The aim of this research was to investigate the behavior of cold recycled materials in bitumen emulsion. Firstly a rheological analysis was conducted to establish the effects of rejuvenant on reclaimed pavement; then a mix design procedure for recycled materials was calibrated. Finally the influence of temperature of compaction was considered. The results obtained showed that: the proposed mix design procedure allows to increase the role of components on the behavior of the mixture; the influence of rejuvenant is related to the temperature and condition of the bitumen; the effects of the increase of temperature are strictly dependent on the percentage of bitumen.

Abstract
The aim of this research was to investigate the behavior of cold recycled materials in bitumen emulsion. Firstly a rheological analysis was conducted to establish the effects of rejuvenant on reclaimed pavement; then a mix design procedure for recycled materials was calibrated. Finally the influence of temperature of compaction was considered. The results obtained showed that: the proposed mix design procedure allows to increase the role of components on the behavior of the mixture; the influence of rejuvenant is related to the temperature and condition of the bitumen; the effects of the increase of temperature are strictly dependent on the percentage of bitumen.| File | Dimensione | Formato | |
