How long can the general plastic runway be used normally after the construction is completed?
Several requirements that should be paid attention to in the construction of plastic runway;
In order to ensure the smoothness and slope of polyurethane plastic runway surface and the quality of plastic runway in the future, the quality of asphalt concrete foundation must be accepted before construction, and the acceptance criteria should be implemented according to design standards and technical specifications, and the plastic surface can only be laid after analysis.
The ambient temperature for site paving should be controlled at 5℃ ~ 38℃, so as to avoid operation when the ambient temperature is lower than 5℃ and higher than 38℃. The relative humidity should be controlled below 70%, and the foundation should be smooth and clean. The dosage of catalyst should be adjusted according to the temperature and relative humidity to properly control the curing speed.
When storing color paste and prepolymer, the barrel cover should be tightened, and the water content should be detected before use. After use, the water content in foundation should be controlled to avoid bubbles after gel formation. The quality inspection certificate and validity period of plastic paving materials must be carefully checked when they leave the factory.
