摘　　要：路面工程中集料来源不同导致了集料性质的巨大差异,从而影响集料与沥青的黏附性能,精准评估和区分多源集料与沥青的黏附性能,是保证沥青路面性能的重要前提。该文提出基于旋转瓶试验和图像处理的多源集料与改性沥青的评价方法,该方法将裹附改性沥青的多源集料进行了旋转瓶试验,通过图像处理得到的沥青剥落率来定量评价黏附性能,进而对浸水冲刷时间作用、沥青老化作用等因素的影响情况进行分析。评价结果表明:该方法能明显区分出多源集料黏附性差异,具有一定现实及工程意义。The diversification of aggregate sources in pavement engineering has led to significant differences in aggregate properties,thereby affecting the adhesion performance between aggregates and asphalt.Accurately evaluating and distinguishing the adhesion performance between multi-source aggregates and asphalt are important prerequisites for ensuring the performance of asphalt pavement.A method for evaluating multi-source aggregates and modified asphalt based on rotary bottle tests and image processing was proposed.Rotary bottle tests were conducted on multi-source aggregates coated with modified asphalt,and the adhesion performance was quantitatively evaluated through the asphalt spalling rate obtained from image processing.Furthermore,the influence of factors such as immersion time and asphalt aging was analyzed.The evaluation results indicate that this method can clearly distinguish the differences in adhesion performance of multi-source aggregates,which has certain practical and engineering significance.
