Summary of Specifications:
All existing pavement markings shall be removed from the pavement to the maximum extent possible, by methods that do not materially alter or damage the surface or texture of the pavement, to the satisfaction of the City Traffic Engineer or designee. The proposed method of pavement marking removal shall be designated by the Contractor at the preconstruction conference, and approved by the City Traffic Engineer or designee. Operations that do not produce the desired result, damage the pavement, or may constitute a hazard to the traveling public will not be permitted. Materials deposited on the pavement as a result of removal of pavement markings shall be promptly removed so as not to interfere with traffic or roadway drainage and disposed of properly.
The pavement surface area to be covered with pavement marking material shall be sandblasted, or blast cleaned by another approved method, prior to the application of pavement primer or prior to the placing of pavement marking material when used without a pavement primer. A dustless-abrasive shot blasting, power washing, or other approved cleaning method may be used to do the sandblasting work. The sandblast shall be applied to remove all dirt, laitance, and curing compound residue. After sandblasting, all loose dust and dirt shall be removed before application of pavement primer or pavement marking material. The surface of the pavement shall be clean, free of loose foreign material, dry; no moisture for a minimum of 48 hours prior to application of the markings and the air temperature shall be at least 60 °F.
This preformed plastic pavement marking shall be suitable for application on asphalt or concrete pavement. The strip shall be applied at the locations called for on the plans or as directed. If recommended by the manufacturer, an epoxy resin primer shall be applied to all pavement surfaces prior to the application of the preformed plastic pavement marking.
