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 ...

Bitumen rheology and the impact of rejuvenators

Construction and Building Materials, 2019
Abstract Bitumen is a material used in many industrial applications. It is the primary binding material for road pavements in asphalt. To improve sustainability, it is important to be aware of the finite nature of conventional oil reserves. As a cost and energy saving material, reclaimed asphalt pavement can help preserve our resources. Virgin binder

Rheological properties of aged bitumen rejuvenated by polymer modified bio-derived rejuvenator

Construction and Building Materials, 2021
Abstract In this paper, a polymer modified bio-derived rejuvenator (PMBR) consisting of bio-oil, polymer modifier, and other additives (plasticizer, cross-linking agent) was investigated. The regeneration performance of PMBR on aged base and SBS modified bitumen was compared with that of commercial rejuvenator (CR) and bio-based rejuvenator (BR). The
