Evaluation systems for service performance of subgrade engineering in permafrost regions

Journal of Infrastructure Preservation and Resilience
The quantitative evaluation of subgrade service performance is one of the key challenges for road construction in cold regions, and is essential to selection and decision of subgrade structure. Based on relevant specifications and literatures, this paper

Effects of u-shaped subgrade concrete panel on subgrade deformation

IOP Conference Series: Materials Science and Engineering, 2019
Abstract California Bearing Ratio of subgrade lesser than 5% requires a treatment work either by stabilisation or strengthening method. In this study, the latter concept was chosen for the application of U-shaped Subgrade Concrete Panel as it is a method that has less disturbance to the native soil.

Relationship Between Microstructure and Long‐Term Strength of Compacted Q2 Loess Under High Confining Pressure

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The microstructure of compacted loess exerts a substantial influence on its long‐term strength. Gaining a comprehensive understanding of the law governing how microstructural changes affect its long‐term strength is conducive to guiding the construction of high‐fill loess projects.

Natural Gradient Boosting for Probabilistic Prediction of Soaked CBR Values Using an Explainable Artificial Intelligence Approach

Buildings
The California bearing ratio (CBR) value of subgrade is the most used parameter for dimensioning flexible and rigid pavements. The test for determining the CBR value is typically conducted under soaked conditions and is costly, labour-intensive, and time-

A Bio-Wicking System to Prevent Frost Heave in Alaskan Pavements: Phase II Implementation [PDF]

, 2019
Water within pavement layers is the major cause of pavement deterioration. High water content results in significant reduction in soil’s resilient behavior and an increase in permanent deformation.

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.

Gradient Boosting‐Based Modeling of Structural Performance in Hybrid Multi‐Tube Columns

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study presents an advanced predictive framework for estimating the ultimate confined strength (fcc,u) and ultimate strain (εcc,u) of a hybrid multi‐tube concrete column (MTCC), an innovative structural system that combines a fiber‐reinforced polymer (FRP) outer tube, inner steel tubes, and void‐filled concrete.
