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 ...

Recent Advances in Soil Stabilization and Reinforcement: A Comprehensive Review of Emerging Technologies

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The rapid increase in the global population has intensified the need for residential areas and civil infrastructure, ultimately leading to construction in areas with less desirable geological conditions. This underscores the necessity for soil improvement. With increasing public concern for environmental issues and the urgent goal of achieving net‐zero

Mechanism and Modeling of Strength Loss for Saline Aeolian Sand: A Deterioration Framework Under Freeze‐Thaw Cycles

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
In desert edge areas, the degree of soil salinization is high, and aeolian sand contains a significant amount of fines. As fine‐grained aeolian sand is more susceptible to temperature, moisture, and salt influences compared to pure aeolian sand, its use in road construction may induce roadbed diseases at later stages.
