| The main objective of this research was to evaluate the Recycled Asphalt Pavements materials. The Recycled Asphalt Pavements materials used in the laboratory were collected from expressways and urban roads in Heilongjiang province. The aggregates and asphalt binders were extracted from Recycled Asphalt Pavements materials, and tested in the laboratory including aggregate graduation and binder properties. Also, the changes of materials properties after using were compared and discussed, and the variability of asphalt binder was analyzed. Then, the properties differences between different materials were compared. The design and performance evaluation of recycled asphalt mixture were implemented. Finally, some preliminary conclusions and recommendations for the future research were proposed. |
