Influence of Polymer and Rubber Modification on Fatigue Crack Propagation in Asphalt Mixtures: A Cyclic SCB and Paris Law Investigation

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 11, Page 5099-5116, November 2026.
ABSTRACT Fatigue cracking is a major distress limiting asphalt pavement service life, and Paris law–based fracture mechanics offers a more mechanistic understanding than conventional fatigue testing. However, systematic characterization across diverse modifiers, dosages, notch depths, and temperatures remains limited.

Machine Learning Approaches for Predicting Total Organic Carbon From Petrophysical Well Logs in the Wufeng–Longmaxi Shale, Southeast Sichuan Basin, China

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
This study demonstrates the application of machine learning models—Random Forest, XGBoost, and Multiple Linear Regression—to predict Total Organic Carbon (TOC) from well logs, significantly improving TOC prediction accuracy and reliability across diverse geological settings compared to traditional log‐based methods.

The UK Clean Air Act at 70: An interdisciplinary analysis of historical air quality change

Weather, Volume 81, Issue 10, Page 316-322, October 2026.
2026 marks the 70th anniversary of the first UK Clean Air Act, a pivotal moment for air quality in modern British history. Previous narratives on this legislation have largely centred on pollution in London and monodisciplinary perspectives. This article integrates historical research with reconstructed estimates of PM2.5 concentrations to spotlight ...

Effects of nano eggshell powder as a sustainable bio-filler on the physical, rheological, and microstructure properties of bitumen

Results in Engineering
Improving bitumen properties to withstand traffic loads and environmental conditions is essential for prolonging pavement life. Given that nanomaterials stand as potential candidates to fulfil these requirements, this study focused on the potential use ...

Seismic Versus Sub‐Seismic Experimental Mirror‐Like Fault Surfaces in Bituminous Dolostones

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Mirror‐like Surfaces (MSs) are ultra‐polished surfaces frequently found in exhumed seismogenic fault zones in carbonates. They form over a wide range of pressure‐temperature conditions and slip rates, from seismic (≈1 m/s) to sub‐seismic (≈0.1–100 μm/s), reflecting distinct phases of the seismic cycle.

Subsurface Hydrocarbon Biodegradation in the Context of Microbial Habitability and Hydrogeologic, Thermal, and Geologic Evolution of the Colorado Plateau

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Subsurface microbial ecosystems associated with hydrocarbon reservoirs are shaped by temperature, salinity, redox gradients, and fluid flow. However, the drivers of microbial activity and hydrocarbon biodegradation over geologic timescales remain poorly constrained.

Evaluation of rheological and microstructural behavior of modified asphalt binder with chitosan derived from shrimp shell powder

Results in Engineering
Chitosan derived from shrimp shells (SSPCH) was used for the first time as a biological biopolymer to modify the properties of bitumen across high, medium, and low-temperature ranges. Therefore, physical tests (penetration, softening point, and ductility)

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.
