EPDM construction of a stadium. Check whether the foundation construction: foundation flatness, drainage slope, density (cement base grade of not less than C20, asphalt surface density of the solid foundation of the more than 90%), be sure to keep the site before construction dry sports plastic track, can not have water. 2. Survey Site area: Learn quantities (construction area), engineering content (what types of products), to calculate the amount of materials needed for each side of the cottage, and then live material inventory, calculate the total amount of material is enough to complete the project amount to at the construction process with the use of proper materials, does not cause enough or have more material remaining at the end of the project. 3, the end of plastic laying: a) in accordance with the process required to measure the position of the construction line, put away the construction line. b) start laying side by site, according to the width of the one-time site scraping gum. c) even when the squeegee speed, timely show the bottom of the depression, were raised at the glue or gelling. d) After a gel, for the audience to check playground plastic runway to ensure that the surface of plastic laying thickness. 4, rubber paving: minimize the time a) intervals for each barrel scraping gum glue, making uniform gelation speed. b) the thickness of the plastic surface observation time. c) ensure that particles do not fall off. 5, according to the current planning process line spray athletic venues and facilities standards to accurately measure the position of the processing line, and then use polyurethane paint airbrushed plastic runway paving asphalt or concrete foundation, foundation and road construction practices roughly the same. Whether asphalt or cement foundation, and its surface flatness higher, in order to ensure a time, the elastic plastic layer thickness uniformity, and does not waste rubber. On the basis of quality requirements are as follows. 1) Flatness: foundation should have a certain strength and stability. Foundation cracks and not due to uneven heaving caused by freezing. Flatness pass rate above 95%, 3 m straightedge error 3mm. 2) slope: horizontal <1%, vertical <1 ‰, high jump area <4 ‰, flat, smooth surface should ensure drainage. 3) the strength and stability: ① the best use of the asphalt base without wax, wax-containing little or asphalt material, which must be fully compacted asphalt mixture. Solid surface evenly, smooth and no cracks, no bad side heap crowded stadium runway project, lint-free surface, the seams are smooth. Asphalt concrete surface layer of gravel diameter of 2-5mm, oil content of 5.8-6.4%, the bonding layer of gravel diameter of 6-9mm, the oil content of 4.6-5.8%. Compaction of not less than 95% of the density of the runway, after the medium-sized rolling machine pressure, no significant wheel tracks, no weak from the skin, no topsoil loose waves and other phenomena. ② uniform solid concrete surface, no cracks, no bad side seams straight and smooth, with about 6000mm × 6000mm cuts as well. Cushion compaction, density greater than 95%, after the medium-sized rolling machine pressure, no significant wheel tracks, loose topsoil, waves and other phenomena. Cement concrete foundation impermeable layer to be added: the introduction of new thick impermeable PVC film, lap should be greater than 200mm, edge margin greater than 150mm. 4) Drainage: drainage system in two hours after the rain water discharge is necessary. 5) maintenance period: the foundation surface should be kept clean and dry asphalt base after the completion of more than 30 days of maintenance requirements, in order to make the asphalt surface of the low-boiling components to play to ensure that the plastic layer and the foundation has sufficient bond strength. 6) the base surface to be kept clean and dry asphalt base after more than 30 days of the completion of the requirements of maintenance, so the asphalt surface of the low-boiling component to play to ensure that the plastic layer and the foundation has sufficient bond strength.
