Exploring the unjamming transition of meso‐mechanical shear failure behavior in asphalt mixture

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 27, Page 4929-4945, 14 November 2025.
Abstract Asphalt pavement is widely used in transportation systems due to its superior comfort, rapid construction, and convenient maintenance, while also being confronted with the problem of shear failure damage. Herein, two‐dimensional virtual models of asphalt mixture specimens are constructed based on the discrete element method for the virtual ...

Field Sampling and Laboratory Preparation of Hot Mix Asphalt (HMA) With Admixture: Insights From Erbil Roads

Journal of Engineering, Volume 2025, Issue 1, 2025.
Asphalt cement, often referred to as asphalt or bitumen, is a fundamental material used in the production of hot mix asphalt (HMA) for road pavements. Historically, asphalt was combined directly with other materials to create conventional HMA without any form of modification.

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
