"Road
Marking Tape ", also known as" pavement marking
Tape "or" self-adhesive marking tape "in jargon. This thing is being used more and more nowadays, especially for emergency repairs, temporary traffic organization, or small-scale repairs. It is much faster than hot melt marking lines, does not smoke, does not require equipment, but pays attention to the method. Only when used correctly can it be sturdy and durable.
The "
pavement marking tape" is like a large roll of strong "
Reflective Tape", with pressure-sensitive adhesive on the back and glass microbeads reflecting on the front. It is not permanent, but according to standard construction, it can be used for one to two years under moderate traffic volume without any problem.
Standard construction process and key points (follow to ensure quality):
Step 1: Preparation before Construction
1. Construction based on weather conditions: It is recommended that the ambient temperature and road surface temperature be above 10 ° C. Poor adhesion in cold weather, unable to stick firmly. Construction must not be carried out on rainy or damp roads.
2. Check activity: When receiving materials, check whether the specifications (width, color) and reflective brightness of the marking tape meet the requirements. Check the construction drawings, clarify the location and line type.
3. Preparation tools: Essential - laying tool (chalk or marking pen), tape measure, floor cleaning tool (hard broom, hair dryer, with wire brush if necessary), handheld compaction tool (special compaction roller or rubber hammer), paper cutter, cloth, handheld gas spray gun (optional, but strongly recommended).
4. Safety enclosure: Strictly follow the specifications of "Road Traffic Signs and Markings" to set up construction warning signs, cones, and road barriers, wear reflective clothing, and ensure the safety of the work area.
Step 2: Ground treatment (the most crucial step, determining whether to stick firmly or not)
1. Thoroughly clean: Use a hard broom to sweep away dust, mud, and debris from the construction area. Areas with oil stains should be cleaned with detergent or specialized cleaning agents, rinsed with clean water, and dried.
2. Deep cleaning: It is best to use a hair dryer or compressed air to blow out the fine dust in the gaps. The road surface must be dry, clean, and free of loose materials. This is the lifeline to ensure adhesion.
3. Old line treatment: If covering old markings, it is necessary to ensure that the edges of the old lines are flat and free from warping. It is recommended to partially treat severely damaged old wires first.
Step 3: Layout and Positioning
1. Accurate measurement: According to the design drawings, use a tape measure and chalk or marking pen to mark the reference line or positioning point on the road surface. The dotted line needs to calculate the interval accurately.
2. Pre laying: For long-distance or complex shapes (such as arrows and text), you can pre lay the marking tape according to its position without tearing off the backing paper, and see if it is suitable, especially at corners.
Step 4: Paste and compact (core operation)
1. Peel off the backing paper: Starting from one end, first peel off the backing paper that is about 30-50 centimeters long. Tip: You can fold the unfolded backing paper back to the back of the material for easy handheld use.
2. Align and paste: Align one end of the exposed adhesive surface with the ground reference line accurately and gently paste it on. After ensuring that the position is correct, use your hands to initially smooth it out.
3. Peel and paste at the same time: Slowly move backwards while peeling off the backing paper at a constant speed, and use your hand or towel to press the marking tape straight onto the road surface. Avoid generating bubbles and wrinkles. Two people working together is the best, one pulling and the other compacting.
4. Compaction exhaust:
-- After pasting, immediately use a dedicated compaction roller (or a drum wrapped in rubber) to repeatedly and forcefully roll from the middle to both sides, exhaust the air, and ensure that the rubber is completely adhered to the road surface.
-- Without rollers, you can use a rubber hammer or wooden block to cushion and strike, especially at the edges and seams, which must be firmly pressed.
-- Important Tip (Improving Durability Core): When conditions permit, before or after compaction, use a handheld gas spray gun flame (using weak fire, maintaining distance, quickly and evenly sweeping) to lightly and uniformly heat the surface of the marking strip. This can activate the adhesive, significantly increase the initial bonding force, and make it better adapt to the road surface texture. Be careful not to burn or deform the material.
5. Handling seams: When splicing is required, butt joint should be used, and the overlap should not exceed 3 millimeters. The joint must be tightly compacted.
Step 5: Post processing and inspection
1. Trimming: When encountering manhole covers or irregular edges, use a sharp paper cutter to cut neatly along the edges.
2. Clean the surface: After pasting, wipe the surface clean with a dry cloth to remove fingerprints and stains.
3. Open transportation: In theory, the road can be opened to traffic after being glued and compacted. However, during high temperatures in summer, it is recommended to wait for 15-30 minutes after compaction to further stabilize the adhesive properties. Once heated with a spray gun and cooled, it can be opened.
4. Inspection: Check for curled edges, bubbles, and wrinkles. Minor issues can be re compacted with a roller or locally heated for compaction. Major issues require lifting and re pasting.
