Adhesive stone permeable pavement is made of natural colored stone and high weather-resistant silicone modified polyurethane resin by special process, which has the characteristics of strong and beautiful, natural and dazzling color, and is not easy to fade, and is a novel artistic landscape pavement material. Adhesive stone permeable pavement has ecological, permeable, breathable and good anti-skid function, and is environmentally friendly, non-toxic, no radiation, no environmental pollution, and is a breathable ecological ground.
1.Excellent beautification effect.
2.Prevent water accumulation, which can quickly seep into the ground when it rains. People and bicycles are safe and clean.
3.It replenishes water to the ground, maintains ecological balance, and alleviates the heat island effect.
4.Prevent unclean water from the road from flowing into the vegetated area and causing damage to the growth of vegetation.
5.It is not easy to accumulate snow and improves traffic safety.

Adhesive stone construction technology.
Step 1: Adhesive stone material selection
1. The stones used are called washed stones, glued stones, washed rice stones, etc., which are called differently and are the same.
2. The stone used must be dry, and there can be a small amount of stone powder that does not affect the effect, but there must not be a lot of stone powder.
3. If the stone has been ground and has not been polished, it shall be selected according to Party A's requirements.
4. The glue should be made of adhesive materials with good outdoor durability and not easy to yellow, and high-grade polyurethane and epoxy resin should be recommended for outdoor chalking.
Step 2: Preparation before construction.
1.Permeable adhesive stone is used as a load-bearing pavement, which is generally designed to be 2-4 cm thick on the hardened pavement such as cement pavement or permeable concrete pavement, and it is not recommended to do it directly on the basis of plain soil. Used as a tree pond, it can be made on a plain soil foundation.
2.The tools required are: preparation bucket (as far as possible more than 25L drum), portable stirring, kilogram scale, grinding disc mixer, shovel, trowel, water basin.
3.Before construction, the foundation pavement should be cleaned, and no soil, no stagnant water, and no oil stains should be left, otherwise there will be bubbling and delamination, which will affect the delivery.
4.Small sites can be mixed manually, and larger sites can be mixed with mixers. According to the different particle size of the stones, the ratio used is different. The larger the stone, the less glue is used. 0.3--2 cm can be used 30:1 dosage, and do a test section to see the bonding effect. If possible, a grinding disc mixer can be used for mixing.
3. Construction. Before construction, the elevation line is played according to the design elevation. Mix well with the stones at a ratio of 30:1 or the expected ratio and start paving. There are usually 4-5 people left at the paving site. Now the material is preliminarily leveled, and then accurately leveled by hand. The construction time is less than 60 minutes in summer and can be extended in winter. It is not recommended to stir too much material at one time, as it will cause the material to become sticky and difficult to level. Large-area construction can be smoothed with a cement trowel.
The initial viscosity of this product is very small, and it does not stick to the trowel, so it does not need to be dipped in water. The glue can also be diluted with a thinner, and the diluents that can be used are dichloroethane, ethyl acetate, pure xylene. It is strictly forbidden to use diluents containing hydroxyl groups such as banana water, ethanol, etc. In general, there is no need to add any diluent at all.
Fourth, after the completion of construction, the construction site should be blocked in time, and personnel are strictly prohibited from moving. Generally, pedestrian traffic can be opened after 6 hours of solidification, and family cars can be opened after 24 hours. The full strength of this product should be around seven days.
Precautions: For large-area continuous construction, it is recommended to use construction joints to prevent alternating frost heave of cold and heat.
If the glue is not used up to a bucket, it should be sealed in time to avoid the reaction and cannot be used.
It is strictly forbidden to use diluents containing hydroxyl groups such as banana water, ethanol, etc.
