EPDM particle construction technology
● requirements for foundation bottom
1. Asphalt concrete or cement concrete can be used for foundation pavement, and it is required to have certain strength and stability (cement concrete foundation needs to cut expansion joints, and waterproof layer is not required).
2. Cracks and uneven frost heave caused by freezing are strictly prohibited.
3. The foundation must have good levelness and specified slope.
4. The surface must be flat to ensure drainage.
5. Mend the seam with glue.
6. The foundation surface shall be kept clean and dry. After the foundation is completed, the maintenance period of more than 21 days shall be strictly required.
● construction process requirements
1. Construction classification: there are two kinds of construction technology, mechanical paving and manual paving. The mechanical paving has good compactness and flatness. Generally, it can be spread by machine when it is higher than 7mm.
2. Surface preparation
On the basis of meeting the requirements, the surface shall be cleaned with butyl first, and there shall be no dirt, dust, water (including watermark), oil stain, etc. After cleaning, evenly apply 0.2kg of primer (mix the diluent: glue in the proportion of 3-4:1) on the foundation to enhance its adhesion to the ground and avoid irreparable consequences.
3. Before construction, the following problems must be paid attention to
a: The use of materials, such as material ratio, whether the material curing time is normal.
b: After 24 hours, observe whether there is any unsteadiness and whether the adhesion, strength and other properties meet the requirements.
4. Pre job preparation (manual)
Preparation of materials, tools and equipment (clapper, roller, soap water, truck, rake, mixer, etc.) and diluent.
5、 Construction personnel requirements (manual)
The minimum number of construction personnel for the runway of the standard yard shall not be less than six: two for material preparation, two for material transportation and two for paving.
6. Construction (manual)
Small area (within 1000 square meters) can be made by bread machine. If there is no condition, you can put it on the ground directly for mixing, and change the place for mixing. Mix the materials according to the proportion, pour them into the site and pave them. Use the clapper after heating (heating by blowtorch) or moistening with soap water to compact and flatten the joint to keep the whole flat. The thickness of the site is generally 6mm
8. After complete curing, draw a line.
9. Construction precautions (manual)
1) The best construction temperature is 15-35 ℃, which is too high or too low, affecting the construction.
2) The spreading tool used (commonly known as trowel or pusher).
3) The mixture must be fully and evenly stirred.
4) Every batch of materials should be well connected, otherwise there will be joints if the connection is not good. Be sure to trim the edges neatly.
5) The ingredients must be strictly proportioned. Depending on the particle situation, less glue is used for the good and more glue is used for the bad; less glue is used for the large and more glue is used for the small. Bottom rubber particle: glue = 8:1; surface EPDM particle: glue = 6:1,
6) After the site is completed, check and clean the remaining things left on the site to make the whole site beautiful.

Air permeable plastic runway
1. All weather: in any season and temperature difference, the quality shall be kept at a high level, which can be used after rain to improve the utilization rate.
2. Fast construction: due to the use of special materials, the weather requirements for construction are not high, professional construction machinery is used, and the construction time is shortened.
3. Proper elasticity: porous molding material with moderate elasticity and counter elasticity to reduce sports injury.
4. Strong weather resistance: the special rubber particle surface can resist the pollution of ultraviolet ozone, sulphite and gas, and prolong the service life.
5. High cost performance: no particles on the surface, easy to maintain and save management costs.
Features of the air permeable runway:
The bottom layer is composed of adhesive bonded waste rubber particles, and the surface layer is sprayed with polyurethane particles mixed with rubber paste. Generally speaking, the main track of the air permeable school track is 13mm in color and the auxiliary area in red is 9mm in thickness, and the color is green. Besides other advantages, the air permeable plastic track can also be used all day. It is economical, low in price, and there is no bubble phenomenon. At the same time, it also reduces the investment of foundation funds. It is suitable for the construction of informal track and field fields in primary and secondary schools. The service life of air permeable plastic can reach more than 6 years.
Construction technology of permeable plastic runway
1. First of all, waterproof treatment shall be carried out for the cement foundation, and a layer of waterproof material shall be rolled coated, with the reference amount of 0.2kg/m2
2. Curing and maintenance for 24 hours. After the waterproof material is solidified, pave the bottom layer of the runway. The reference ratio of 3-4mm high elastic particles mixed with high-strength single component glue is 1:6.5, mix evenly and pour into the paver. The laying thickness is 10 mm. Curing and maintenance for 24 hours.
3. Then mix the air permeable surface material with 1-2 mmepdn particles of the same size into the spray gun of the spraying machine and tilt it to 60 ° for spraying in the same direction. After the spraying is completed and maintained for 24 hours, spray again in the opposite direction.
4. After 48 hours of curing and maintenance, the site can be marked.
5. The site can be put into use after 15 days of maintenance.

Construction technology of plastic track
(1) First, check the flatness of the foundation layer and level the concave and convex parts (for example, the cement concrete foundation needs pickling).
(2) Before laying the primer, clean the foundation and prepare the tools for construction
a) Measure the position of the construction line according to the process requirements and put the construction line in place
b) When laying, one-time scraping shall be started from one side of the site according to the width of the site
c) When scraping, the speed shall be uniform, and the exposed bottom, depression and bulge shall be supplemented or scraped in time
d) Check the whole site after glue forming to ensure the thickness of surface glue laying
(3) Spreading of surface adhesive
a) When scraping, try to shorten the interval time of each barrel of glue liquid to make the glue forming speed uniform
b) Observe the thickness of glue surface at all times
C. before the surface adhesive is not cured, spread red particles on the surface adhesive and clean the redundant surface adhesive particles after it is fully cured
d) Spray glue to ensure that the grains do not take off the mushrooms
(4) According to the current track and field facilities standard, the position of the process line is accurately measured and then polyurethane paint brush is used.
