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 ...

Technology and Application of Concrete‐Reinforced Saline Soil Subgrades: A Comprehensive Review

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The high salt content and pronounced water‐salt migration characteristics of saline soils significantly affect subgrade performance. In recent years, concrete reinforcement has become a prevalent technique for enhancing the stability and durability of saline soil subgrades. This article systematically reviews the state of the art in concrete‐reinforced

Deformational characteristics of subgrade soils in Korea

KSCE Journal of Civil Engineering, 2000
Deformational characteristics of subgrade soils are important parameters in the mechanistic design of flexible pavement. The subgrade soils are mostly non-plastic sandy in Korea, and seven representative subgrade soils were collected for testing from the actual pavement projects.

Thermal Stability Analysis and Novel Cooling Technology Field Tests for Permafrost Railway Subgrades

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Global warming has intensified the climatic warming and moistening trend on the Qinghai–Tibet Plateau, threatening the thermal stability of railway subgrades in the plateau permafrost regions. However, previous studies have lacked systematic analyses that comprehensively consider the climate along the railway, permafrost conditions, and subgrade ...

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

Study on the Influence of Loading Frequency on the Bearing Behavior of Pile Groups in Geosynthetic‐Reinforced Pile‐Supported Embankments

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The mechanism of soil arching is a critical technical issue in the load transfer of geosynthetic‐reinforced pile‐supported (GRPS) embankments. To investigate the evolution of soil arching under high‐speed railway loading within a pile group system, a performance analysis model for a GRPS embankment was established using ABAQUS.

Enhancing Expansive Soil Stability Using Agricultural Waste: Soybean Pod Ash and Banana Fiber

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study evaluates the efficacy of agricultural waste—soybean pod ash (SBPA) and banana fiber (BF)—as sustainable stabilizers for expansive soils in Jimma Town, Ethiopia. Soil samples from Kebele 5 and Ajip Kela (1.50 m depth) with the highest plasticity indices and lowest California bearing ratio (CBR) values were selected.
