Colored asphalt pavement manufacturers explain how to maintain colored asphalt pavement

Colored asphalt pavement adds a touch of color to plain and black pavement, but it also requires preventive maintenance. The importance of preventive maintenance for pavement maintenance is generally attributed to repairs and maintenance on Chinese highways. After a certain number of highway lanes have been opened, repairs are suspended two to three years later. A major reason for this is the lack of preventive maintenance due to the initial costs.

Preventive maintenance, as we call it, involves suspending appropriate repair equipment on the road at a reasonable time, before damage or mandatory measures are taken. If problems are present during maintenance, these problems are addressed at the earliest stage, thus preventing the deterioration of the road's positive functions. When to perform preventive maintenance on a pavement: Highways are a key component of local highway service performance. Highway usage and service quality are closely related to the lifespan of the pavement.
Therefore, the key to pavement maintenance is overall road maintenance. The basic principle is "focus on pavement maintenance while strengthening overall maintenance." When the PCI (Pavement Condition Index) is between 75 and 95, a good road has only a few cracks, each less than 3 mm. Maintain good road conditions and minimize water penetration that could propagate cracks. Simple sealing measures can be employed.
For colored non-slip pavement, when the PCI index is between 60 and 75, it's considered good condition. This is a good time to perform preventative repairs early on. Pausing the pavement can effectively slow down degradation on the road.
