Section 623 Section 623 Payment will be made under: 623-A: Drainage Wicks - per linear foot SECTION 625 - PAINTED TRAFFIC MARKINGS
625.01 Description . This work consists of furnishing materials and applying
reflectorized painted traffic markings and high build painted traffic markings in reasonably close conformity with these specifications and the details shown on the plans or established.
625.02 Materials . Paint shall be the color specified and shall meet the applicable
requirements of Section 710. Application of permanent painted traffic markings shall require Class B (High-Visibility) glass beads. Otherwise, Class A (Standard) glass beads shall be required. Glass beads shall meet the requirements of Subsection 720.01. Blue - ADA marking material shall meet the requirements of Section 710 with the exception that the color shall be Blue - ADA.
625.03 Construction Requirements .
625.03.1 Equipment . All paint shall be applied by approved mechanical equipment
providing constant agitation of paint, traveling at controlled speeds, with one or more paint "guns" synchronized to begin and cut off paint flow automatically for skip lines, and subject to manual control for continuous lines of varying length. The machine, or a separate machine, shall be equipped with a glass bead dispenser adjusted and so synchronized with the paint applicator as to distribute the beads uniformly on the painted lines within 10 seconds. Calibration charts and devices for measurement of tanks shall be provided by the Contractor for determining the quantity being applied. All painting equipment and operations shall be under the control of an experienced technician thoroughly familiar with the equipment, materials, and marking layouts.
625.03.2 Preparation of Surface . All areas to be painted shall be thoroughly cleaned.
Cleaning may be done by hand brooms, rotary brooms, air blast, scrapers, or whatever combination of equipment is necessary to clean the pavement thoroughly without damage to the surface. Before edge striping, particular care shall be taken to remove all vegetation, loose soil, and the like from the area to be painted. Should other methods fail, the surface shall be wetted with a water jet and scrubbed as necessary to dislodge all foreign material. After washing, the surface shall be allowed to dry thoroughly, and all films of dried mud apparent after surface drying shall be removed before application of paint. Painting shall follow as closely as practicable after the surf ace has been cleaned and dried, but no paint shall be applied until the surface has been insp ected and permission gi ven to proceed. The cost for preparing the surface sh all be included in the contract unit prices for the marking items. Upon request, the Engineer will establish control points for markings, by type and color, at necessary intervals not to exceed 600 feet . The Contractor shall preserve and apply markings in conformity with control points established.
625.03.3 Application . The paint shall be applied when the ambient temperature is no less
than 50oF, the pavement surface is properly prepared and the temperature of the pavement surface is no less than 50oF. For four-inch temporary traffic stripe, paint and Class A glass beads shall be uniformly applied at the rate of not less than one gallon of paint and six pounds of beads per 264 linear feet of four-inch stripe. For six-inch permanent traffic stripe, paint and Class B glass beads shall be uniformly applied at the rate of not less than one gallon of paint and twelve pounds of beads per 176 linear feet of six-inch stripe. For six-inch permanent high build traffic stripe, paint and Class B glass beads sha ll be uniformly applied at the rate of not less than one gallon of paint and twelve pounds of beads per 140 linear feet of six-inch stripe. The length and width of lines shall be within a tolerance of plus or minus three inches and plus or minus 1/8 inch, respectively. For skip markings, the tolerance for intervals shall not exceed the line length tolerance. Markings applied at less than minimum material rates, deviating from true alignment by more than one inch in 50 feet, exceeding stipulated length and width tolerances, and showing light spots, faulty distribution of beads, smears, or other deficiencies or irregularities shall be removed and replaced. Removal methods shall be in accordance with Subsection 619.03.2.
625.03.4 Protection . The newly painted markings shall be protected so that, insofar as
possible, paint will not be picked up by the tires of passing vehicles. Warning signs shall be placed at the beginning of a wet line and at points well in advance of the marking equipment. For the benefit of the Contractor, small flags or other similarly effective small objects may be placed near freshly applied lin es at frequent interval s to reduce crossings by traffic. Damaged portions of stripes sha ll be effaced and replaced by the Contractor at no additional cost to the State. Operations shall be conducted so that traffic can move without undue hindrance. When public traffic is being maintained, warning signs at the starting end shall be moved forward as sections of stripe dry sufficiently to prev ent pick-up under traffic. Reference is made to Subsection 710.02.2.2 for the particular paint involved. 625.03.5--Detail Traffic Stripe . Detail traffic stripe shall be those short stripes, exclusive of lane and edge striping of the main facility, at exit and entrance ramps, turnouts, turn bays, and other locations indicated on the plans. When shown on the plans or directed by the Engineer, detail stripe of the color, width, and length shall be placed in accordance with the provisions and requirements of this section.
625.03.6 Legend . Legend shall be applied by the use of templates cut to the dimensions
shown on the plans, or by other methods appr oved by the Engineer that will provide a clean cut, uniform, and workmanlike appearance. All other requirements for legend shall be in accordance with the app licable materials and construction requirements of this section. Legend that fails to have a uniform, satisfactory appearance either by day or by night shall be corrected by the Contractor or removed and replaced at no additional cost to the State.
625.04 Method of Measurement . Painted traffic markings, of the type specified, will be
measured by the linear foot, square foot, or mile, from end-to-end of individual stripes. In the case of skip lines the m easurement will include skips. The length used to measure centerline, lane lines and edge stripes will be the horizontal length computed along the stationed control line. Detail traffic stripe will be measured by the linear foot from end-to-end of individual stripes. Measurement will be made along the surface of each stripe and will exclude nominal skip intervals where specified. Stripes more than six inches in width will be converted to equivalent lengths of six-inch stripe. Legend, which includes railroad markings, pedestrian crosswalks and stop lines, will be measured by the square foot or linear foot. Pay areas of individual letters and symbols will usually be shown on the plans and measured by the square foot. Transverse railroad bands, pedestrian crosswalks and stop lines will generally be measured by the linear foot, in which case, stripes more than six inches in width will be converted to equivalent lengths of six-inch widths.
625.05 Basis of Payment . Painted traffic markings will be paid for at the contract unit
price per mile, linear foot, or square foot as applicable, which price shall be full compensation for co mpleting the work. Payment will be made under: 625-A: Traffic Stripe, Skip White * - per linear foot or mile 625-B: Traffic Stripe, Skip Yellow * - per linear foot or mile 625-C: Traffic Stripe, Continuous White * - per linear foot or mile 625-D: Traffic Stripe, Continuous Yellow * - per linear foot or mile 625-E: Detail Traffic Stripe * ** - per linear foot 625-F: Legend * ** - per square foot or linear foot * Indicate High Build if applicable ** Indicate Blue - ADA if applicable SECTION 626 - THERMOPLASTIC TRAFFIC MARKINGS
626.01 Description . This work consists of furnishing materials and placing thermoplastic
pavement markings of the type specified in reasonably close conformity with these specifications and the details shown on the plans or established. All pavement marking material, excluding edge lines over rumble strips, shall be applied using the extrusion/ribbon method. Edge lines placed over rumble strips shall be applied using the atomization/spray method.
