State of the Practice − Sub‐Aqueous In‐Situ Solidification for Contaminated Sediment Remediation

Remediation Journal, Volume 36, Issue 4, Autumn 2026.
ABSTRACT In‐situ solidification (ISS) has emerged as a cost‐effective and versatile technology for sediment remediation, particularly for addressing contamination at greater sediment depths. This paper evaluates ISS in the context of conventional sediment remediation approaches, highlighting its advantages, design and implementation considerations, and

Developing Correlation Relationship between Modulus of Subgrade Reaction and Resilient Modulus for Florida Subgrade Soils

, 2011
The resilient modulus of pavement subgrade is an essential parameter for mechanistically based pavement design procedures; the modulus of subgrade reaction (k) is used as a primary parameter for rigid pavement design.

Mix Proportion of Fly Ash Concrete Based on the Strength Contribution Ratio

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
ABSTRACT This study aims to expand the use of fly ash concrete (FAC). Based on an experimental investigation of k values or the contribution of FA addition to the strength of ordinary Portland cement or Portland blast‐furnace slag cement type B, we propose and validate an environmentally friendly mix design for FAC.

Photovoltaic‐Assisted Energy Optimization for High‐Speed Train Performance in South Africa Intercity Electric Rail Corridors

The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
ABSTRACT Decarbonizing the intercity rail in sub‐Saharan Africa requires the use of energy architectures that go beyond traditional grid reliance at the expense of traction performance. This paper introduces a novel photovoltaic (PV)‐assisted hybrid traction topology for a 42 km Pretoria–Sandton rail corridor in South Africa, where between‐rail PV ...

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

Application of FWD and GPR for Performance Evaluation of In‐Service Roads

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Road performance detection typically encompasses structural strength testing and damage assessment, with the resilient modulus serving as a key indicator of structural integrity. To enhance the assessment of road performance, this study explores the combined application of falling weight deflectometer (FWD) and ground penetrating radar (GPR) in ...
