1. Make preparations before construction and clarify the responsibilities of construction personnel. There must be a hot melt coating taped construction record, which accurately records the road surface and air humidity, temperature, weather conditions, wind direction, road surface conditions, paint melting temperature, hot melt coating usage, and construction coating rate. The hot melt coating in the hot melt kettle must be stirred evenly, and the materials in the hot melt kettle must be homogenized before being discharged. Different colors and hot melt coatings of different manufacturers should not be mixed to avoid discoloration of the paint or other undesirable consequences after the construction is put into use. When changing to another color or another brand of paint, the hot melt kettle should be cleaned.

2. Check the construction effect of the hot melt deceleration band at any time, as follows whether the amount of hot melt coating is appropriate, too little adhesion is not enough, too much will dissolve the substrate (asphalt pavement); hot melt deceleration band marking during construction Whether the material temperature in the hopper of the line car is within the standard range; whether the thickness of the marking meets the requirements; whether the glass beads on the marking surface are evenly spread and whether the amount is sufficient; whether the appearance and adhesion of the marking and the size of the marking meet the requirements.

3. The road surface marked by hot melt coating needs to be clean and dry. During construction, remove the mud and stones on the road surface. At the same time, pay attention to the road surface after it is completely dry in rainy day before construction. The falling off of the marking line is a gradual process, usually starting from a small point. Once the marking line falls off, it will intensify over time and become a cannibalization. The unremoved dirt or dust is usually the easiest The points that fall off are also prone to fall off, so the soil, stones, etc. on the part to be marked should be removed during hot melt coating construction.

To sum up, hot melt coating must be cleaned, staked, repaired, safety measures and other procedures must be carried out in hot melt coating construction. In order to obtain satisfactory quality, attention must be paid to the cooperation of all links. Hot melt coating marking is a part of road construction and is inseparable from actual traffic safety.
