Experimental Characterization and Numerical Performance Assessment of Treated Cinder Gravel for Base Course Applications

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study investigated the suitability of natural cinder gravel blended with fine‐crushed aggregates as a base course pavement material using laboratory tests and numerical simulations. Laboratory test results for natural cinder gravel indicated that cinder gravel alone failed to meet the Ethiopian Roads Authority (ERA) standard specifications for ...

Three‐dimensional reconstruction of loose defects in semi‐rigid base layers using enhanced deep learning and point cloud from GPR images

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 31, Page 6475-6492, 29 December 2025.
Abstract Loose defects in semi‐rigid base layers can critically compromise the structural performance and long‐term serviceability of asphalt pavements. However, accurate identification and quantitative assessment of such defects remain challenging due to the lack of reliable ground‐penetrating radar (GPR) data sets and the limitations of existing ...

Fracture and Damage Analysis of Cement‐Stabilized Fine and Coarse Grain Soils Under Static and Cyclic Loading Using Chevron‐Notched SCB Specimen

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 6, Page 2708-2724, June 2025.
ABSTRACT Fracture toughness and cohesive fracturing properties of two classes of sandy‐clay soils, (A) with fine and (B) coarse grains and stabilized with low (2%) and high (10%) cement (as soil stabilizer), were investigated using a chevron‐notched semicircular bend (CN‐SCB) sample under static and cyclic loads.

Study on Mechanical Properties of Gold Mine Tailings Stabilized by Composite Alkali‐Activated Materials

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Gold mine tailings (GMTs) pose significant environmental challenges, and while alkali‐activated materials (AAMs) have been widely used as sustainable alternatives to Portland cement for stabilizing geotechnical materials, further research is needed to optimize their composition and performance, particularly by incorporating traditional industrial waste
