The soil material should be cohesive fine-grained soil with a particle size of not more than 15mm

Flatness: The qualified rate of flatness is above 95%, and the error of 3-meter ruler is 3mm.

Slope: horizontal <1%, vertical <1‰, high jumping area <4‰, the surface should be flat and smooth to ensure drainage.

Strength and stability: Asphalt materials should preferably use materials with no or little wax content. The base surface must be fully compacted to ensure smoothness without cracks, accumulation of rotten edges, and smooth and smooth joints.

Warranty Period: Basic Warranty Period 28 days.

Notoginseng lime soil foundation

Material ratio: The soil material should be cohesive fine-grained soil with a particle size of not more than 15mm, the sulfate content should be less than 0.8%, the organic matter content should be less than 10%, and the lime should be slaked lime powder with a grade of not less than III. After selecting qualified soil materials and lime, do a 3:7 lime soil compaction test, and the inspection quantity is inspected once every 5000m³ (heavy compaction), so as to control the construction quality.

Water content: The control of water content is a key link. Generally, the water content should be controlled at 20% to 23%, and the maximum should not exceed 24%. Before construction, parameters such as the control range of soil moisture content, the thickness of ash-laying soil, and the ramming and rolling variables should be reasonably determined according to the project characteristics, design compaction coefficient, soil types, and construction conditions.

Compaction standard: compaction coefficient K≥0.95.

The above foundations are suitable for the installation of artificial grass. Choosing the foundation for the appropriate project will help you complete the installation of the artificial grass sports field system.
