Plastic runway paving - Plastic runway paving attention to the problem
(1) polyurethane plastic materials in the construction process is most afraid of water, paste in the initial curing before touching a drop of water will produce a large bubble, so the construction workers in the high temperature conditions should be prepared to towel sweat. Pave the rubber surface must grasp the weather conditions and to do a good job to prevent sudden showers of emergency measures. Paving time to avoid the morning in the atmosphere and the ground humidity is greater, even in the weather clear normal working day, generally the best in the morning after nine o'clock formally paved,hollister france, plastic runway paving.
(2) The solid thickness of the adhesive surface refers to the center of the adhesive particles from the adhesive bottom to the surface layer, and is generally controlled from two aspects. First of all, through the mold for the thickness of the size of the pre-check, the grass-roots level of the local high places to repair cut or hammer tamping low. If not much higher, can be used on a flat scraper with a clamp off the mold scraping slurry to ensure the thickness of the 11th Asian Games North Suburban Competition Ground Plastic Running Track Main Competition Area to ensure the thickness of the error control for the positive difference, so the average thickness of more than 14MM.
(3) plastic runway after the rain does not accumulate water construction experience: A, in order to ensure smoothness, paving span as large as possible, the main runway on the span of 3.66 meters (three road paving at the same time), non-competitive area span greater than 4 m. B, generally in the north and south semi-circle after the rain is sure to have a partial accumulation of water phenomenon, especially in the high jump area of the semi-circle is more serious. In order to ensure the slope, it is best to use the "turtleback" construction method, in order to facilitate drainage.
(4) to prevent the rubber surface after paving local blistering shell, for the grass-roots level of compactness should be strictly controlled to prevent the asphalt base layer of its own embedded extrusion is not solid, shelling delamination, resulting in poor adhesion, surface vaporization, the rubber surface is pulled off. Grass-roots compactness is not enough places, you can use the drill hole, filling rubber (rubber nails) method of reinforcement.
(5) In order to ensure the flatness and slope, after the mold strip is nailed, use the level meter to simulate the correction, the grass-roots level of individual high places, the first to be leveled, individual low places, fill in the level with glue.
(6) The base area contaminated and corroded by diesel fuel is firmly dug out and filled with glue.

Plastic runway paving - Maintenance and care of the back layer of plastic runway paving
(1) Plastic running track, suitable for ordinary short spiked sports shoes (spikes length ≤ 6mm), training shoes, rubber canvas shoes or soft rubber shoes. Plastic running track is only used for training and competition activities, and must not be used for other purposes.
(2) All vehicles are prohibited on the plastic runway, and the runway avoids violent mechanical impact and friction.
(3) The edge of the plastic runway should be protected, shall not be arbitrarily stripped, such as found damaged should be repaired in a timely manner.
(4) Avoid contact with organic solvents and chemicals.
(5) Keep clean, can be rinsed with water, sticky oil available 10% ammonia or detergent scrub clean.
(6) Distribute personnel evenly across the track during training to avoid uneven use of the field.
(7) Smoking littering of cigarette butts, chewing gum or sugary drinks is prohibited.

Plastic track laying - Plastic field standard
Some testing standards and measurement basis for plastic runway
Implemented on 1994-10-01
1. Thematic content and scope of application
This standard specifies the technical requirements of plastic running track, test methods, inspection rules, use and maintenance.
This standard applies to polyurethane as the main material of mixed elastomer paved sports stadiums and halls runway.
2. Definitions
Plastic track refers to the synthetic material elastomer with rubber-plastic properties of the paved surface of the field for track and field competition.
