Fine anti-skid surface treatment technology, also known as fine gravel surface treatment technology, referred to as: fine surface treatment. It is an asphalt pavement maintenance technology that uses construction equipment to simultaneously spread (sprinkle) cement and aggregate onto the asphalt pavement in layers and quickly form them through appropriate rolling. It can improve the waterproof and crack-resistant performance and anti-slip performance of the pavement, slow down the occurrence of asphalt pavement diseases, and extend the service life of the pavement.

From the definition, we can clearly understand that the fine surface is mainly laid in layers. According to actual construction needs, there are single-layer paving and double-layer paving on the surface. In a single-layer pavement structure, from bottom to top there are cementing materials, aggregates, and cementitious materials. The double-layer pavement structure is more complex, divided into 5 layers, from bottom to top, cementing material, aggregate, cementing material, aggregate, cementing material. Which method is suitable depends on the road conditions.
The role of the Jingbiao Department is mainly reflected in the following aspects. First, it can improve the waterproof and crack-resistant performance of the road surface. By laying down binders and aggregates, finishing can make the road surface denser and reduce water penetration, thereby reducing the risk of pavement cracking. Secondly, fine surface treatment can improve the anti-skid performance of the road surface. Due to the selection of aggregates and optimization of the paving process, the fine surface pavement can provide better friction and reduce traffic risks. In addition, fine surface treatment can also slow down the occurrence of asphalt pavement diseases. Through regular maintenance of the pavement, minor diseases on the fine surface can be discovered and repaired in time to prevent the disease from expanding, thereby extending the service life of the pavement.
In practical applications, fine surface treatment technology has the advantages of rapid prototyping, simple construction, and environmental protection. By rationally selecting cementitious materials and aggregates, fine surface treatment technology can complete pavement maintenance work in a short time and reduce the impact on traffic. At the same time, construction equipment with fine surface treatment technology can achieve precise proportions of aggregates and cementitious materials to ensure construction quality. In addition, the materials used in the surface treatment technology have good environmental performance and are in line with the development trend of modern green transportation.
