摘　　要：集料作为沥青混合料的关键构成部分,其级配的精准控制对沥青路面的路用性能有着极为显著的影响。本研究聚焦基于移动滑块的多阈值数字图像处理技术,深入探究沥青混合料级配监控方法。研究结果表明,相较于普通图像处理方式,该方法在集料颗粒识别精度方面提升约10%,能够在一定程度上缓解在恶劣自然光线条件下集料颗粒图像识别精度欠佳状况。此外,借助级配预估方法,能够对沥青混合料的生产级配进行实时监控,对沥青混合料的生产控制具有应用指导价值。As an essential component of asphalt mixtures,the precise control of aggregate gradation has an extremely significant impact on the performance of asphalt pavements in service.This research focused on the multi-threshold digital image processing technology based on the moving slider and conducted an exploration of the monitoring method for asphalt mixture gradation.It is found that the recognition accuracy of aggregate particles can be improved by about 10% compared with the normal processing technology,which can alleviate the problem of insufficient recognition accuracy of aggregate particles under harsh natural light conditions to a certain extent.At the same time,through the grading estimation method,the gradation of asphalt mixture in mixing period can be monitored in real time,which has practical application value for guiding the production of asphalt mixture.
