| 摘要： | The Colorado Department of Transportation (CDOT) and FHWA's Turner-Fairbank Highway Research Center were selected to demonstrate several pieces of European equipment. The Hamburg wheel-tracking device was one of those pieces of equipment. It is used to predict moisture damage of hot-mix asphalt (HMA). This paper provides an evaluation of factors that influence the results from the Hamburg wheel-tracking device. There was excellent correlation between the Hamburg wheel-tracking device and pavements of known field performance. The Hamburg wheel-tracking device was found to be sensitive to (a) quality of aggregates, (b) asphalt cement stiffness, (c) length of short-term aging, (d) refining process or crude oil source of the asphalt cement, (e) liquid and hydrated lime antistripping treatments, and (f) compaction temperature. The Hamburg wheel-tracking device was demonstrated on two CDOT projects to improve the quality of HMA. |
