使用三维成像系统——伊利诺伊大学集料图像分析仪(UIAIA),根据已建立的UIAIA试验方法,由粗集料颗粒图像分别定义出集料基于成像技术的三维形状、尺寸、棱角性和表面构造指数。应用统计学方法,结合图像分析确定了4类常用的粗集料形状特性数据。指出了粗集料基于成像的棱角性和表面构造指数之间存在的确定性关系,并且将它们联系到实验室和现场沥青混合料的使用性能。 Using UIAIA, a three-dimensional imaging system based on UIAIA, the three-dimensional shape, size, angularity and surface texture of aggregates based on imaging technology were defined respectively from coarse aggregate particle images index. Using statistical methods, combined with image analysis to determine the four kinds of commonly used coarse aggregate shape characteristics of data. It is pointed out that there is a deterministic relationship between the coarse aggregate based on the angularity of the image and the surface texture index and relates them to the performance of laboratory and field asphalt mixtures.
