<br />THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br /> <br />Project No. 21-1011 November 2024 025770 -3 <br />the center line stripes are being painted, all traffic shall be routed away from the painting <br />operations and the newly painted stripe. When necessary, a pilot car shall be used <br />to protect the painting operations from traffic interference. <br /> <br />J. Any portions of the stripes damaged by passing traffic or from other causes shall be <br />repainted. <br /> <br />K. Paint for temporary pavement markings shall also be used where thermoplastic <br />markings are to be applied after the asphaltic concrete has "cured." The cure time shall be <br />based on thermoplastic manufacturer's recommendations. However, in accordance <br />with FDOT requirements, asphalt shall have been in place for 30 days before <br />application of thermoplastic stripe. <br />3.2 THERMOPLASTIC TRAFFIC STRIPES AND MARKINGS <br />A. Thermoplastic pavement markings, including stripes, pavement messages, stop bars, <br />directional arrows, reflective pavement markers and other miscellaneous items, shall be <br />replaced as existed before the repair was made. The thermoplastic compound shall be <br />extruded or sprayed onto the pavement surface in a molten state by mechanical means, <br />with surface application of glass spheres, when required. Upon cooling to ambient <br />pavement temperature, the compound shall produce an adherent pavement marking of <br />specified thickness and width and capable of resisting deformation. <br />B. The colors of the compound shall be white or yellow, as existed before the repair. <br />C. Where thermoplastic markings are to be applied to concrete pavement, a sealing primer, <br />as specified in FDOT Specifications Section 711-2.2, shall be applied in advance of the <br />placing of the stripes. <br />D. The thermoplastic shall be applied to the pavement utilizing either extrusion or spray <br />application equipment. The application equipment shall be so constructed as to provide <br />continuous mixing and agitation of the material. Conveying parts of the equipment <br />between the main material reservoir and the shaping die or gun shall be so constructed as <br />to prevent accumulation and clogging. The equipment shall be constructed so that all <br />mixing and conveying parts up to and including the shaping die or gun, maintain the <br />material at the plastic temperature with heat transfer oil or electrical element-controlled <br />heat. Direct fire heat transfer will not be allowed. <br />E. The application equipment shall be so constructed as to insure continuous uniformity in <br />the dimensions of the stripe. The applicator shall provide a means for cleanly cutting off <br />square stripe ends and shall provide a method of applying "skip" lines. The use of pans, <br />aprons, or similar appliances which the die overruns will not be permitted. <br />F. Glass spheres applied to the surface of the completed stripe shall be applied by an <br />automatic bead dispenser attached to the striping machine in such a manner that the beads <br />are dispensed almost instantaneously upon the installed line. <br />G. Special kettle(s) shall be provided for melting and heating the thermoplastic material. The <br />kettle(s) shall be equipped with automatic thermostatic control devises to provide <br />uniform temperature control and prevent overheating of the material. The applicator and <br />kettle(s) shall be equipped and arranged to satisfy the requirements of the National <br />Fire Underwriters, the State of Florida, Miami-Dade County, and any municipal authority <br />applicable to where the work is being done.
