Bitumen, a vital component in asphalt mixtures for road construction, confronts persistent
challenges stemming from traffic loads and temperature fluctuations, leading to issues such …

Prompting high content of reclaimed asphalt pavement (RAP) to be used in road building
and maintenance has drawn great attention. The application of rejuvenators is an efficient …

This study examines the merits of esterification of waste cooking oil to reduce its acidic
content for use as a rejuvenator for aged asphalt. It further examines how acidic compounds …

Due to the poor cracking performance of aged binders, the use of reclaimed asphalt
pavement (RAP) in road pavements is limited. When applying a greater RAP percentage …

The bio-oil, with environmental friendliness and good compatibility with asphalt, has been
widely used in rejuvenating aged asphalt. In this study, based on the ability of bio-oils to …

Incorporation of rejuvenators can promote the rejuvenation of heavily oxidized asphalt when
high proportion of reclaimed asphalt pavement (RAP) is used. However, there are few …

The construction of new buildings and infrastructural projects across the globe poses
numerous challenges in terms of material extraction, availability of resources, disposal of …

The asphalt mixture is easily affected by water erosion with different solutes. The molecular
dynamics (MD) simulation method was adopted to explore the influence of solute on the …

Under the influence of complex environments and increasing traffic loads, asphalt
pavements expose early failure due to the dependence of asphalt on temperature and …

To develop a new sustainable compound bio-oil rejuvenator product and understand its
rejuvenation mechanism on long-term aged asphalt, the castor oil vegetable asphalt (COA) …
