Performance of Asphalt Rubber Mixture Overlays to Mitigate Reflective Cracking

open access: yesMaterials, 2022
Adequately predicting overlay behaviour is essential for flexible pavement rehabilitation to reach the predicted lifespan. Reflective cracking is one of the main failure mechanisms affecting overlay performance. This failure may occur due to cracks in the lower layers that propagate to the overlay due to traffic loads, temperature variations, shrinkage

Imaging of vertical surface-breaking cracks in concrete members using ultrasonic shear wave tomography

open access: yesScientific Reports, 2023
Surface-breaking cracks in concrete pose a significant threat to the durability of built structures. They create pathways for an accelerated moisture intrusion, and the transport of environmental and chemical agents such as chloride ions, which in turn ...

Effect of Aggregate Gradation on Reducing Reflection Crack

open access: yesJournal of Engineering and Sustainable Development, 2010
e rehabilitation of cracked flexible pavement roads by overlaying, without any improvement, is rarely a durable solution, as the cracks rapidly propagate through the new asphalt layer.

Penetration Form of Inter-Hole Cracks under Double-Hole Blasting Conditions with Inclined Fissures

open access: yesAdvances in Civil Engineering, 2021
During blasting construction in tunnel engineering, an inclined fissure near the blast hole produces the “Z” type of over-excavation and subsequently affects the overall blasting effect and stability of the tunnel.

Numerical analysis of a testing technique to investigate the dynamic crack propagation in armour ceramic

open access: yesEPJ Web of Conferences, 2018
Ceramic materials are numerically studied to understand their fracturing behaviour upon dynamic conditions and impact loadings. During a ballistic impact of a projectile against a ceramic armour system, an intense fragmentation composed of numerous ...
