(1) In the construction process of polyurethane materials, the most afraid of water.before curing, a drop of water will produce a large bubble, so the constructors in the high temperature conditions to prepare towels to wipe sweat. When laying must grasp the weather conditions and must do to prevent sudden showers of emergency measures. The laid time should avoid the morning atmosphere and the ground when humidity is larger, even in the weather is fine normal working day, begin laid after 9 o 'clock in the morning commonly.

(2) The thickness of plastic is from the bottom to the center of the surface micelles, generally from two aspects of control.Firstly, the thickness and dimension are prechecked by the vertical die, and the local high ground is cut or rammed.If it is not too high, the thickness can be ensured by adding a clamp on the flat scraper to ensure the slurry. The main competition area of the plastic track in the north suburb of the 11th Asian games is to ensure the thickness, and the error control is positive, so the average thickness is more than 14MM.

(3) Construction experience of runway without water accumulation after rain:A. In order to ensure the smoothness, the paving span should be as large as possible. The span of the main track is 3.66 meters (three lanes are paved at the same time), and the span of the non-competition area is more than 4 meters. B. There must be water accumulation in the north and south semicircle after rain, especially in the high jump area.To ensure the slope, the construction method of "turtle back" is adopted to facilitate drainage.　　　

(4) Prevent local foaming and peeling after laying,the density of the base shall be strictly controlled, prevent the base layer of asphalt is not dense, peeling and delamination, resulting in poor adhesion, rubber surface is broken. If local base density is not enough, you can use the drill hole grouting method to strengthen.　　　

(5) In order to ensure the flatness and slope, after the mold is nailed, use the gradienter to conduct simulation correction. even out the high part of the base, and fill in the low part with glue.　　　

(6) Remove the base contaminated and corroded by diesel and fill it with glue.
