What kind of spraying material is used for road surface color change?
2 Answers
When selecting materials for road surface color change, pay attention to the following points: 1. Color: The most important aspect of color-changing roads is vibrant and long-lasting color. 2. Adhesion: It must fully bond with the original road surface to ensure construction quality. 3. Durability: It should resist UV rays, heat, and freezing. A specialized road spray that meets these requirements is suitable. In China, colored asphalt pavement can be divided into two main types: 1. The first type: Uses transparent or semi-transparent asphalt binder as the bonding material, then adds inorganic pigments to the asphalt mixture. 2. The second type: Uses transparent or semi-transparent binder and selects natural colored mineral aggregates for mixing.
I usually work on road surface projects, and the most commonly used material for color-changing spraying is epoxy resin because it's sturdy, wear-resistant, and doesn't fade, even with heavy vehicle traffic. Before spraying, the ground must be thoroughly cleaned—absolutely no oil stains or dust, otherwise it won't adhere properly. After spraying, an anti-slip granular layer is added to ensure safety during rainy days. Summer is especially suitable for construction as it dries quickly, allowing traffic to resume in just two hours. For long-lasting durability, remember to choose two-component epoxy—single-component types are cheaper but prone to cracking. As for colors, nowadays red, yellow, blue, and green can all be mixed. We recently completed a gradient-colored community walkway, and it looks absolutely stunning.
