How do you install pavement marking tape?

The installation of pre formed pavement marking tape needs to follow standardized construction procedures and precautions to ensure the adhesive strength, durability, and reflective performance of the marking tape. The following are detailed installation steps and key points based on search results:

Preparation before construction
Material and equipment inspection
◉ Ensure that the surface of the marking tape is free from damage, deformation, or aging.
◉ Prepare tools such as primer, adhesive, expansion bolts (if auxiliary fixation is required), pressure rollers, rubber hammers, brooms, hair dryers, etc.
◉ Testing environmental conditions: air temperature ≥ 5 ℃, ground temperature ≥ 10 ℃, avoid rainy days or insufficiently dry road surfaces (dry for more than 24 hours after rain).
Base treatment
◉ Cleaning the road surface: Thoroughly remove dust, oil stains, and debris, and if necessary, use a wire brush to treat floating objects or loose particles.
◉ Polishing and filling: Polish or fill uneven road surfaces to ensure that the base smoothness meets the requirements.
◉ Measurement and laying out: According to the design drawings, mark the marking position with chalk or bullet lines, and control the error within the standard range.

Primer application and marking tape laying
Primer construction
◉ Mixing primer: Mix according to the product instructions to ensure uniformity.
◉ Brushing method: Use a spray gun or roller brush to evenly brush the marked area, 1-2cm beyond the contour line, with a thickness controlled at 0.1-0.2mm. Wait for the primer to dry until it is not sticky to the hands (usually 10-15 minutes).

Laying of marking tape
◉ Cutting marking tape: Cut the marking tape according to the layout size, and the edges should be neat and free of burrs.
◉ Paste operation: Tear off the isolation paper on the back of the marking tape, align and paste along the contour line, gradually advance from one end, and avoid the generation of bubbles.
◉ Pressure treatment:
   ● Use a pressure roller or rubber hammer to repeatedly roll the marking tape, especially at the corners, to ensure complete adhesion   with the road surface.
   ● If bubbles appear, a sharp tool can be used to puncture the exhaust and re compact it.

Auxiliary fixation and special treatment
Fixed method
◉ Adhesive fixation: Suitable for conventional road surfaces, use high-strength adhesives (such as polyurethane pressure-sensitive adhesives) to ensure adhesion.
◉ Mechanical fixation: During the construction of bends, high traffic areas, or long marking strips, expansion bolts or rivets can be used to assist in fixation and enhance the anti stripping force.

Special scenario response
◉ Asphalt pavement: Newly laid asphalt needs to be opened to traffic for 10 days before construction to ensure that floating dust is completely removed.
◉ Cement pavement: New cement pavement needs to be open to traffic for more than 20 days, and construction can only be carried out after the surface slurry is removed.

Post construction inspection and maintenance
Quality acceptance
◉ Check the flatness, reflective performance, and adhesive strength of the marking tape, and use tools such as a reverse reflection coefficient measuring instrument to test.
◉ The edge of the marking strip and the road surface are not raised, and the gap width is ≤ 1mm.
Maintenance and opening time
◉ Avoid sudden braking or heavy load crushing of vehicles within 24 hours after construction to ensure complete curing of the adhesive.
◉ Clean up the residues on the construction site, record the construction date, material batch and other information for future reference.
