Permeable polyurethane spray plastic track is a double track system. A base layer of black polyurethane resin bonded green rubber particles, the surface layer of colored EPDM rubber particles are mixed with the polyurethane after direct injection by the SMG machinery on the surface layer is formed. (Performance can be achieved GB / 14833-93 indicators of long-term production of plastic track stadium, and breathable permeable, short construction period, the renovation is also easier to maintain, the highest price, is the first choice in schools of) the requirements of construction plastic runway plastic runway Construction of asphalt or concrete foundation, foundation practices and road construction about the same. Higher base surface flatness requirements to ensure consistency plastic surface layer thickness, elasticity even on the basis of quality requirements are as follows: 1 slope: horizontal <1% (curve 8 ‰, straight 5 ‰, semicircular area 5 ‰), Portrait <1 ‰, high jump area <0.4%, the surface should be flat, smooth, smooth drainage. 2. Flatness: Flatness pass rate above 95%, three meters straightedge error 3mm. 3, positioning: the exact construction and draw lines, need for strong distinctive markers mark the four semi-tangent points and two runway center site. 4. Drainage: drainage system is necessary in two hours after the rain water discharge. In the frozen area, between the asphalt layer and add a layer of gravel layer is preferably a cloth buffer layer. Drainage trench along the foundation should do special water treatment. 5, the strength and stability: the foundation should have a certain strength and stability, even a solid surface, no cracks plastic runway, no bad side seams straight and smooth. Cushion compacted plastic track laying, the density of greater than 95%, after the medium-sized rolling machine pressure, no significant wheel tracks, loose topsoil, waves and other phenomena.
