Sunshine plastic runway criteria: 1 standard runway length is 400 Mi Bosen plastic materials should be two parallel straights and corners two radii are equal composition. Weeding to the runway, the sudden application of the inner runway suitable material to be along the boundary. Ledge high about 5 cm wide and at least 5 cm. 2 runway length shall be measured along the runway protruding beyond the outer edge of 30 cm. If there is no conflict should be measured along a line outside the outer edge of 20 cm mark. Note: "IAAF Track and Field Facilities Manual" contains all the relevant runway structure, design, technical information tag. This rule gives the basic principles that should be followed. 3.400 m, and 400 m below the track, each athlete should occupy a lane, lane width of a minimum of 1.22 meters sunshine plastic runway, up to 1.25 m supply plastic track, lane width of 5 cm, all lanes should be wide same. The provisions of paragraph 2 shall be the measurement of the length of the first lane, the other lane length shall be measured at 20 cm beyond the outer edge of the inside lane line. Printing type slip plastic track first need to be waterproof cement or asphalt foundation basis for back treatment. Base layer can be dealt with the underlying maintenance paving the runway after 24 hours, with a plastic substrate doped with 25% according to national standard 3-4mm diameter high elastic black rubber, stir into the venue, scraping rake Calibrating supply quality plastic track laying thickness of 10mm, curing and maintenance 24 hours. FT into the runway surface 2.5mm thick printing material, scraping rake Calibrating die above the cover with the printing material, printing die off after 24 hours, 2-3mm thick to see the printing surface. Supply of plastic track, sunshine plastic runway, building supply Berson Berson materials provided by plastic track.
