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 of more than 95% pass rate in the runway, 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, no pockmarked face, seams are smooth. Asphalt concrete surface layer of gravel diameter of 2-5mm, the oil content of 5.8-6.4% plastic runway construction, bonding layer of gravel particle size of 6-9mm, the oil content of 4.6-5.8%. The degree of compaction of not less than 95% dense, 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. Schools need to pay attention to the construction plastic runway contaminated runway until now most of our plastic used in plastic, is made of polyurethane industry is diethyl toluene diisocyanate silicon pu stadium runway, made of a material called TDI playground plastic runway, made of plastic and then adding a binder, curing agent, laying on the runway, they built a plastic runway. Whether diethyl toluene diisocyanate or curing agents, adhesives, are all organic compounds, they are hot and strong light, it will volatilize irritating gases. There are many businesses in order to collect more benefits there are to use this material TDI, especially polyurethane plastic runway, the kinds of plastic runway easy threshing, fade. But the majority of our schools or the use of plastic track. Suggested that schools in the selection of plastic track time, focus on quality, brand and environmental performance plastic runway. The student's safety first. Plastic runway construction _ Camry sports (certified) _ Liaoning runway provided by the Dongguan City Camry sports facilities Engineering Limited.
