Effects of High Temperatures in Summer on Road Markings

Since the beginning of summer, the temperature has continued to rise around the world. Just in China, the surface temperature of asphalt roads in some areas can even reach over 70°C. Today we would like to discuss the impact of high temperature weather on road markings and how to solve these issues.

Functional impact:

1. Softening and deformation
Hot weather can cause road markings to soften, especially when using certain types of hot-melt road marking paint. Softened road markings may become sticky or deformed, affecting their function and appearance.

2. Reduced anti-skid value of road markings
As the paint softens, its surface may become smoother, which will reduce the friction between the vehicle tires and the road markings, thereby reducing grip and increasing safety hazards.

3. Reduced visibility
After the road markings soften, the reflective glass beads may fall off or be pressed into the inside of the road markings. At night or in low light conditions, the visibility of the road markings will decrease significantly, and the reduction in reflective performance will directly affect traffic safety.

4. Increased pollution of road markings
After the paint softens, the surface of the road markings is more susceptible to dirt in the environment. When the ambient temperature drops, the dirt will adhere to the surface of the road markings, reducing the overall image of the city.

Solutions：

1. Choose high temperature stable materials
Choose normal temperature reactive road marking paint, which is not affected by temperature changes; or choose paint with better high temperature stability, such as resin with high softening point.

2. Add UV stabilizers and antioxidants
Adding UV stabilizers and antioxidants to the paint can reduce the negative effects of high temperature and sunlight on the paint.

3. Regular maintenance and inspection
Regularly inspect and maintain road markings, and repair damaged parts in time to ensure their performance and all-weather visibility.

In Conclusion, high temperatures in summer will make hot melt markings soft and sticky, affecting their thickness, visibility, wear resistance and anti-skid functions, while the impact on reactive two-component markings is much smaller. In high temperature areas in summer, two-component paint or hot melt paint with better thermal stability and continuous maintenance measures can be used for management to ensure the safety and functionality of the road.

The ultimate purpose of installing and maintaining road markings is to improve road safety; for this, high-quality raw traffic safety materials are essential.
