Rejuvenation of aged asphalt binder extracted from reclaimed asphalt pavement using waste vegetable and engine oils

Case Studies in Construction Materials, 2019
After many years in service, bituminous material in roads becomes aged and starts losing its properties. Aged bitumen becomes more brittle and causes a reduction in pavement strength with a decrease in the service life of pavement.

Recycling of Polymer Components From Waste Face Masks for Asphalt Modification: A Mini Review

Journal of Applied Polymer Science, Volume 143, Issue 2, January 10, 2026.
ABSTRACT The COVID‐19 pandemic greatly increased plastic waste through widespread personal protective equipment (PPE) use, creating a serious environmental challenge. Disposable face masks (FM), primarily composed of non‐biodegradable polypropylene, account for an estimated 86 million units discarded monthly, leading to significant environmental ...

Rheo‐Chemical Characterization and ML‐Based Prediction of Rejuvenated RAP Binders

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Reclaimed asphalt pavement (RAP) has gained significant attention in pavement engineering due to its economic and environmental benefits. However, the high stiffness and brittleness of aged RAP binders (RPB) necessitate the use of rejuvenators to restore their performance. This study evaluated the effectiveness of two commercial rejuvenators (PX and RB)

Contributions of arid climate and hydrothermal fluid flow on sedimentation in saline‐alkaline lakes: Insight from the Ibar intramontane basin (Southern Serbia)

The Depositional Record, Volume 11, Issue 4, Page 1029-1062, September 2025.
The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...
