Review of ultraviolet ageing mechanisms and anti-ageing methods for asphalt binders
Journal of Road Engineering, 2022 Summary: Asphalt binder is inevitably aged by ultraviolet (UV) light during its service period. UV ageing can significantly decrease the technical properties of asphalt binder. The sensitivity of asphalt to UV ageing and thermal-oxidative ageing differs,

Reversible Aging in Asphalt Binders [PDF]
Energy & Fuels, 2007 X-ray diffraction, optical microscopy, and mass spectrometry techniques were used in an attempt to clarify the morphological and chemical features that are responsible for reversible aging processes that occur in asphalt binders during conditioning at low temperatures. The reversible aging term is used in this paper to capture all reversible processes (

Engineered nanocomposites in asphalt binders
Nanotechnology Reviews, 2022 Abstract Recently, nanotechnology has been effectively used in the field of road pavement. Oxidation and aging of asphalt cause deterioration of road pavements and increase asphalt-related emissions. We propose an anti-aging strategy to interrupt the asphalt deterioration by using engineered clay/fumed silica nanocomposites.

Moisture susceptibility of high and low compaction dry process crumb rubber modified asphalt mixtures [PDF]
, 2010 The field performance of dry process crumb rubber-modified (CRM) asphalt mixtures has been reported to be inconsistent with stripping and premature cracking on the surfacing. One of the concerns is that, because achieving field compaction of CRM material

Binder design of high RAP content hot and warm asphalt mixture wearing courses [PDF]
, 2015 Reclaimed Asphalt Pavement (RAP) has shown great potential for being used in the construction or maintenance of roads. However, RAP is usually downgraded to lower pavement layers and the percentage of RAP used in wearing courses is still moderate (≤30%).

Characterisation of colloidal nanosilica modified asphalt binder [PDF]
, 2021 Nanosilica (NS) has been used in this study as an asphalt binder modifier to improve the binder properties. Penetration grade 60/70 (PEN 60/70) asphalt binder was modified with NS in colloidal form with an average size of 10 to 15 nanometer (nm).

Rutting Characteristics of Bio-Asphalt Binder Based on the Multiple Stress Creep Recovery Test Results [PDF]
Journal of Rehabilitation in Civil EngineeringThe phenomenon of asphalt binder aging can lead to various failures, such as rutting in the asphalt mixture. Rejuvenator materials are used to mitigate asphalt binder aging. Bio-asphalt, as a binder modified with bio-waste materials, offers environmental
