Characterizing the Self‐Healing Asphalt Materials: A Neutron Imaging Study

Advanced Engineering Materials, Volume 26, Issue 21, November 2024.
This study breaks new ground using neutron computed tomography to investigate asphalt's self‐healing properties in detail. By distinguishing bitumen from air voids, it shows that 20% sand filler optimizes crack healing, with larger cracks healing more effectively. These findings could transform sustainable road design, enhancing material durability and

Multispectral investigation of natural resins

Archiv der Pharmazie, Volume 357, Issue 11, November 2024.
Natural and processed resins, such as Mumia vera aegyptiaca, have been used as remedies since ancient times. However, analyzing archeological resin samples by established techniques is challenging due to their destructive nature. Five spectroscopic methods were explored for resin identification.

A note on the nonlinear viscoelastic Schapery model applied to PMMA and asphalt

Proceedings in Applied Mathematics and Mechanics, Volume 24, Issue 3, October 2024.
Abstract Viscoelastic phenomena are present in every‐day materials in engineering for example, polymers and bitumen. These materials usually present linear behavior for small deformations and small perturbations from the thermodynamic equilibrium. More generally, nonlinear behaviors may arise due to stress, temperature, ageing, and other drivers.
