Detailed Process of Hot Melt Line Construction
1. Road Cleaning
Before operation, the nearby area must be cleaned to ensure that
there are no impurities such as oil, water, fallen leaves, weeds,
etc., so as not to affect the adhesion effect, flatness and
reflection effect of the line.
2. Set the point and mark line
In the process of sampling, the calculation and measurement must be
carried out in strict accordance with the construction drawings.
Measure the several lanes that need to be drawn on the road, set
the point, and then mark it with a stone pen. Use titanium dioxide
powder to glue the rope for the elastic line. After the rope is
removed, it will be corrected and improved to ensure that the line
shape is clear and accurate.
3. Apply the Primer
The lower coating is a common binder in hot melt marking
construction. It is applied to the highway road surface, which can
make the hot melt coating better adhere to the road surface.
4. Spray the paint
Before construction, first check the relevant coating equipment.
Then heat the paint.
When the trolley moves forward, the paint will form a coating film
on the road, and a layer of glass beads should be sprinkled on the
coating film during the coating process.
When the trolley moves forward, take the reference line as the
ruler, control the thickness and width of the line, and ensure the
coordination, clarity and smoothness of the line connection between
the straight line and the curve.
Note: During the coating process, in order to avoid the
sedimentation and separation of the paint, it is necessary to stir
the paint frequently.
5. Check and correct
After the coating is completed, check and correct the line shape,
check the spread of glass beads, etc. After confirming that it is
correct, the construction site will be cleaned up.
After the line is dried and hardened, the relevant construction equipment can be
transferred, the safety facilities can be dismantled, and the
traffic can be opened.
