通过对沥青混合料铺面温度分布均匀性的研究,比较了红外摄像技术与玻璃温度计技术采集性能的差异,并提出了采用红外摄像技术的优越性,进一步阐述了摊铺机螺旋布料器温度分布不均匀性、沥青混合料摊铺薄弱环节温度离析的差异性,以及外界环境对温度衰减的规律性。最后,优化了基于温度分布的均匀性评价方法与判定标准。 Through the research on the uniformity of temperature distribution of asphalt pavement, the differences between infrared camera technology and glass thermometer acquisition performance were compared. The superiority of infrared camera technology was put forward. The temperature distribution of paver spiral distributor was further described. Uniformity, the difference of temperature segregation in the asphalt paving weakness, and the regularity of the temperature decay in the external environment. Finally, the method and criteria for evaluating the uniformity based on temperature distribution are optimized.
