Hybrid construction process

--PU undercoating

Acceptance of the asphalt foundation, if the surface gap of the asphalt foundation 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 proportion, 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 batch scraping Add appropriate amount of quartz sand in it to batch scrape and seal the bottom, and wait for it to be cured.

--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.

-- EPDM anti-slip wear-resistant surface

At present, there are two practices of spreading granules and spraying: Spreading particles process is in the elastic layer above the batch thickness of 2 mm of composite material, manually sprinkle EPDM particles or PU particles evenly, to be cured after the excess EPDM particles not adhered to the surface Sweep off, and finally spray a layer of reinforcing adhesive on the top; Spraying process is to add the appropriate amount of spraying material EPDM adhesive particles stirred evenly, directly with special spraying equipment sprayed on the surface of the elastic layer.

Nanjing Sports Institute Gymnasium

The track and field stadium of Nanjing Sports Institute is one of the projects that our company was responsible for in the early days. The field was first laid in 2001, consisting of a red EPDM surface layer and a black SBR granule base layer, and has been in use for more than 10 years.
