红外热像仪与水银玻璃温度计校核一致性良好,使用红外热像仪测温应正确选择拍摄距离、正确设定发射率和环境条件参数。红外热像仪适用于评价松铺沥青混合料的温度均匀性,而不宜用于评价碾压后的沥青混合料。级配离析对温度离析是有影响的,红外热像甚至可反映级配离析的情况。红外热像反映出使用转运车后,即使是全幅摊铺机温度离析也控制得较好,可见转运车减小温度离析的效果超过了摊铺宽度过大的影响。 Thermal imaging camera and mercury glass thermometer calibration consistency, the use of infrared camera temperature measurement should be the correct choice of shooting distance, the correct setting of emissivity and environmental conditions parameters. The thermal imaging camera is suitable for evaluating the temperature uniformity of the asphalt mixture in Songpu and should not be used for evaluating the asphalt mixture after rolling. Gradation segregation is influential on temperature segregation, and infrared thermography can even reflect gradation segregation. Infrared thermography reflects the use of the transfer truck, even if the entire paver temperature segregation is also better controlled, shows the transfer truck to reduce the temperature of the effect of more than the paving width effect.
