Influence of Asphalt Emulsion Stabilization on Pavement Structural Behavior and Life Cycle Assessment (LCA)

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Assessing pavement sustainability requires jointly evaluating structural performance and environmental impacts, yet these dimensions are often analyzed separately. This study proposes an integrated framework combining mechanistic–empirical pavement design and life cycle assessment (LCA) to quantify the structural–environmental trade‐off associated with

Neohypoplasticity for Sand Coupled With the Generalized Intergranular Strain Concept

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 15, Page 3484-3508, 25 October 2025.
ABSTRACT This work presents the coupling of the recently revisited advanced hypoplastic constitutive sand model called neohypoplasticity (NHP) with the more recently introduced concept of the generalized intergranular strain (GIS) to account for soil behavior due to small strains. The latter is essential for the simulation of cyclic deformations.

Friction Characterization and Mitigation in Large‐Scale 6DOF Multi‐Axial Hybrid Simulation

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 9, Page 2283-2302, 25 July 2025.
ABSTRACT In the last few decades, hybrid simulation has become widely used for understanding the response of structural components and systems under extreme loading conditions. Large‐scale, three‐dimensional (3D), multi‐axial testing facilities with six degrees of freedom (6DOF) are versatile testing systems that can be used for testing a variety of ...

Tracking Active Site Formation during Oxidative Activation of Copper‐Exchanged Zeolites for Methane‐to‐Methanol Conversion

Advanced Science, Volume 12, Issue 13, April 3, 2025.
The oxidative generation of Cu(II) active sites in Cu‐exchanged zeolites for the CH4‐to‐CH3OH conversion has been studied. Complementary in situ/operando spectroscopic techniques highlight that the formation rate and the stability of different Cu(II) species are governed by their structure and the zeolite topology.
