The main components of eco - plastic racetracks are acrylic and high quality resins, which are similar to the convenient bags of food and are in line with the requirements of environment-friendly surface materials. The raw materials of the plastic racetrack have been certified by the national plastics industry association, which is harmless to the environment and human body. It has the characteristics of anti-ultraviolet, anti-wear, anti-blowout, anti-aging, long life, easy maintenance and low maintenance cost.
The basic quality requirements are as follows:
1. Slope: horizontal <1%(8‰, 5‰, 5‰), vertical <1‰, high jump area <0.4%, surface should be smooth and smooth and unobstructed.
2. Flatness: the proportion of the flatness of the flatness is over 95% and the error of 3 meters is 3mm.
3. Positioning: the four semicircle tangent points and two centers of the track field are marked with strong and distinct markers for accurate construction and drawing lines.
4. Drainage: the drainage system must discharge water in two hours after heavy rain. In the frozen area, the layer between the asphalt layer and the gravel layer should be added with a layer of geotextiles. Special waterproofing should be made on the base of drainage groove.
5. Strength and stability: the foundation shall have certain strength and stability, the surface is uniform and firm, no cracks, no fraying edges, and the joints are smooth and smooth. The cushion compaction is more than 95%, and after the medium roller compaction, there is no obvious wheel trace, loose soil, wave and so on.
