Analysis and Solutions to Common Construction Problems of Highway Hot Melt Marking Coatings

As an important component of road traffic safety facilities, the construction quality of highway markings directly affects the effectiveness of road use and driving safety. In the actual construction process, various technical difficulties are often encountered due to factors such as material characteristics, environmental conditions, and construction techniques. TOP ROAD Transportation Technology Co., Ltd., with years of technical accumulation and practical experience in the field of road marking, has conducted a systematic analysis of common problems in the construction of road marking coatings and summarized an effective solution.

The problem of insufficient adhesion of the marking line is manifested as local or large-scale detachment of the marking line after construction, especially after vehicle rolling, which is prone to peeling and stripping.

Reason analysis: TOP ROAD Transportation Technology Co., Ltd.’s technical team has found that adhesion issues mainly stem from the following aspects: incomplete grassroots treatment, presence of oil, dust, or moisture; Low ambient temperature affects the curing of coatings; Poor compatibility between paint and substrate; Excessive humidity during construction, etc. Especially at the transition between new and old asphalt pavements, adhesion problems are more likely to occur due to differences in pavement characteristics.

Solution: Firstly, it is necessary to ensure that the grassroots is clean and dry. TOP ROAD Transportation Technology Co., Ltd. recommends using professional cleaning equipment for thorough cleaning. For special substrates, the company’s specially developed reinforced primer can be used. During construction, environmental conditions should be strictly controlled to avoid working in rainy, snowy, or low-temperature environments. Choosing coating products that match the characteristics of the road surface is also crucial, and TOP ROAD Transportation Technology Co., Ltd. can provide customized solutions based on different road surface materials.

The problem of unsatisfactory reflective effect of the marking line is manifested as insufficient reflective brightness at night, uneven reflection, or rapid attenuation of reflective effect.

Reason analysis: TOP ROAD Transportation Technology Co., Ltd. has found through a large number of engineering cases that the problem of reflective effect mainly involves factors such as glass bead spreading process, coating transparency, and construction temperature control. Improper timing of glass bead spreading, uneven spreading amount, and inappropriate embedding depth can all affect the reflective effect. In addition, the transparency of the coating itself and the construction temperature also have a significant impact on its reflective performance.

Solution: Precise control of the glass bead spreading process is key. TOP ROAD Transportation Technology Co., Ltd. recommends using professional spreading equipment to ensure even spreading. During construction, the timing of spreading should be adjusted according to the ambient temperature to ensure that the glass beads are embedded in the coating in the optimal state. Choosing high-quality coatings with high transparency can significantly enhance the reflective effect. TOP ROAD Transportation Technology Co., Ltd.’s reflective coatings use a special formula that can maximize the reflective performance of glass beads.

The problem of insufficient durability of markings is manifested as the rapid wear and fading of markings after they are put into use, resulting in a much shorter service life than expected.

Reason analysis: TOP ROAD Transportation Technology Co., Ltd. has found that durability issues are closely related to material formulation, construction thickness, environmental factors, and other factors. Insufficient resin content, substandard filler quality, and uneven construction thickness in coatings can all affect durability. Especially in heavy traffic sections, higher requirements are placed on the wear resistance of materials.

Solution: Choosing high-quality marking coatings is the foundation. TOP ROAD Transportation Technology Co., Ltd.’s products use high-quality raw materials with excellent wear resistance and weather resistance. During construction, the thickness of the marking should be strictly controlled to ensure that it meets the design requirements. For special road sections, reinforced products can be selected. TOP ROAD Transportation Technology Co., Ltd. has specially developed high wear resistant marking coatings for heavy-duty traffic, which can significantly extend the service life.

The problem of blistering and cracking on the marking line is manifested by the appearance of bubbles, pinholes, or fine cracks on the surface of the marking line, which affects its appearance and performance.

Reason analysis: TOP ROAD Transportation Technology Co., Ltd.’s technical analysis shows that the problem of foaming and cracking is mostly related to factors such as moisture in the base layer, paint mixing, and temperature changes. The evaporation of moisture at the grassroots level, the introduction of air during coating mixing, and the shrinkage caused by drastic temperature changes can all lead to such problems.

Solution: Before construction, it is necessary to ensure that the base layer is completely dry. TOP ROAD Transportation Technology Co., Ltd. recommends conducting moisture content testing before construction. The mixing of paint should be moderate to avoid excessive mixing and the introduction of air. When applying in seasons with significant temperature changes, it is advisable to choose coating products with good elasticity. The flexible marking coating developed by the company can effectively adapt to temperature changes and reduce the risk of cracking.

The problem of uneven edge of the marking line is manifested as blurred boundary, burrs, sagging and other phenomena on the edge, which affect the aesthetics and recognition of the marking line.

Reason analysis: TOP ROAD Transportation Technology Co., Ltd. has found in engineering practice that edge quality issues are mainly related to construction equipment and operational processes. Factors such as wear of spray guns or scrapers, uneven construction speed, and wind interference can all lead to uneven edges.

Solution: Regularly inspect and maintain construction equipment. TOP ROAD Transportation Technology Co., Ltd. recommends using professional marking equipment and maintaining good working condition. During construction, a stable walking speed and equipment height should be maintained, and windproof measures should be taken in windy weather. For high demand markings, templates can be used for auxiliary construction to ensure neat and clear edges.

The problem of discoloration and yellowing of markings: White markings gradually turn yellow, while colored markings fade severely, affecting daytime visibility.

Reason analysis: TOP ROAD Transportation Technology Co., Ltd.’s research shows that the discoloration problem is mainly caused by factors such as insufficient material weather resistance, ultraviolet radiation, and environmental pollution. Some components in coatings are prone to chemical changes under the action of ultraviolet radiation, leading to color changes.

Solution: It is crucial to choose a marking coating with excellent weather resistance. TOP ROAD Transportation Technology Co., Ltd.’s coating products have added special UV resistant components to effectively prevent discoloration. During construction, suitable product grades can be selected based on local climate conditions, and it is recommended to use high weather resistant products in areas with strong ultraviolet radiation.

The problem of construction difficulties in special environments is manifested as the difficulty in ensuring the quality of markings during construction in special environments such as low temperature, high temperature, or humidity.

Reason analysis: TOP ROAD Transportation Technology Co., Ltd. has discovered through years of technical accumulation that construction problems in special environments are mainly related to material adaptability. Low temperature affects the fluidity and curing effect of coatings, while high temperature leads to rapid drying and high humidity affects adhesion.

Solution: TOP ROAD Transportation Technology Co., Ltd. has developed a series of all-weather marking coatings that can adapt to various harsh environments. Low temperature adaptability products can be used in low-temperature environments, slow drying formulas are selected in high-temperature seasons, and fast drying moisture-proof coatings are used in humid environments. The company also provides construction guidance for special environments to ensure ideal construction results under different conditions.
