In this study, effect of the timestep and thermography method when measuring the surface temperature of the road and surround temperature on pavement watering was verified. The study result showed that the temperature of the surface and surround air were dropped after watering according to the cooling effect, and the temperature change tends to occur considerably within 10 min in this experiment. Therefore the short timestep should be applied according to the site condition to assume the cooling effect of pavement watering. In addition, thermography method showed to be inaccurate right after the watering and when the solar radiation is strong. Therefore, it is necessary to consider the above when using thermography method.

本研究验证了时间步长和热成像方法在测量路面表面温度和周围温度时对路面浇水的影响。研究结果表明，根据冷却效果，浇水后地表和周围空气的温度下降，并且在本实验中，温度变化往往在10分钟内发生较大变化。因此，应根据现场情况采用较短的时间步长，以承担路面浇水的冷却效果。此外，在浇水后和太阳辐射强烈时，热成像方法显示不准确。因此，在使用热成像方法时，需要考虑以上几点。
