High Resilience Sandwich System Running Track Mixed Polyurethane Running Track

• High resilience & dense structure
• PU binder mixed with rubber granules (approx. 25%-30% content)
• Spikable surface for competition use
• 8-12 years service life
• Compliant with World Athletics standards

The Mixed Running Track is a dense elastic system formed by mixing polyurethane (PU) binder with rubber granules (approximately 25%-30% rubber granule content) in a specific ratio, troweling onto asphalt or concrete base, then applying a pure PU top coat and scattering EPDM anti-slip granules, with a total thickness of 13mm. The elastic layer has high density and strong rebound. It is currently the only plastic surfacing material with a national standard, mainly used for professional competition venues and training bases.

✅ Ideal for: professional athletics competition venues, sports university training fields, international school sports fields, provincial/national sports centers, high-frequency professional training bases.

✅ Mixed vs Composite vs Porous: Mixed track adopts PU binder mixed with rubber granules in the elastic layer, high density, spikable, suitable for high-intensity competition use. Composite track applies a PU slurry over a porous elastic layer followed by a spray coat, with performance between porous and mixed. Porous track has an open-cell structure, water-permeable and breathable, but lower spike resistance and rebound.

✅ All data can be supported by third-party test reports (SGS, TÜV, etc.) according to World Athletics (ex-IAAF) recommendations for competition and training tracks.

Key feature: The elastic layer adopts PU binder mixed with rubber granules, higher density than porous and composite tracks. Top layer can be scattered granules or sprayed textured finish (customizable). Strong rebound, spikable (accepts ≤9mm spikes), long service life.

We offer two sources of granules:

✅ Both types can be used in mixed track systems. For the elastic layer, we recommend using 25%-30% recycled black granules mixed with PU binder. For the top layer, virgin EPDM granules are recommended for best performance and appearance.

✅ Note: Mixed tracks are available in two top surface types – spray-coated type (PU mixed with EPDM granules sprayed) and scattered-granule type (EPDM granules scattered over pure PU slurry). Customizable upon request.

1. What is the difference between mixed track and composite track?
   → Mixed track uses PU binder mixed with rubber granules (approx. 25%-30% content) to form a high-density elastic layer with strong spike resistance, suitable for professional competition venues. Composite track applies a PU slurry over a porous elastic layer followed by a spray coat, with performance between porous and mixed, but less durable and stable than mixed track.
2. Is the mixed track suitable for rainy regions?
   → Mixed track is a dense, non-permeable structure. The base layer must be properly waterproofed and the site must have a good drainage system. Its advantage is that the surface does not absorb water, allowing quick resumption of use after rain.
3. Can the mixed track accept spiked shoes?
   → Yes. Mixed track has strong spike resistance and can accept ≤9mm spikes. Professional sprint spikes (≤9mm) can be used normally without damage, even at high-frequency areas like the 100m starting zone.
4. What is the service life of mixed track?
   → Under normal use and maintenance, mixed track lasts 8-12 years, longer than porous track (5-8 years) but slightly shorter than full PU track (10-15 years).
5. Can I buy only materials without installation service?
   → Yes. We focus on material supply and provide full drawings and guidance for self-installation, or can recommend local contractors.
6. What is the MOQ?
   → No minimum. Any quantity from a few drums/bags to thousands of tons.
7. What binder packages are available?
   → Standard 200kg steel drum; also 20kg plastic drum for easy handling and small jobs.
