Detailed Process of Hot-Melt Road Marking Paint Application: From Material Preparation to Road Opening

Road marking construction is an important part of ensuring road traffic safety, and hot-melt marking coatings have become a widely used material choice due to their excellent durability and reflective properties. TOP ROAD Transportation Technology Co., Ltd., with years of industry experience, provides you with a detailed analysis of the entire process technology of hot melt coating construction, helping the construction team master the technical points of each link.

Thorough preparation work before construction

Material inspection and pre-treatment are the foundation for ensuring construction quality. TOP ROAD Transportation Technology Co., Ltd. suggests that strict inspection of hot melt coatings should be carried out before construction to ensure that the materials are free from moisture, clumping, and other phenomena. At the same time, it is necessary to prepare corresponding supporting materials such as primer and glass beads, and check the integrity of the construction equipment. Materials should be stored in a dry and ventilated place, away from direct sunlight.

On site investigation and plan formulation are key to ensuring the smooth progress of construction. The construction team needs to conduct a detailed survey of the working road surface in advance to understand the material, smoothness, cleanliness, and other conditions of the road surface. The technical team of TOP ROAD Transportation Technology Co., Ltd. emphasizes the need to develop corresponding construction plans based on different road conditions, including specific parameters such as the selection of sub coating agents and construction temperature control.

Baseline marking and road surface treatment

Accurate layout is a prerequisite for neat and beautiful markings. Construction personnel need to conduct precise measurement and layout according to the design drawings, and use professional equipment to draw reference lines. TOP ROAD Transportation Technology Co., Ltd. suggests using precision instruments such as total stations for layout to ensure accurate and error free marking positions. For curved road sections, it is necessary to increase the density of reference points appropriately to ensure smooth alignment.

Road surface cleaning directly affects the adhesion of markings. Before construction, it is necessary to thoroughly remove impurities such as dust, oil stains, and moisture from the road surface. TOP ROAD Transportation Technology Co., Ltd. recommends using high-pressure cleaning equipment in conjunction with mechanical cleaning to ensure that the road surface meets the cleanliness requirements for construction. For areas with severe oil pollution, specialized cleaning agents need to be used for treatment.

Key technologies for coating agent construction

The application of primer is an important step in enhancing adhesion. TOP ROAD Transportation Technology Co., Ltd. recommends using a specialized coating machine for construction to ensure that the lower coating agent is evenly applied and the thickness is appropriate. During construction, attention should be paid to the influence of environmental temperature, and work should be avoided when the humidity is too high or the temperature is too low. After coating, it is necessary to wait for sufficient time for the primer to dry completely.

The key points of quality control need to be closely monitored throughout the process. Construction personnel should check the coating effect of the coating agent at any time, and promptly repair any omissions or uneven thickness found. TOP ROAD Transportation Technology Co., Ltd. reminds that the drying time of the coating agent should be flexibly adjusted according to environmental conditions to ensure complete drying before proceeding to the next step of construction.

Hot melt coating melting and insulation

Temperature control is the core of ensuring construction quality. Hot melt coatings need to be heated to a suitable temperature in a dedicated melting kettle and maintained at a constant temperature. TOP ROAD Transportation Technology Co., Ltd. emphasizes that high temperatures can cause the decomposition of coating components, while low temperatures can affect leveling, and must be strictly controlled within the temperature range required by the material.

Material mixing and insulation require professional operation. During the melting process, the coating should be continuously stirred to prevent precipitation and local overheating. TOP ROAD Transportation Technology Co., Ltd. recommends using construction equipment with insulation function to ensure temperature stability of the coating during the construction process. At the same time, moisture-proof measures should be taken to avoid rainwater affecting material properties.

Marking and glass bead spreading

Mechanized construction ensures uniform and consistent quality of markings. When using a professional marking vehicle for marking, it is necessary to control the driving speed and discharge volume to ensure that the thickness of the marking meets the design requirements. TOP ROAD Transportation Technology Co., Ltd. suggests conducting a trial drawing and adjusting the equipment parameters before proceeding with formal construction.

Synchronously spreading glass beads enhances nighttime reflective effect. It is necessary to spread glass beads in a timely and uniform manner before the coating is cured to ensure that the reflective effect meets the standard. TOP ROAD Transportation Technology Co., Ltd. reminds that the timing of spreading should be adjusted according to the ambient temperature to avoid the glass beads being embedded too deeply or too shallowly, which may affect the reflective performance.

Post construction maintenance and quality inspection

Adequate curing and maintenance are key to ensuring the service life. After the marking is completed, warning signs need to be set up to prevent vehicles or pedestrians from rolling over the marking line too early. TOP ROAD Transportation Technology Co., Ltd. suggests that sufficient curing time should be allowed according to environmental conditions to ensure that the markings are fully cured before opening to traffic.

Comprehensive quality inspection ensures that the construction effect meets the standard. Use specialized testing instruments to check the thickness, reflectivity, and other indicators of the markings, and promptly repair any problems found. TOP ROAD Transportation Technology Co., Ltd. has established a comprehensive quality traceability system to provide professional technical support and service guarantees for each project.

By strictly following the construction process requirements, hot-melt marking can achieve better results in use.
