Sandwich Running Track

Product Details

Sandwich system plastic running track sports field because it has a good surface drainage function, the rain and snow in the alpine region into the elastic layer of the plastic runway, once the climate warms up, snow and ice melt in the surface of the sandwich plastic runway through the natural drainage of the runway slope, the runway does not have any adverse effects. Applicable to all kinds of athletic field in the alpine area.

• Features

1. Layered composite structure: bottom elastic particles + middle reinforcing layer + surface wear-resistant layer, scientific layered design.

2. On-site liquid construction: raw materials are laid in liquid state, seamless curing and shaping, strong integrality.

3. Highly adaptable foundation: low levelling requirements for asphalt/concrete foundation, saving the cost of grass-roots treatment.

4. Excellent comprehensive performance: taking into account the elasticity, impact resistance, abrasion resistance and anti-skid.

5. Convenient and economical maintenance: local damage can be seamlessly repaired, low maintenance cost and low impact.

6. Environmentally friendly, durable and reliable: environmentally friendly and non-toxic materials, weathering and anti-aging, long service life.

• Construction Step

Ⅰ. Foundation treatment and inspection:

1. Clean foundation (asphalt/concrete), repair cracks and holes.
2. Key: test the foundation strength, flatness, water content (must meet the standard).

Ⅱ. primer construction (penetration layer):

1. Roll on special primer material to enhance bonding with foundation and close capillary holes.

Ⅲ. Elastic primer paving:

1. Mix polyurethane glue + rubber granules, paving and scraping.
2. Core: control thickness, flatness and elasticity.

Ⅳ. Reinforcement layer construction (key sandwich layer):

1. Scrape and apply high-strength polyurethane slurry layer to form a dense intermediate layer.
2. Role: to improve the overall strength, tear resistance, flatness.

V. anti-slip wear-resistant surface layer spraying / paving:

1. Spraying method: mixed surface layer slurry + EPDM particles, spraying to form texture.
2. Scraping method: scraping with sand surface layer slurry, sprinkle anti-skid particles (optional).
3. Core: uniformity, anti-skid, weather resistance, color consistency.

Ⅵ. Drawing line:

1. Measure and position according to standard size, spray professional sports delineation paint.

Ⅶ. Cleaning and Maintenance:

1.Clean up the site, fully cured (usually takes 5-7 days) before use.
