(a) capable of traveling at a uniform rate of speed, both uphill and downhill, to produce a uniform application of the Two Reactive Component material and capable of following straight lines and making normal curves in true arcs . (b) capable of applying reflective elements to the surface of the completed stripe by an automatic reflective element dispenser attached to the striping machine such that the reflective elements are dispensed closely behind the installed line . Use a reflective element dispenser equipped with an automatic cut-off control that is synchronized with the cut-off of the material and applies the reflective elements in a manner such that the reflective elements appear uniform on the entire traffic stripes and markings surface with, 50 to 60% embedment . (c) capable of providing the manufacturer ' s recommended mixing ratio between the components in a thorough and consistent manner. 709-4 Application. 709-4 . 1 General : Remove existing pavement markings , such that scars or traces of removed markings will not conflict with new stripes and markings by a method approved by the , Engineer. Before applying traffic stripes and markings , remove any material by a method approved by the Engineer that would adversely affect the bond of the traffic stripes . Offset longitudinal lines at least 2 inches from construction joints of portland cement concrete pavement . Apply traffic stripes or markings only to dry surfaces , and when the ambient air and surface temperature is at least 40°F and rising . Do not apply pavement markings when winds are sufficient to cause spray dust. Apply striping to the same tolerances in dimensions and in alignment specified in 710 - 5 . When applying traffic stripes and marking over existing markings , ensure that not more IN than 2 inches on either end and not more than 1 inch on either side of the existing line is visible . Apply the Two Reactive Component product to the pavement in accordance with the manufacturer ' s instructions or as directed by the Engineer . IN Conduct field tests in accordance with FM 5 - 541 . Remove and replace traffic stripes and markings not meeting the requirements of this Section at no additional cost to the Department . NN Apply all final pavement markings prior to opening the road to traffic . 709-4 .2 Thickness : Apply traffic stripes and markings to attain a minimum wet film thickness in accordance with the manufacturer' s recommendations as identified on the QPL system . 7094 .3 Retroreflectivity : Apply white and yellow traffic stripes and markings that will attain an initial retroreflectivity of not less than 450 mcd/lx mZ and not less than 350 mcd/lx • mZ , respectively for all longitudinal and transverse lines . Measure , record and certify on the Department approved form and submit to the Engineer, the retroreflectivity of white and yellow pavement markings in accordance with Florida Method FM- 5 - 541 . The Department reserves the right to test the markings within 3 days of receipt of the Contractor ' s certification . Failure to afford the Department opportunity to test the markings will result in non-payment . The test readings should be representative of the Contractor ' s striping performance . If the retroreflectivity values measure below values shown above , the striping will be removed and reapplied at the Contractor ' s expense . 709-4 .4 Color : Use materials that meet the requirements of 971 - 1 .
