CITY OF LAKE ELMO, MN | PROJECT NO. 2024.108 PAVEMENT MARKINGS 3217-2 A. Glass Beads. Glass beads shall be installed in accordance with MnDOT Spec 2582. B. Tolerances. A tolerance of ¼-inch under or ¼-inch over the specified width will be allowed for striping provided the variation is gradual and does not detract from the general appearance. Broken line segments may vary up to ½-foot from the specified lengths provided the over and under variations are reasonably compensatory. Alignment deviations from the specified lane widths shall not exceed 1-inch. Establishment of application tolerances shall not relieve the Contractor of their responsibility to comply closely with the planned dimensions. 4. PROTECTION OF PAVEMENT MARKINGS: The Contractor shall furnish and install all necessary warning and directional signs and devices in order to maintain traffic while pavement markings are being applied in the presence of traffic, and to protect uncured markings as needed until traffic can cross markings without damaging markings. When necessary, a pilot car and flaggers shall be used to provide adequate control and direction of traffic. Warning signs and barricades shall be placed only where marking operations are in progress, shall be relocated as often as necessary, and shall not be left in place over night. Unless approved by the Engineer, traffic shall be allowed to keep moving at all times and the striping equipment shall be operated in a manner that will not make it necessary for traffic to cross uncured markings. 5. CLEANING: Waste materials shall be removed or destroyed at the end of each work day. Upon completion of the Work, all containers and debris shall be removed from the site. Epoxy spots upon adjacent surfaces shall be carefully removed by approved procedures which will not damage the surfaces and the entire job shall be left clean and acceptable to the City. 6. CERTIFICATION: The Contractor shall furnish a certified report on the quality of materials shipped to the Project. This report shall not be interpreted as a basis for final acceptance. When required, all emptied containers shall be returned to the epoxy material storage area or made available for checking by the Engineer. The Contractor shall make accurate accounting of the epoxy materials used in the Work. 7. CORRECTION OF DEFECTS: All pavement markings not conforming to the requirements of the Contract shall be removed and replaced or otherwise repaired to the satisfaction of the Engineer. Removal of unacceptable work shall be accomplished with suitable blasting or grinding equipment unless other means are authorized by the Engineer. If the Engineer requires removal and replacement, the Contractor shall remove, by an approved process, at least 90% of the deficient line, with no excessive scarring of the existing pavement. The removal width shall be one inch wider all around the nominal width of the pavement marking to be removed. END OF SECTION
