Comparison of technical and short-term environmental characteristics of weathered and fresh blast furnace slag aggregates for road base applications in South Africa

Case Studies in Construction Materials, 2019
This study investigated chemical, physical-mechanical and environmental characteristics of weathered blast furnace slag (WBFS) and freshly produced slag (FBFS) for their potential utilisation as granular road base and subbase aggregates.

Evaluation of pavement design input parameters of biaxial and triaxial geogrid stabilized flexible pavements overlying soft subgrades

Cleaner Materials, 2023
Stabilization of flexible pavement layers using geogrids to improve the mechanical response of pavement layers is gaining importance over conventional stabilization techniques due to their low cost and superior performance.

Jointed Plain Concrete Pavements in Airports: Structural–Economic Evaluation and Proposal for a Catalogue

Infrastructures, 2021
Although the design of jointed plain concrete pavements could be solved by commercial software, there is still a need for simple tools to be used in feasibility studies and preliminary cost–benefit analyses. This paper analyzed and verified jointed plain

Medium-size triaxial apparatus for unsaturated granular subbase course materials

Soils and Foundations, 2014
AbstractThis paper proposes a testing method for evaluating the effect of water content on the deformation–strength characteristics of unsaturated subbase course materials. A medium-size triaxial apparatus for unsaturated soils is newly developed in order to examine the mechanical behavior of unsaturated subbase course materials subjected to ...

Large scale trial evaluation of granular layers reinforced with geocells [PDF]

E3S Web of Conferences
Geocells are three-dimensional geosynthetics made up of interconnected cells that confine the granular materials embedded in them. This confinement generates an increase in the rigidity and a decrease in the deformability of the reinforced layer ...

Scalable Electrochemical Concrete Fabrication and Closed‐Loop Recycling

Advanced Science, Volume 13, Issue 24, 27 April 2026.
The electrochemical‐driven recycling strategy establishes a reversible concrete material flow by extracting Ca, Si, Al, and Fe from concrete waste and regenerating functional feedstocks. These reversed products are reassembled into new concrete, which re‐enters service and ultimately returns to waste, enabling a closed‐loop, waste‐origin, and low ...

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
