An overview of breathable plastic track 
 Breathable plastic track is the introduction of advanced technology from abroad, has become China's large professional digestion, in primary and secondary schools the most popular track and field stadium, according to incomplete statistics, breathable plastic runway, primary and secondary schools plastic pavement proportion occupies 63%. Breathable plastic track is widely used in the United States, Germany, Italy, Japan, Korea, France, Australia and other countries. 
 Its characteristics are: 
 One does not bubbling: bottom single liquid type PU with elastic rubber particles combining, for environmentally friendly products, with breathable. At high temperatures, the foundation of the steam, will soon be distributed out. Steam pressure can not be gathered, so it will not produce the bubbling phenomenon, and in accordance with professional requirements, and good flexibility. 
 1, the surface layer of EPDM (ethylene propylene diene monomer) rubber, with Practice has proved that a high degree of UV resistance, no fade, strong wear. 
 Can not afford to grain, the surface layer of EPDM (ethylene propylene diene monomer) rubber and polyurethane slurry, pre-mixing of the polymer, using mechanical spray for construction. 
 3, excellent weather resistance, not aging. 
 4, elastic stability throughout the year flexibility undifferentiated, never winter hard summer soft. 
 5, force rotation and shock-absorbing power, emphasizing comfort and safety of athletes to help the athletes to play or improve performance. 
 Stressed the runway the overall performance, and adapt to the various projects and long-term competition and training. 
 7, drawing lines is not easy to Diaoqi, vivid color, fade, wear resistance better. 
 8, the flatness of the IAAF standard, good treatment, rain days do not need to stop the race, immediately after a heavy rain, the game will not water. 
 Amazing time limit: 400m runway plastic surface construction time of 22 working days. 
 Breathable plastic track professional plastic track sets of construction equipment, mechanically constructed to ensure that the duration be completed on schedule. 
 Breathable plastic runway, sports venues, beautiful colors, the site clean and easy to maintain management and not the impact of climate and other conditions. 
 Breathable plastic track process: 
 Cement concrete or asphalt concrete surface layer of clean-up → dilute acidic water to wash cement concrete or asphalt concrete surface layer → water washing again → measurement of cement concrete or asphalt concrete surface layer, underlined → PU glue coated cement concrete or asphalt concrete surface → laying → measure draw regulatory lines →, screed paver track → pavement black rubber underlying → EPDM plastic surface layer of spray adhesive to clean surface. 
 Breathable plastic track is currently no national standards, to provide data users and the physical properties and mechanical properties of the inspection department with reference to the implementation of corporate standards. Reference to the relevant standards of the IAAF acceptance in the relevant national acceptance inspection of the department. 
 Breathable plastic track the scope of application: 
 Applies across the whole primary and secondary schools, the climatic conditions in the areas of more than -16 degrees, do not use the alpine snow and ice areas
