Road markings are an important part of traffic management. Their clarity, durability, and reflective performance directly affect road traffic safety and traffic efficiency. With the continuous growth of traffic volume and the improvement of people's requirements for road safety, traditional road marking paint construction techniques have been difficult to meet the increasing demands. Therefore, improving the construction techniques of road marking paint and enhancing the quality and service life of road markings have become important issues in the current field of traffic engineering.I. Shortcomings of Traditional Construction TechniquesTraditional road marking paint construction techniques mainly use hot-melt paints and solvent-based paints, with construction methods mostly being manual brushing or mechanical spraying. These traditional techniques have the following shortcomings:Low construction efficiency**: Manual brushing is inefficient and cannot meet the needs of large-scale ...

The preparatory work before the construction of road marking paint is a key link to ensure the smooth progress of the construction and the quality of the markings. The following are the preparations that need to be done before construction, covering aspects such as the environment, materials, equipment, personnel, and safety.1. Preparation of Construction Environment1.1 Road Condition InspectionBefore construction, a comprehensive inspection of the construction section must be carried out to ensure that the road surface is flat, free of debris, stagnant water, oil stains, etc. If there are cracks, potholes, or other defects on the road surface, they must be repaired in advance to ensure the adhesion and durability of the markings.1.2 Weather ConditionsMarking construction has high requirements for weather conditions, and it usually needs to be carried out in dry weather without rain, fog, or strong winds. The temperature is generally required to be above 5°C, and the humidity should...

After the construction of road marking paint, sanding is a common problem, especially in areas with heavy traffic flow and harsh climatic conditions. Sanding not only affects the appearance and service life of the markings but also may pose hidden dangers to traffic safety. Therefore, it is crucial to take effective measures to prevent sanding. The following discusses in detail how to prevent sanding of road marking paint from aspects such as material selection, construction technology, and post-maintenance.I. Material SelectionHigh-quality coatings Choosing high-quality marking paint is the basis for preventing sanding. High-quality coatings have better adhesion, wear resistance, and weather resistance, and can effectively resist the impact of external factors such as vehicle rolling and climate changes. Common marking paints include hot-melt, solvent-based, and water-based paints. Among them, hot-melt paint is widely used due to its excellent wear resistance and durability.Filler se...
