| 摘要： | The term workability has been used to describe several properties related to the construction of hot mix asphalt (HMA). Workability in the field can be defined as a property that describes the ease with which a HMA can be placed, worked by hand, and compacted. This definition provides a term that is applicable to movement of HMA through equipment to the roadway, handwork of HMA, and compactibility on the roadway. The primary objective of this study was to develop a device to measure the workability of HMA mixes that could identify the change in workability due to changes in mix characteristics. Secondly, this study was to evaluate a method in which mix workability could be used for establishing approximate compaction temperatures for HMA mixes. Based on the findings of this study a device was successfully designed to measure the laboratory workability of HMA mixes. |
