Mechanism and Performance of Bituminous Mixture Using 100% Content RAP with Bio-Rejuvenated Additive (BRA). [PDF]

Materials (Basel), 2022
The low RAP content, hot mixing conditions, and the addition of a high ratio of new bitumen and aggregates result in low economic and environmental benefits for current regeneration technologies.

Aging and rejuvenation effects on the rheological response and chemical parameters of bitumen

Journal of Materials Research and Technology, 2023
The rejuvenation efficiency of aged bitumen is the main concern when developing rejuvenating agents. It is necessary to develop a method to assess the efficiency of rejuvenators using rheological parameters in the whole frequency region. To this end, the

The role of rejuvenators in embedded damage healing for asphalt pavement

Materials & Design, 2021
Rejuvenator encapsulation technique showed great potential for extrinsic asphalt pavement damage healing. Once the capsules are embedded within asphalt pavement, the healing is activated on-demand via progressing microcrack.

Characterisation of bitumen through multiple ageing-rejuvenation cycles [PDF]

International Journal of Pavement Engineering
The multiple recycling of bitumen offers the possibility of reusing it for repeated lifecycles and achieve a higher degree of circularity of materials used in pavement construction. Aiming to identify the prospect, this study aged bitumen in a laboratory
