628.01 Description. This work consists of furnishing materials and installing cold plastic
pavement markings of the type specified in r easonably close conformi ty 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 projec t. 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 th e 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.
628.04 Method of Measurement. Cold plastic pavement markings will be measured for
payment in accordance w ith Subsection 626.04.
628.05 Basis of Payment. Cold plastic pavement markings will be paid for at the contract
unit price per mile, linear foot or square foot, as applicable, which shall be full compensation for co mpleting the work. Payment will be made under: 628-A: 6” Cold Plastic Traffic Stripe, Skip White - per linear foot or mile 628-B: 6” Cold Plastic Traffic Stripe, Continuous White - per linear foot or mile 628-C: 6” Cold Plastic Traffic Stripe, Skip Yellow - per linear foot or mile 628-D: 6” Cold Plastic Traffic Stripe, Continuous Yellow - per linear foot or mile 628-E: Cold Plastic Detail Stripe, Color - per linear foot 628-F: Cold Plastic Legend, White - per square foot or linear foot 628-G: 6” High Performance Cold Plastic Traffic Stripe, Skip White - per linear foot or mile 628-H: 6” High Performance Cold Plastic Traffic Stripe, Continuous White - per linear foot or mile 628-I: 6” High Performance Cold Plastic Traffic Stripe, Skip Yellow - per linear foot or mile 628-J: 6” High Performance Cold Plastic Traffic Stripe, Continuous Yellow - per linear foot or mile 628-K: High Performance Cold Plastic Detail Stripe, Color - per linear foot 628-L: High Performance Cold Plastic Legend, White - per square foot or linear foot SECTION 629 - VEHICULA R IMPACT ATTENUATORS
629.01 Description . This work consists of furnishing all materials, components and
accessories and installing impact attenuator systems meeting all of the requirements specified on the plans or in the contract documents, and assembled and constructed at the location(s) indicated on the plans or as established by the Engineer. This work shall also include the installation of median barrier end sections in accordance with the plans, specifications, and the manufacturer's recommendations.
629.02 Materials . Materials used in the construction of the vehicular impact attenuator
system shall all be new and shall conform to the applicable requirements of the respective section(s) of Section 700, as may be supplemented by requirements in other contract documents for the particular system installation. Approved impact attenuator systems shall meet standardized testing defined in NCHRP Report 350 or MASH. In addition, documentation from FHWA must accompany the devices, indicating that the devices meet the ap propriate crash test criteria and can be used on the National Highway System (NHS). Prior to installation, the Contractor shall provide two copies of the manufacturer’s installation de tails to the Project Engineer. The Project
