The Applicability and Construction Key Points of Road Marking Hot-Melt Paint Under Different Pavement Conditions – Let Me Tell You

In road marking construction, hot melt coatings have become the preferred material for engineering and construction teams due to their durability, reflective effect, and wide applicability. However, different road conditions have a direct impact on the construction quality and long-term performance of coatings. As a professional team of TOP ROAD Transportation Technology Co., Ltd., we rely on years of experience to deeply analyze the applicability and key construction points of hot melt coatings on various road surfaces, helping engineering personnel improve construction efficiency and marking quality.

1、 Characteristics and Applicable Scenarios of Hot Melt Coatings

Hot melt coating is applied by heating and melting, and after curing, it forms wear-resistant, reflective, and strongly adhesive markings. Its advantage lies in its strong adaptability, which can be used for various foundations such as asphalt pavement, concrete pavement, new and old pavement, etc. For example, on asphalt pavement, hot melt coatings can effectively penetrate and bond, ensuring long-term stability of the markings; On concrete pavement, it is necessary to use a special primer to enhance the bonding strength. TOP ROAD Transportation Technology Co., Ltd. provides hot-melt coating products that are optimized for different road surface characteristics to ensure excellent performance in different environments.

2、 Key points for construction under different road conditions

Newly paved asphalt pavement: The new pavement is prone to leakage of asphalt oil, which may cause yellowing or pollution of the markings. Before construction, it is necessary to ensure that the road surface is fully cured. It is recommended to wait for a period of time after the road is open to traffic before starting the road, or to check the stability of the road surface through watering tests. TOP ROAD’s hot melt coating uses high-purity resin, which can reduce oil pollution interference and ensure the whiteness of the markings.

Old or damaged road surface: Cracks or loose areas on the road surface are prone to bubble formation or detachment. Before construction, it is necessary to thoroughly clean and fill the gaps, and adjust the temperature of the coating – too high a temperature will exacerbate bubbles, and too low a temperature will affect leveling. Our team suggests determining the optimal parameters through on-site testing.

Cement concrete pavement: This type of pavement has strong hydrophilicity and weak adhesion with coatings. Special primer must be applied and wait for it to completely dry before applying. TOP ROAD’s primer products can effectively enhance adhesion and prevent later detachment.

Special scenarios (such as tunnels and bridges): When space is limited or the base is smooth, it is necessary to use coating models with stronger adhesion and strictly control the humidity and temperature of the construction environment.

3、 Common Problems and Solutions

Yellow markings: Often due to overheating of the coating or road pollution, it is necessary to optimize the boiling temperature and construction rhythm.

Insufficient retroreflection value: related to the amount of glass bead spreading and coating thickness, standard process should be followed.

Poor durability: often due to unclean road surfaces or incomplete melting of coatings, quality monitoring needs to be strengthened during construction. TOP ROAD Transportation Technology Co., Ltd. provides full process technical support, from material selection to on-site guidance, to ensure the long-term service of marking lines.

The successful application of hot melt coatings relies on accurate judgment of road conditions and standardized construction.
