Analysis of bitumen ageing processes and innovative techniques for the rejuvenation
International Conference on Road and Rail Infrastructure, 2018Bitumen (asphalt) oxidative aging is one of the prevalent causes of the pavement distresses which results asphalt pavement susceptibility to fatigue and low temperature cracking. Ultimately, aging of asphalt leads to pavement failure after years of usage. Environmental and financial issues raise demand of effective pavement materials recycling. However,

Rheological Modelling of the Bitumen from Reclaimed Asphalt with Rejuvenation and Re-ageing
2021Hot recycling of reclaimed asphalt (RA) in new asphalt concrete (AC) allows achieving large environmental and economic benefits. However, the aged bitumen in RA has a stiff and brittle behaviour, which may lead the AC to premature fatigue, thermal and reflection cracking.

A new approach for evaluating rejuvenator diffusing into aged bitumen
Journal of Wuhan University of Technology-Mater. Sci. Ed., 2011Rejuvenator diffusing into aged bitumen was evaluated by determining penetration and chemical components of aged bitumen with rejuvenator coat before and after diffusing experiment. Effects of temperature, time and viscosity of rejuvenator on the diffusing ability of rejuvenator into aged bitumen were investigated.

The current commercially available rejuvenators are designed mostly for base bitumen and not suitable for the recycling of PMA. For this reason, this research aims at designing an innovative rejuvenator specifically for the recycling of PMA. Firstly, a series of performance-based test methods, including viscoelastic properties, rutting resistance ...
