Effect of ageing process on bitumen and rejuvenated bitumen

Construction and Building Materials, 2017
Abstract In the last few decades, highway agencies and the paving companies have invested huge efforts on increasing the amount of reclaimed asphalt (RA) to be introduced in the production of new asphalt concrete (AC). This technique, so-called hot recycling of RA, offers several economical and environmental advantages tightly related to the ...

Full range temperature susceptibility of aged bitumen rejuvenated by polymer modified bio-derived rejuvenator

Materials and Structures/Materiaux Et Constructions, 2021
In this work, a polymer modified bio-derived rejuvenator consisting of bio-oil, polymer modifier, and other additives (plasticizer, cross-linking agent) was developed. Commercial rejuvenator (CR), bio-based rejuvenator (BR), and polymer modified bio-derived rejuvenator (PMBR) were applied to rejuvenate the aged base bitumen and styrene–butadiene ...

Ageing of rejuvenated bitumen in hot recycled bituminous mixtures: influence of bitumen origin and additive type

Road Materials and Pavement Design, 2019
The present study aims at investigating the evolution of the rheological properties of a primary bitumen with ageing (first service life), hot recycling (50/50 blending of virgin and aged bitumen, ...
