Laboratory investigation of geopolymer stabilized subgrade soil reinforced with Alkaline binder-coated Natural Jute Sheet [PDF]

E3S Web of Conferences
Soft subgrade soils often pose significant challenges in pavement design due to their low bearing capacity and high compressibility, and poor durability under repeated loading.

Improving Weak Subgrade Soil Using Different Additives

Materials, 2022
Weak subgrade is the main problem facing most highway projects. Therefore, this study focuses on trying to improve the properties and increase the strength of weak, clayey, swelling soil for use as a subgrade for pavement structural sections. This trial was developed using a mix of granular and chemical stabilization for the soil.

Field‐Validated Predictive Model for Strain Modulus of Dispersive Clay Stabilized With a Waste Calcium Composite for Sustainable Subgrade Design

Engineering Reports, Volume 8, Issue 7, July 2026.
A field‐validated predictive model accurately estimates the strain modulus of waste calcium composite‐stabilized dispersive clay. The model provides a reliable, sustainable, and cost‐effective tool for subgrade design, reducing dependence on extensive field testing while improving pavement performance.

Investigation of Water and Soil Migration and Mud Pumping of Subgrades under Traffic Load

Atmosphere, 2023
Atmospheric precipitation leads to the increase of moisture in the subgrade. The moisture and soil migration in subgrade is a key scientific problem in evaluating the service performance of the subgrade and resolving or preventing mud pumping.

Economic Potential of Reusing Construction and Demolition Waste (CDW) as Aggregates in Retrofit Projects

Environmental Quality Management, Volume 36, Issue 1, July 2026.
ABSTRACT This study investigates the technical and economic feasibility of reusing Class A Construction and Demolition Waste (CDW) in urban retrofit projects in Recife, Pernambuco. The research focuses on the production of recycled aggregates for soil stabilization in foundations, a geotechnical application seldom explored in retrofit contexts.

Sudan Subgrade Soils Characteristics

IOSR Journal of Engineering, 2014
In this paper, Sudan climate and geographic features have been covered. Then a soil survey for Sudan soil types has been carried out. The locations of soil samples have been chosen in accordance with the Climatic Zones Classifications for Sudan. Two basic tests conducted comprising: Grain Size Distribution and Atterberg Limits on each sample.

Intensifying Climate Extremes Over the Tibetan Plateau: Past–Future Changes and Implications for Railway Infrastructure

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Climate extremes over the Tibetan Plateau (TP) are intensifying and can threaten high‐altitude railways by altering permafrost stability, freeze–thaw regimes, drainage pressure, and hydro‐geomorphic hazards, yet their evolution for railways remains insufficiently quantified. Using CN05.1 observations (1961–2022) and an evaluated NEX‐GDDP‐CMIP6
