① Stadium foundation layer

The foundation is generally based on cement or asphalt, with a cast-in-place thickness of 100-200 millimeters. After pouring, the curing period is about 28 days, and the water content of the foundation does not exceed 8% before the surface layer can be constructed. The thickness of the asphalt foundation is generally 100mm, and the curing period after compaction is one week before the surface layer can be constructed. Before constructing the surface layer, the cement foundation must be polished throughout the site. The expansion joint of the cement foundation should be cut into a V-shaped shape and cleaned with clean water and dried in the sun before applying a single component EPDM adhesive. The asphalt foundation must have no moisture or soil on the surface before construction.

② Sealing primer layer

Both cement and asphalt foundations can be directly applied with a single component runway adhesive while rolling and coating the next layer. If the adhesive is thick, some leveling agent can be added and stirred before use. Remember not to add other diluents.

③ Runway particle bedding

The particle base layer is divided into a colored particle layer or a black particle layer. The colored particle layer consists of 7 kilograms of particles with 1 kilogram of adhesive and 7.5 kilograms of black particles with 1 kilogram of adhesive. After mixing evenly, the layer is spread and leveled in one go using a paver according to the design thickness.

Only when the entire site is completely dry and not sticky can the next layer of process be constructed.

④ One layer of runway spray surface

After mixing with two components of 1:2PU, spray particles, runway specific catalyst, and leveling agent, use a set of ingredients: 20kg spray B material red color paste, 10kg spray A material glue, 25kg spray particles, 0.15kg runway specific catalyst, and 1.5kg leveling agent. Mix them all together, and then use the runway spraying machine to spray in the reverse direction of left and right in the entire field.

The next layer of work can only be carried out after the entire site is completely dry.

⑤ Runway spray surface second layer

Similarly, mix with two component 1:2PU+spray particles+runway specific catalyst+leveling agent, and then use a set of ingredients: 20 kilograms of spray B material red color paste+10 kilograms of spray A material glue+25 kilograms of spray particles+0.15 kilograms of runway specific catalyst+1.5 kilograms of leveling agent. Mix all together and evenly, then use a track spraying machine to spray the entire field in the opposite direction of one layer of spray layer in reverse order.

The next layer of work can only be carried out after the entire site is completely dry.

⑥ Runway drawing layer

The runway marking paint is our company's specialized oily marking paint. The main agent is 3kg white, mixed evenly with 2kg transparent curing agent, and then sprayed with a runway marking machine or air compressor.
