628Cold Plastic Pavement Markings

628.01 Description. This work consists of furnishing materials and installing cold plastic

pavement markings of the type specified in reasonably close conformity with the plans and these specifications. Cold plastic traffic markings may be used in lieu of hot applied thermoplastic markings. Substitution will only be allowed for pay items 626-A through H. Substituted cold plastic markings shall be of the same color and width as that required for the hot applied stripe. Unless otherwise specified, the markings, whether hot applied or cold plastic, shall be of the same type of material for the entire project. Material and construction requirements for substituted cold plastic traffic markings shall meet the requirements of this section of the Standard Specifications. The layout and spacing for substituted cold plastic traffic markings will remain as shown in the plans, or in the contract documents, for hot applied thermoplastic markings. Measurement of substituted cold plastic traffic markings shall be made in accordance with this subsection of the Standard Specifications. Payment for substituted cold plastic traffic markings shall be made at the unit price bid for the appropriate hot applied thermoplastic marking.

628.02 Materials. Cold plastic marking material shall meet the requirements of

Subsection 720.04. High performance cold plastic marking material shall meet the requirements of Subsection 720.07.

628.03 Construction Requirements.

628.03.1 Equipment. The material manufacturer sha ll furnish a mechanical applicator

for the application of 16-inch wide film. When high performance profile cold plastic pavement markings are used, the manufacturer shall provide application equipment, manual or automatic as necessa ry for the job requirements. These applicators shall be capable of applying markings to the required alignment and dimensions shown on the plans or in the contract documents. The mechanical applicator shall be provided on location at the time designated and for the duration of the application period. The material manufacturer shall provide technical assist ance for operation and maintenance of the mechanical applicator at the discretion of the Engineer.

628.03.2 General. The free-air temperature shall be at least 60°F. The pavement surface

shall be dry and clean. All dirt, loose particles of pavement, and other foreign material shall be removed prior to application of the pavement marking material. All longitudinal stripes shall be mechanically applied. Detail stripe and legend may be applied manually. Only butt splices wit hout overlay will be permitted fo r multiple piece and line type markings. Except for legend, the specified width of the markings shall be made in a single tape application. Where possible the markings shall be placed adjacent to rather than on longitudinal construction joints in the pavement. Placement tolerance will be as set out in Subsection 625.03.3. Markings not meeting these tolerances shall be removed and replaced at the Contractor's expense.

628.03.3 Application. Both mechanical and manual application shall be in accordance

with the manufacturer's instructions. A liquid contact shall be used at the rate recommended by the manufacturer for detail stripe and legend symbols. Liquid contact cement shall not be used elsewhere unless specified by the manufacturer. When liquid contact cement is used, the newly placed marki ngs shall be protected from traffic for the period of time recommended by the manufacturer of the cement.
