Commonly used landscape grass foundation

There are three types of landscape grass foundation in common use: asphalt foundation, cement foundation, and gravel foundation, which type is mainly determined by local climate, budget, and time. In most areas of the country, cement concrete foundation has become an economical and cost-effective type of landscape grass foundation.

Here is the content:

• Cement concrete foundation

• Asphalt foundation

• Gravel Foundation

Cement concrete foundation

1. Levelness: Levelness pass rate above 95%, 5m straightedge error 3mm.

2. Slope: 3‰-4‰ in center field, tortoise back drainage design. Curve 8‰, straight road 5‰, semi-circular area 5‰, the surface of landscape grass should be flat, and smooth, to ensure drainage.

3. Strength and stability: uniform and solid surface, no cracks, no rotten edges, straight and smooth joints, 6000mm x 6000mm or so cut blocks are good. Bedding layer compaction, denseness greater than 95%, after the medium-sized mill pressure, no significant wheel tracks, floating soil loose, waves, and other phenomena.

4. Water barrier: adopt new PVC thickened water barrier film, the lap should be more than 200mm, and the margin is more than 150mm.

5. Maintenance period: the foundation of landscape grass maintenance period is 21 days.

6. Positioning: for accurate construction and line drawing needs, the application of firm and distinctive markers to mark out the lines of the site.

Asphalt Foundation

1. Levelness: the foundation should have a certain strength and stability, the foundation of landscape grass cannot produce cracks and uneven frost swelling caused by freezing, levelness pass rate is 95% or more, 3 meters straightedge error 3mm.

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

3. Strength and stability.

Asphalt base preferably uses no wax, or wax containing little asphalt material, its asphalt mixture must be fully compacted. The surface is uniform and solid, flat and without cracks, with no rotten edge pile extrusion, and no pockmarked, smooth, and smooth joints. Asphalt concrete surface layer gravel diameter of 2-5mm, containing 5.8-6.4% oil, joint layer gravel particle size of 6-9mm, containing 4.6-5.8%, no soft skin, no loose floating soil, waves, and other phenomena.

4. Drainage: The drainage system must discharge water after two hours of heavy rain.

5. Maintenance period: 28 days for the basic maintenance period.

Gravel Foundation

A landscape grass foundation is the most economical and applicable foundation with good drainage performance and the lowest cost;

Suitable for the construction of the original site foundation has been a very stable site.

Foundation drainage: water test, drainage after 120 minutes after the rain, water is allowed to exist but the thickness of water shall not be greater than 4mm.

Drainage slope: After the foundation of landscape grass is completed, put a 10×10m square grid to remeasure the elevation and calculate the drainage slope, the drainage slope is ≤0.7% and the error is <1.5%.

Compactness: The compactness of the stabilized layer shall not be less than 93%.

Qualification rate: The qualification rate of levelness, slope, and site elevation shall be 85% or more.

Thickness error: thickness tolerance ±10%.
