The flatness of breathable plastic runway: the error of 3M ruler at any position is not more than 3mm
.
The flatness meets the standard of IAAF, and the water filtering property is good
.
The first step in the construction process of mixed plastic runway: simple cleaning and flatness integration are needed
.
Permeable plastic runway drainage: the runway should have a slope of about 8 ‰ from the outside to the inside, which can ensure that there is basically no water in the field about 40 minutes after the rain
.
Mix the air permeable spray adhesive with EPDM particles and EPDM powder according to the specified ratio of 1:1:0.2, mix them evenly, pour them into the special spraying machine, and spray them two to three times clockwise and anticlockwise
.
Although it is very simple, but in the actual operation process is to follow certain principles and process
.
Any position of the runway shall not be less than 9mm, and the thickened area (such as pole vault, javelin, long jump runway, high jump thickened area) shall be greater than 18mm
.

.
The EPDM (ethylene propylene diene monomer) particles on the surface layer are mixed with polyurethane slurry and prepolymer, and then mechanically sprayed
.
That is, in the process of laying the surface layer, anti-skid particles can be evenly scattered on the bottom layer glue or protective glue can be brushed on the anti-skid particles; the anti-skid particles and glue of the surface layer are sprayed evenly according to a certain proportion
.
So, what are the construction processes of mixed plastic runway? Are there any rules to follow? 1
.

.
Now the commonly used colors are red and green
.
The upper layer is made of Pu particles or EPDM weather resistant environmental protection color particles mixed with mechanical spraying, and the lower layer is made of mechanical paving cushion

Under high temperature, the steam generated by the foundation will be released quickly
.
Steam pressure can not gather, so it will not produce bubble phenomenon, and meet the professional requirements, good elasticity
.

.
It meets the training standard of professional track and field athletes
.
Step 2: Cement isolation
.
For the surface laying of runway, two processes should be followed, namely, particle spreading process and spray coating process
.
Thickness of permeable plastic runway: the thickness of runway area must be within 13mm ± 2mm, and the qualification rate shall be more than 90%
.
Because of its good air permeability and water permeability, breathable plastic runway is widely adopted in rainy areas
.
Our company adopts the composite structure approved by IAAF

Guangzhou Bo’ao is willing to provide you with reasonable prices, high quality products and technical services
.
Step 1: apply one component glue or primer evenly on the cement foundation with roller brush
.
The data of physical and mechanical properties provided by users and relevant testing departments refer to enterprise standards
.
The elasticity is stable, and there is no difference in elasticity throughout the year
.
Professional production process is simple, the construction period is relatively short 10, the color is beautiful, the site is clean and easy to maintain, breathable plastic runway construction process cement concrete or asphalt concrete surface layer cleaning → desalination acid water cleaning cement concrete or asphalt concrete surface layer → clear water cleaning cement concrete or asphalt concrete surface layer again → measurement, draw bottom line → Pu strong glue coating cement concrete or asphalt Concrete surface course → pave and find paver track → pave black rubber particle bottom course → spray EPDM plastic surface course → measure and draw gauge line → clean surface course
.
It will not be hard in winter and soft in summer
.
Hybrid plastic runway hybrid plastic runway is also known as the traditional runway, with a flat and dense structure
.
Breathable plastic runway features: the bottom layer of breathable plastic runway is a combination of single liquid Pu and elastic rubber particles, which is an environmental protection product with ventilation function
.
Breathable plastic track is suitable for primary and secondary schools all over the country, climate conditions in – 16 degrees above the area, do not use alpine ice and snow areas
.
The fourth step: surface glue laying, in the laying process to keep the glue thickness uniform and level
.
The thickness of auxiliary area should be more than 9mm
.
Acceptance methods and technical standards for breathable plastic runway the physical properties of the acceptance methods for breathable plastic runway meet the above technical standards
.
EPDM (ethylene propylene diene monomer) rubber particles are used as the surface layer to make it highly resistant to ultraviolet rays
.
Construction principle and process of mixed plastic runway 2
.
At present, there is no national standard for breathable plastic runway
.
Breathable runway has the advantages and performance of general runway, and low cost, and has become one of the mainstream products of plastic runway surface
.
7
.
In the inspection and testing of the relevant national acceptance departments, the acceptance shall be carried out according to the relevant standards of IAAF
.
There are many kinds of plastic runways in the construction process of hybrid plastic runways, among which the most commonly used and the most common one is hybrid plastic runways
.
Emphasis on the overall performance of the runway, to adapt to various events and long-term competition training
.
Before the primer is cured, the single component glue and black rubber particles are mixed according to the specified proportion of 8:1, fully stirred by a mixer, transported to the paving place, and paved by a paver according to the specified thickness; after curing, the elastic layer is formed
.
Practice has proved that it has no fading and strong wear resistance
.
The last step is to underline
.
Surface quality of breathable plastic runway: the surface material shall not be threshed, cracked, layered and bulged, and the thickness of wear-resistant layer shall not be less than 2mm
.
After curing, they are anti-skid and wear-resistant layers

.
Excellent weather resistance, not easy to aging

.
The third step: to lay the primer, it is necessary to clear the bottom layer, complete the construction area, and scrape the glue to form glue
.
Construction process of mixed plastic runway 2
.
There is no need to stop the competition in light rain days, and the competition can be carried out immediately after heavy rain without ponding
.
It is a common type of high-end track and field sports ground, and its cost is much higher than that of the breathable type.
.
It emphasizes the comfort and safety of athletes, which is helpful for athletes to play or improve their performance
.
Features and uses: good fluidity, fast crosslinking speed, environmental protection, good elasticity, easy construction, suitable for mixing with rubber particles
.

.
The hybrid plastic runway is generally used in professional competition venues
.
There are certain requirements for the marking on the plastic runway, which should be strictly observed
.
Whether it is the laying of the primer or the surface glue, it should be completed as soon as possible in the laying process, and the thickness of the glue surface should be ensured, and the unqualified parts should be repaired in time
.
Color of breathable plastic runway: the color of each area should be basically uniform, and the runway with multi-color design should not dazzle or cause confusion of related events
.
