Workability of Hot Mix Asphalt
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.
