The main runway surface construction method plastic plastic runway construction plan and a construction program testing standards, clean space asphalt concrete construction is completed, The Nature Conservancy 28 days, clean asphalt surface dust with water cannons, and turn on the water to detect whether the site water, stagnant water chalk recorded and used plastic to fill the flat until no water so far. Second, the formwork to steel tape and theodolite accurate release formwork line plastic track quality is good, and formwork line between the runway center line, die and mold spacing of 2.44 meters (two channel width). Then 11MM mold section according to line accurate expenditure formwork mold frame, formwork primarily to ensure the plastic surface construction thickness (13MM) and flatness. Third, laying plastic surface layer 1, the pre-construction ground moisture determination: a sunny day with a thin transparent sticky tape around the wax on the ground. After two to four hours, if condensation inside the construction is not only in measuring ground water rate of 8% or less plastic runway, before laying the plastic surface. 2, the mixed material mixing: a, stirring place to shop with plastic surface floor heating pad to ensure clean; b, the material is enabled, it must first clean the outer edge of the cover; c, Group A and Group B material according to a predetermined weight proportion into the mixing bucket, then add 20% of black rubber, and a certain amount of curing agent. Mixer should move around, and the material thoroughly mixed, but should avoid air into. 12d, the material should be poured directly into the mixing bucket central plastic track environmental protection, not dumped along the bucket, so the bucket material can not be fully mixed. Plastic playground Features: 1. bright color surface layer can be designed and lively, happy, image and other types of patterns, no seams, a shape, the overall sense. 2. Anti-UV, color stability, do not fade. 3. To cushion protection, nonflammable, engage in aging and difficult to microbial growth. The hydrophobic properties, although, throughout the year to keep the surface layer dry. Maintenance is simple, clean with water or modifications can be. Kindergarten plastic playground acceptance: 1. plastic surface layer of special requirements: (1) the flatness of 3 meters ruler ± 3MM, transverse slope not greater than 1/100 slope inward longitudinal direction of not more than 1/1000; (2) there is a certain physical properties; the base layer (3) plastic surface impervious to avoid warm air to rise and affect the adhesion plastic and asphalt layer; 2. standard: (1) GB / T531 rubber Shore A hardness test methods; (2) GB / T1681 Determination of vulcanized rubber resilience; (3) Standard temperature GB2941 rubber of like environmental regulation and testing, temperature and time; (4) GB9866 vulcanized rubber sample and sample preparation; (5) GB10111 using a random number of dice random sampling approach; (6) GB10633 steel tape measure; (7) GB / T10654 polymer but strength and elongation at break was measured with the hole to pull an elastic material. 3. Technical requirements: (1) Appearance: No cracks or delamination, non-slip layer and bottom layer bonded firmly. (2) flag lines: Standard wire clear, non-glare, no virtual edge, and the surface layer bonded firmly. Multi-position indicator line length distance from the finish line is not allowed negative difference between its positive difference should be less than 1/1000.
