plans. The equipment will be capable of placing lines on the left and right sides with each line in a solid or intermittent pattern and each gun applying 4 to 8 inches wide. The left carriage will simultaneously place a dashed marking, a solid marking and a dashed marking, or two solid markings as detailed in the plans. The paint will be applied at a maximum speed as recommended by the paint applicator manufacturer and will not exceed 13 miles per hour. The paint applicator will be capable of applying glass beads in a pressurized system, synchronized with the spray guns, uniformly across the entire painted line. All guns on the spray carriages will be in full view of the operator during operation. The equipment in the striping train will be capable of displaying a left or right Type C sequential chevron. The Type C sequential chevrons will meet current MUTCD standard for minimum size, legible distance, number of elements and other specifications. All traffic control items that are mounted on the equipment will be incidental to the other contract items. No separate payment will be made. During pavement marking operations on sections of roadway open to traffic, the Contractor will protect the markings from tracking either by placing suitable traffic control devices or by utilizing a shadow vehicle. The work will be arranged such that half of the traveled roadway will be open to traffic at all times. The Contractor will take the steps necessary to ensure that the permanent pavement markings will match the markings on the existing surface. 633 Page 434Tolerances: 1.The length of the painted line will not vary more than plus or minus 3 inches from the plans requirement. 2.The width of the painted line will not vary more than plus or minus 1/2 inch from the plans requirement. 3.The length of a 40 foot cycle length consisting of a 10 foot dashed line and a 30 foot gap will not vary more than 3 inches. 4.The alignment from the plans requirement or existing markings will not vary more than plus or minus 2 inches. 5.The maximum longitudinal deviation from the existing markings at either end of the painted roadway segment will not vary more than plus or minus 6 inches. 6.Lane lines will not deviate more than 1 inch per 200 feet, nor will any deviations be abrupt. The Contractor may be required to remove and replace pavement markings not meeting the specifications and tolerances at no additional expense to the Department. Removal methods will minimize damage to the surface and will be approved by the Engineer The Contractor will apply the pavement marking paint, glass beads, and bonded core reflective elements (if required) at the rates specified in the plans. Restriping of pavement markings to meet this requirement and to provide a quality retroreflective line will be at the expense of the Contractor with no additional cost to the Department. Sections to be restriped will be determined by the Engineer. The paint will be capable of being applied at a paint temperature up to 160°F. When applied with glass beads at pavement temperatures above 45°F and at a relative humidity of up to 75%, the paint will dry to a no-track condition within 3 minutes. C.Grooving for Cold Applied Plastic Pavement Marking: The equipment will be capable of performing uniform grinding for alignment and depth. The grooving will be performed by a self-propelled machine equipped with gang mounted specially prepared circular diamond blades on a turning head. The equipment will be capable of grooving the total width of the groove in one pass or be capable of grooving uniform depths with multiple passes. The equipment will be capable of grooving double lines simultaneously or parallel lines to a uniform depth with two passes. If damage to joints, joint sealant material, backer rod, etc. occurs, the grooving operation will be stopped, and modifications will be made to the grooving operation to prevent further damage. Damage caused to joints, the joint sealant material, backer rod, etc. will be repaired or replaced by the Contractor, as directed by the Engineer. No additional payment will be made for the repair work or any reapplication of the pavement marking in the area of the repair. 633 Page 435The bottom of the groove will be uniform and free of loose material. The groove will be flat and of uniform depth for the entire width of the groove. The grooving will be performed within the following specifications and tolerances: Description Specification Tolerance Depth of Groove Marking Thickness + 15 mils + 5 mils Width of 4 inch Groove 4½ inches ± 1/8 inch Width of 6 inch Groove 6½ inches ± 1/8 inch Width of 8 inch Groove 8½ inches ±1/8 inch Width of 12 inch Groove 12½ inches ±1/8 inch Width of 24 inch Groove 24½ inches ± 1/8 inch Length of Skip Lines 10 foot 6 inches ± 3 inch Tapers at ends of lines 6 to 9 inches Between Double Lines 4 inches ± 1/2 inch The grooving alignment and straightness tolerances will be the same as required for the cold applied plastic pavement marking as specified in Section 633.3 A.6. If the groove is exposed to traffic or adverse weather conditions overnight, the Contractor will sand blast the groove prior to priming and applying tape. Existing grooves not meeting the required depth will be re-grooved to the required depth. In areas where the existing groove meets the required depth and existing markings are still in place, the Contractor will remove the existing marking by light grinding or sand blasting or both. The grooving, light grinding, and sand blasting operations will provide the surface preparation required for the application of the new cold applied plastic pavement markings.
