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 asphalt base course excluding December pu or little wax containing 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, oil content of 5.8-6.4%, the bonding layer of gravel diameter 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 pitch, 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 silicon pu play tennis, to ensure that the plastic layer and the foundation has sufficient bond strength. According to the structure of its plastic runway construction, materials can be divided into: prefabricated plastic runway, all plastic plastic track, mixed plastic track, composite plastic runway, breathable plastic track, EPDM plastic runway. Prefabricated plastic track and all plastic plastic track its unparalleled performance is a common type of excellent professional track and field stadium, but its high price, is the general schools and can not afford; mixed plastic track and complex plastic runway performance between all plastic and breathable, the price slightly lower than all plastic, such as plastic runway, but also a lot higher than the breathable, on the basis of higher; breathable plastic runway performance fully You can reach GB / 14833-93 indicators and breathable permeable, short construction period, the renovation is also easier to maintain, the highest price. These products contain a urethane rubber crumb mixed resin layer of the main surface, and coated with a polyurethane coating an uneven finished surface layer. Crushed by the one-component moisture curing polyurethane resin are mixed in the correct proportions. This very viscous mixture was laying on the basis of mechanical coating spread on the runway, with a ruler to control the thickness of the model. After curing, the two layers of high-quality rubber mixture containing colored polyurethane coating, spraying of the rubber base pad to the final surface layer in the correct traction and resistance against sliding. These systems have many advantages cast elastomeric material, although some poor durability. One of the advantages is their porosity, which means that even slight errors exceed the level permitted area not water. Easy to produce serious damage in individual areas of artificial turf football field, such as the end of the javelin run-up track, high jump take-off point, the starting blocks of the installation area, usually before using the diffuser law last casting, casting resin material with a "strengthened" surface layer. Jiangsu good material to protect the plastic track, these systems probably contains the most commonly used combination of laying motion scenes layer of synthetic material, is the first choice in schools of.
