A rheological study on rejuvenated binder containing very high content of aged bitumen [PDF]

, 2018
Hot recycling of reclaimed asphalt pavement (RAP) coming from flexible pavement rehabilitation is a technique able to ensure real economic and environmental benefits related to the reduction of virgin bitumen and aggregate supply and to the reuse of a ...

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 ...

Valorization of petroleum sludge as rejuvenator for recycled asphalt binder and mixture

Case Studies in Construction Materials
The production of new pavements involving recycled asphalt pavement (RAP) is beneficial for preserving petroleum asphalt and natural aggregates. However, increasing the RAP content raises performance concerns in new pavement, thus necessitating the use ...

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 ...

Multi‐Parameter Investigation of Cretaceous to Palaeocene Sedimentary Sequences in the Anambra and Niger Delta Basins, Nigeria: Organic Matter Characterisation, Palynofacies and Implications for Palaeoclimate and Sea‐Level Changes

Geological Journal, Volume 60, Issue 1, Page 196-222, January 2025.
The study examines Cretaceous to Palaeogene sedimentary sequences in the Anambra Basin, part of West African rift basins, utilising geochemical and palynological interpretations to understand organic matter accumulation. Palynofacies and geochemical data indicate a predominantly warm and humid tropical climate during a time of widespread marine ...

Evaluation of Waste Bottle Crates in the Form of Pyro-Oil and Fine Granules as Bitumen Rejuvenators and Modifiers

, 2023
This research study aims to investigate the feasibility of incorporating high-density polyethylene waste (HDPEW) into bitumen applications. Two conventional conditions of bitumen, namely, aged bitumen (AB) and virgin bitumen (VB), are rejuvenated and ...

Effects of SBS and Polyester Fiber on Performance Characteristics of Hot Recycled Asphalt Mixtures With High RAP Content

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
The decrease in the viscoelasticity of the binder and the failure of the aggregate gradation are the main reasons for the poor crack resistance and stability of hot recycled asphalt mixtures with high reclaimed asphalt pavement (RAP) materials content.

Geochemical and microbiological variability of aerobic and anaerobic sediments along a bifurcated sulphate‐saturated brine spring in western Canada

The Depositional Record, Volume 10, Issue 5, Page 637-669, November 2024.
A tufa mound developed in north‐east Alberta is characterised by an unusual emplacement of a gypsum caprock. This two‐tiered architecture resulted from the bicarbonate‐saturated groundwater flow along Upper Devonian limestone being redirected deeper and encountering the halite–anhydrite dissolution trend within the underlying Prairie Evaporite ...
