Pu basketball court

Pu basketball court:

Pu plastic material characteristics:

All weather: maintain a high level of quality in any season and temperature difference. It can be used immediately after rain, increase the use time and improve the utilization rate of the site:

Elasticity: it has moderate elasticity, which can reduce physical consumption and improve competition results:

Impact absorption: moderately absorb the impact of feet, reduce sports injuries, and meet the requirements of long-term training and competition:

Weather resistance: it will not fade, pulverize or soften due to UV, ozone, wind and rain, sulfite and gas pollution, and can maintain its bright color for a long time:

Wear resistance: the wear resistance is small, which can meet the needs of long-term high use frequency.

Quality requirements of Pu basketball court for asphalt Foundation

The requirements for the flatness of the foundation surface are high, so as to ensure that the thickness of the plastic surface layer is consistent, the elasticity is uniform, and the plastic surface material is not wasted.

No matter what foundation is adopted, it shall have certain strength and stability. The foundation shall be free from cracks and uneven frost heave caused by freezing. The foundation shall have a certain Flatness: the qualified rate shall be more than 95%, and the error of 3M straight edge shall be 3mm. Certain gradient: transverse < 1%, longitudinal < 1 ‰, high jump area < 4 ‰, and the surface shall be flat and smooth to ensure drainage.

It is better to use asphalt materials without or with little wax for asphalt foundation, and its asphalt mixture must be fully compacted. The surface shall be uniform and solid, flat, free of crack, rotten edge extrusion, pitted surface, and the joint shall be smooth and smooth. The particle size of gravel for asphalt concrete surface course is 2-5mm, the oil content is 5.8-6.4%, the particle size of gravel for joint course is 6-9mm, the oil content is 4.6-5.8%, and the asphalt softening point is 82-104 ℃.

The compaction compactness shall not be less than 95%. After being rolled by the medium-sized roller, there shall be no significant wheel trace, softening and peeling, loose floating soil, waves and other phenomena.

The foundation must have a water resisting layer.

The drainage must be discharged two hours after heavy rain according to the requirements of Party A. Therefore, the drainage system shall be considered.

The basic maintenance period is 21 days.

Quality requirements for cement foundation

The requirements for the flatness of the foundation surface are high to ensure that the thickness of the reverse glue surface layer is consistent and the elasticity is uniform. The pass rate of flatness is more than 95%, and the error of 5m straight edge is 3mm,

Gradient: 8 ‰ in transverse direction, 5 ‰ in longitudinal direction and 5 ‰ in semicircular area. The surface shall be flat and smooth to ensure drainage.

The foundation shall have certain strength and stability.

The surface shall be uniform and solid, without cracks, rotten edges and pitted surfaces, and the joints shall be straight and smooth, with a thickness of 6000mm × It is better to cut about 6000mm.

The cushion shall be compacted, and the compactness shall be greater than 95%. After being rolled by the medium-sized roller, there shall be no significant wheel trace, loose floating soil, wave and other phenomena.

The cement foundation must be provided with a water resisting layer. The water resisting layer adopts new PVC thickened water resisting film. The junction shall be greater than 300mm and the edge allowance shall be greater than 150mm.

The basic maintenance period is 21 days.
