How to effectively and thoroughly remove old road markings has become the primary issue in road marking maintenance. Problem Analysis: Since no new markings will be painted in the original locations after the old markings are removed, a complete removal of the old markings is necessary.

As an important municipal traffic auxiliary facility, road markings serve functions such as lane division, guiding traffic flow, and creating traffic channelization. Road markings are mainly applied to the road surface layer and are subject to long-term exposure to sun, rain, and the impact and wear of vehicles. When the road surface needs to be re-divided, the old road markings must be removed. If the old road markings are not completely removed, or if the road surface is damaged and large areas of asphalt peel off after removal, it undoubtedly increases the future maintenance costs of the markings. Therefore, how to effectively and thoroughly remove old road markings has become the primary issue in road marking maintenance.

Problem Analysis: Since no new markings will be painted in the original locations after the old markings are removed, a thorough removal of the old markings is necessary. The main objective of this work is to completely remove the existing road markings to avoid confusion with subsequent new markings.

1. Environmental Analysis: The following main problems were identified: Inconsistent skill levels and insufficient training among construction personnel; insufficient grinding power from equipment, resulting in severe wear on some grinding heads; inadequate cleaning tools leading to incomplete cleaning; poor adhesion of the applied asphalt oil; improper selection of construction methods, resulting in poor grinding quality, insufficient application of asphalt oil, and significant initial wear; and the influence of weather conditions, such as road surface humidity and water accumulation.

2. Solutions: Currently, there are two methods for removing old road markings in China: one is the grinding method, which is only suitable for asphalt pavements and is carried out using a hot-melt old marking removal machine; the other is the paint covering method, which is suitable for both asphalt and cement pavements. Grinding involves using an engine to drive a high-speed grinding head made of hard alloy. The grinding head, under centrifugal force, grinds against the raised parts of the road surface, removing the old road markings. This method, using a hot-melt old road marking removal machine, often causes varying degrees of road surface damage and frequently leaves a certain number of markings behind.

3. Paint covering has a relatively small impact on the road surface. In China, black paint is commonly used for covering. However, this method, after a period of wear, leads to paint peeling, necessitating repair and maintenance.

What type of road marking removal machine is used?

Choosing the right road marking removal machine can be difficult for non-professionals to understand, as each type has its own advantages. Ultimately, the choice depends on the application scenario and the client's budget.

For example, in urban areas, for small-area road marking removal, the TianTu alloy blade/steel brush road marking removal machine is suitable. Of course, TianTu's water-cooled road marking removal trucks can also be used, but it depends on the client's needs and financial resources.

What types of road marking removal equipment are available?

Depending on road conditions, a single road marking removal machine is generally insufficient for continuous, uniform, and large-scale road marking removal tasks. Larger equipment or other auxiliary equipment may be needed, depending on the specific circumstances.

1. For small-area road marking removal in urban areas, an alloy blade/steel brush type road marking removal machine is sufficient.

2. For large-area or highway road marking removal, a TianTu high-pressure water removal truck can be selected.

3. For airport adhesive removal, a dedicated airport adhesive removal truck can be chosen.

The above is just a simplified overview of road marking removal. A customized solution will be needed based on the client's specific needs. Having a general idea is sufficient.
