Hybrid plastic runways are laid using a three-step construction method.
1. PU base coat
Acceptance of the asphalt foundation, if the asphalt foundation of the surface gap is relatively large, before paving to carry out anti-seepage treatment, anti-seepage layer is a two-component hybrid runway special paving materials A, B components of the material in accordance with the prescribed ratio of proportioning, mixing, and remember to add an appropriate amount of catalyst according to the changes in temperature and humidity, composed of hybrid runway special paving composite material, in which to add an appropriate amount of quartz sand for the batch scraping Add appropriate amount of quartz sand to batch and seal the bottom, and wait for its curing.
2. PU elastic base layer
Add an appropriate amount of black rubber granules to the well-mixed composite in the specified proportion and batch scrape it into an elastic layer with a thickness of 8-9 mm.
3. EPDM anti-slip wear-resistant surface layer
Currently there are two practices, spreading granules and spraying:
Spreading rubber grain process is in the elastic layer above the batch thickness of 2 mm of integrated material, with artificial evenly sprinkled with EPDM rubber grain or PU rubber grain, to be cured after the excess EPDM rubber grain is not adhered to the surface of the swept away, and finally sprayed a layer of reinforcing adhesive on the top;
Spraying process is to add the appropriate amount of spraying material to the EPDM adhesive particles stirred well, and sprayed directly on the surface of the elastic layer with special spraying equipment.
