① Runway 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. After polishing, clean with clean water and dry in the sun before applying the primer. The asphalt foundation must have no moisture or soil on the surface before construction.

② Sealing primer layer

Cement foundation, using a single component penetrating primer, directly open the bucket and stir evenly before rolling coating throughout the site. The primer can only be applied to the next layer after it is completely dry and does not stick to the feet.

The asphalt foundation shall be sealed with a special lotion of single component asphalt. The lotion shall be mixed evenly with 1kg+2.5kg sand+2.5kg cement+2.5kg water, and then scraped with a large rubber rake throughout the site, until all asphalt floors are covered with more than 1mm thick, and the next process can be constructed after the whole site is completely dry.

③ PU plus particle mixing layer

After mixing with two components of 1:5PU+particles+track specific catalyst, use one set of ingredients: 50kg of PUB material red color paste+10kg of PUA material glue+20kg of particles+0.3kg of track specific catalyst+1.5kg of leveling agent. After mixing them all evenly, use a thickness ruler and a large iron tooth rake to scrape the designed thickness of the track once on the entire site. If the site is uneven and there is water accumulation, use the same ingredient method to prepare it, and then use aluminum alloy to level it. The next layer of work can only be carried out after the entire site is completely dry.

④ One layer of runway spray surface

After mixing with a two-component 1:2PU, spray particles, runway specific catalyst, and leveling agent, 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, and 1.5 kilograms of leveling agent to mix evenly. 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 transparent.

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.
