Application Case of Hot Melt Coating for Marking Lines in Highways

As the main artery of every country’s transportation network, highways place extremely high demands on the durability, reflectivity, and safety of marking materials. TOP ROAD Transportation Technology Co., Ltd.’s hot melt marking coating has achieved significant application results in multiple highway projects across the country due to its excellent performance.

1、 Application Practice of Mountainous Highways
TOP ROAD hot melt coatings demonstrate excellent environmental adaptability in mountainous highway projects that traverse complex terrains. For special working conditions such as continuous bends and steep slopes, the company has optimized the coating ratio to enhance the reflective durability of the markings in humid and foggy environments. The project acceptance shows that the markings remain clear and visible even in rainy and foggy weather, effectively improving the safety factor of driving.

2、 Innovative application of marking in renovation and expansion projects
In a highway renovation and expansion project, the TOP ROAD team innovatively adopted a segmented construction plan. By precisely controlling the melting temperature of materials and the construction timing, we ensure a good connection between the new and old markings. Of particular note is the elastic reinforcement formula used at the bridge joints, which effectively overcomes the problem of marking cracking caused by foundation deformation and demonstrates excellent displacement resistance performance.

3、 Breakthrough in Low Temperature Environment Construction Technology
A highway project in northern China is facing winter construction challenges, and TOP ROAD’s low-temperature adaptive formula has successfully overcome technical bottlenecks. By adding special additives and improving the construction process, the coating maintains good fluidity and adhesion under low temperature conditions. Project practice has proven that the formula markings maintain stable reflective performance even in icy and snowy climates.

4、 Long tunnel marking safety enhancement plan
In the lighting environment of the extra long tunnel, TOP ROAD adopts high reflective series coatings, and optimizes the glass bead particle size ratio to produce uniform diffuse reflection of the markings under artificial lighting conditions. This solution effectively alleviates driver visual fatigue, and the related technology has obtained industry specific certification.

5、 Visualization Enhancement Project for Interchange
TOP ROAD innovatively utilizes color management solutions to address the complex traffic flow of large interchanges. By adopting a color system that complies with international standards, significant color differences are formed between guiding lines in different directions, helping drivers quickly identify routes while driving at high speeds. This case has become a benchmark project in the industry.

6、 Case study on adaptability of special pavement structure
The TOP ROAD technical team successfully solved the compatibility problem between special asphalt substrates and marking coatings through on-site testing on road sections using new paving materials. The customized interface treatment agent ensures the long-lasting adhesion of the marking on various new pavement materials, providing valuable experience for the industry.

7、 Application of Intelligent Construction Technology
In a certain smart highway project, TOP ROAD cooperates with an intelligent layout robot system to achieve digital management of marking construction. Real time monitoring of construction parameters through IoT technology ensures that each section of the marking meets the design standards, creating a new intelligent construction model for marking.

These successful cases demonstrate that TOP ROAD hot melt coatings can not only meet the conventional needs of highways, but also provide customized solutions for special working conditions. The full process technical service system established by the company provides professional support for each project, from preliminary survey to later maintenance.

Through practical application in numerous highway projects in various countries around the world, TOP ROAD Transportation Technology Co., Ltd. continues to accumulate valuable experience and promote the advancement of hot-melt marking technology. We look forward to collaborating with more projects to jointly enhance the safety level of highways in countries around the world.
