710-4 Application .
710-4.1 General: Remove existing pavement markings, such that scars or traces of
removed markings will not conflict with new pavement markings, by a method approved by the Engineer. Before applying pavement markings, remove any material that would adversely affect the bond of the pavement markings by a method approved by the Engineer . Apply standard paint to dry surfaces only, and when the ambient air and surface temperature is at least 40ºF and rising. Apply durable paint to dry surfaces only. Do not apply durable paint when the ambient air and surface temperature is below 50°F, relative humidity is above 80% or when the dew point is within 5°F of the ambient air temperature . Do not apply painted pavement markings when winds are sufficient to cause spray dust. Apply painted pavement markings, having well defined edges, over existing pavement markings such that not more than 2 inches on either end and not more than 1 inch on FY 2023-24 Return to Table of Contents either side is visible. When stencils are used to apply symbols and messages, the areas covered by the stencil reinforcing will not be required to be painted. Mix the paint thoroughly prior to pouri ng into the painting machine. Apply paint to the pavement by spray or other means approved by the Engineer. Conduct field testing in accordance with FM 5-541. Remove and replace painted pavement markings not meeting the requirements of this Section at no additional cost to the Department. Apply all pavement markings prior to opening the road to traffic.
710-4.1 1 Painted Pavement Markings ( Final Surface ): On concrete surfaces or
newly constru cted asphalt , the painted pavement markings (final surface) will include one application of standard paint applied to the final surface . For center line and edge line rumble strip installations where the pavement marking is placed within the grinding , apply a second application of standard paint within 24 hours of each day’s grinding operation. Do not apply final surface paint for bicycle arrows or bicycle messages, 24 inch longitudinal bars in special emphasis crosswalks, or route shields where pref ormed thermoplastic will be applied.
710-4.2 Thickness: Apply standard paint to attain a minimum wet film thickness in
accordance with the manufacturer’s recommendations. Apply durable paint to attain a minimum wet film thickness of 0.025 inches or 25 mils. Measure, record, and certify on a Department approved form and submit to the Engineer, the thickness of white and yellow durable paint pavement markings in accordance w ith FM 5-541.
710-4.3 Retroreflectivity: Apply white and yellow standard paint that will attain an
initial retroreflectance of not less than 300 mcd/lx·m2 and not less than 250 mcd/lx·m2, respectively. Apply white and yellow durable paint that will attain an initial retroreflectance of not less than 450 mcd/lx·m2 and not less than 300 mcd/lx·m2, respectively . Black pavement markings must have a retroreflectance of less than 20 mcd/lx·m2. Measure, record and certify on a Department approved form and submi t to the Engineer, the retroreflectivity of white and yellow pavement markings in accordance with FM 5-541. The Department reserves the right to test the markings within three days of receipt of the Contractor’s certification. Failure to afford the Depar tment opportunity to test the markings will result in non -payment. The test readings should be representative of the Contractor’s pavement marking performance. If the retroreflectivity values measure below values shown above, reapply the pavement marking at no additional cost to the Department. For standard paint, ensure that the minimum retroreflectance of white and yellow pavement markings are not less than 150 mcd/lx·m2. If the retroreflectivity values for standard paint fall below the 150 mcd/lx·m2 value within 180 days of initial application, the pavement marking will be reapplied at the Contractor’s expense. If the retroreflectivity values for durable paint fall below the initial values of 450 mcd/lx·m2 value for white and 300 mcd/lx·m2 for yellow within 180 days of initial application, the pavement marking will be reapplied at the Contractor’s expense.
710-4.4 Color: Use paint material that meets the requirements of 971 -1.
710-4.5 Glass Spheres: Apply glass spheres on all pavement marki ngs immediately and
uniformly following the paint application. The rate of application shall be based on the manufacturer’s recommendation. FY 2023-24 Return to Table of Contents For longitudinal durable paint markings, apply a double drop of Type 1 and Type 3 glass spheres. For transverse du rable paint markings, apply a single drop of Type 3 glass spheres. The rate of application shall be based on the manufacturer’s recommendation.
710-5 Tolerances in Dimensions and in Alignment.
Establish tack points at appropriate intervals for use in al igning pavement markings , and set a stringline from such points to achieve accuracy.
710-5.1 Dimensions:
710-5.1 1 Longitudinal Lines: Apply painted skip line segments with no more
than plus or minus 12 inches variance, so that over -tolerance and under-tolerance lengths between skip line and the gap will approximately balance. Apply longitudinal lines at least 2 inches from construction joints of portland cement concrete pavement.
710-5.1 2 Transverse Markings, Gore Markings, Arrows, and Messages :
Apply paint in multiple passes when the marking cannot be completed in one pass, with an overall line width allowable tolerance of plus or minus 1 inch.
710-5.1 3 Contrast Lines: Use black paint to provide contrast on concrete or
light asphalt pavement , when specified by the Engineer. Apply black paint in 10 foot segments following each longitudinal skip line.
710-5.2 Alignment: Apply painted pavement markings that will not deviate more than
1 inch from the stringline on tangents and curves one degree or less. Apply painted pavement markings that will not deviate more than 2 inches from the stringline on curves greater than one degree. Apply painted edge markings uniformly, not less than 2 inches or more than 4 inches from the edge of pavement, without noticeable breaks or deviations in alignment or width. Remove and replace at no additional cost to the Department , pavement markings that deviate more than the above stated requirements.
710-5.3 Correction Rates: Make corrections of variations in width at a maximum rate of
10 feet for each 0.5 inch of correction. Make corrections of variations in alignment at a maximum rate of 25 feet for each 1 inch of correction, to return to the stringline.
710-6 Contractor’s Responsibility for Notification.
Notify the Engineer prior to the placement of the materials. At the time of notification, submit a certification to the Engineer with the APL number and the batch or Lot numbers of the paint and glass spheres to be used.
710-7 Protection of Newly Applied Pavement Markings.
Do not allow traffic onto or permit vehicles to cross newly applied pavement markings until they are sufficiently dry. Remove and replace any portion of the pavement markings damaged by passing traffic or from any other cause, at no additional cost to the Department.
