What preparations are needed before the construction of road marking paint?

The preparatory work before the construction of road marking paint is a key link to ensure the smooth progress of the construction and the quality of the markings. The following are the preparations that need to be done before construction, covering aspects such as the environment, materials, equipment, personnel, and safety.

1. Preparation of Construction Environment

1.1 Road Condition Inspection

Before construction, a comprehensive inspection of the construction section must be carried out to ensure that the road surface is flat, free of debris, stagnant water, oil stains, etc. If there are cracks, potholes, or other defects on the road surface, they must be repaired in advance to ensure the adhesion and durability of the markings.

1.2 Weather Conditions

Marking construction has high requirements for weather conditions, and it usually needs to be carried out in dry weather without rain, fog, or strong winds. The temperature is generally required to be above 5°C, and the humidity should not be too high. Attention should be paid to the weather forecast before construction to avoid construction in severe weather conditions.

1.3 Traffic Management

Before construction, it is necessary to coordinate with relevant departments to formulate a traffic management plan to ensure the safety of the construction area and traffic order. It is usually necessary to set up temporary traffic signs, cones, warning lights, etc., and arrange special personnel to direct traffic when necessary.

2. Material Preparation

2.1 Coating Selection

Select appropriate marking paints according to construction requirements. Common types include hot-melt, cold-applied, and two-component paints. Hot-melt paints are suitable for high-grade highways, cold-applied paints for general roads, and two-component paints for special environments. The paints shall comply with national or industry standards and be accompanied by certificates of conformity and test reports.

2.2 Paint Storage

Paints should be stored in a dry, cool, and well-ventilated place, away from direct sunlight and high temperatures. Hot-melt paints need to be preheated before construction to ensure they reach the construction temperature (usually 180℃-220℃).

2.3 Auxiliary Materials

Prepare necessary auxiliary materials, such as glass beads (used to improve nighttime reflective effect), primers (used to enhance adhesion), thinners (used to adjust paint viscosity), etc.
