The Contractor shall undertake all work between the dates of July 1, 2024 and August 31, 2024 inclusive.
Traffic Control for all linear markings on public streets and highways shall consist of an escort vehicle with a rotating amber beacon stationed to the rear of the line painting equipment. The stationing distance shall be commensurate with the speed limit in force on the respective street or highway. Where necessary, the Contractor shall supply flag persons or barricades to protect Workers and the Work.
Paint Products may be either water based or organic solvent based Traffic Paint. Paint Products to be used shall conform to the Regular White Paint and Regular Yellow Paint formulations on the Alberta Transportation Products List.
Prior to the start-up and at any time during the Work, the Contractor shall provide samples of all paint materials to be used. The County may arrange for testing of the paint samples.
Glass Beads shall conform to AASHTO M247 Type 1 or Type 2.
The County will undertake sweeping of all Hamlet roadways on the day prior to anticipated line painting operations. In addition to this, it will be the Contactor’s responsibility to ensure that all surfaces to be painted are free of debris, dust, particulates and oils and are perfectly clean and dry.
The paint and beads shall be applied at the following rates:
- Paint: 15-17 mils wet (38 to 42 litres/KM of 10cm line)
- Glass Beads: 0.6 to 0.7 kg per litre of paint
Paint lines shall be applied to precisely cover existing markings. Where this cannot be achieved, old markings shall be obliterated. All road marking equipment shall be equipped with laser or video guidance systems to enable the paint to be applied with clean, sharp edges and in accordance with application rates and thickness specified.
The temperature of the paint on application shall be between 40°C and 70°C unless otherwise indicated in the Manufacturer’s specifications.
All markings shall have sharp, defined edges, and shall be free of wobbles and irregularities. Spraying shall be done to avoid bleeding and overspray.
Paint markings shall be protected by cones that remain in place until the paint is sufficiently dry to prevent spreading and tracking.
