| 摘要： | A procedure combining Micro-Deval and 2nd generation Aggregate Imaging Measurement System (AIMS-II) test procedures was developed to characterize aggregate polishing characteristics, and in turn, provide a means for qualifying aggregate sources for friction purposes. This study focused on the minimum number of aggregate particles, aggregate sizes, and the number of revolutions in the Micro-Deval test. Only two aggregate sources were included in this study. Thus, further analyses are needed for wider range of aggregate sources/mineralogical properties in order to establish the minimum required aggregate shape properties for friction. |
