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.

A Sliding Time‐Window Energy Ratio Method for Weak Signal Enhancement of Deep Subgrade Voids in GPR Data

Applied Research, Volume 5, Issue 4, August 2026.
A sliding time‐window energy ratio method is proposed to enhance weak GPR reflections from deep pavement voids. By combining target‐window localization with same‐window normalization, STWER suppresses non‐target interference and improves defect localization, as demonstrated by numerical simulations and field cases verified by excavation and core ...

A review on improving the key engineering properties of lateritic soil by treating industrial by-products and wastes

Case Studies in Construction Materials
Lateritic soils are commonly used in subgrade construction due to their widespread availability in tropical and subtropical regions. However, these soils often necessitate treatment because of their inadequate engineering properties.

Mitigation of potential fat clay subgrade problems utilizing reinforcement and moisture management geosynthetic – a case history [PDF]

E3S Web of Conferences
Pavement construction over expansive soils typically fat clays tend to be expensive because modification or some form of soil improvement needs to be done to render the expansive soils as good and suitable subgrade soils for pavement construction.

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.

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.

Pre-compression and capillarity effect of treated expansive subgrade subjected to compressive and tensile loadings

Case Studies in Construction Materials, 2021
Pavement structures often are under tension and compression mobilised by the coupled effects of traffic loads and swelling stress. Seasonal moisture variations cause capillarity rise and volumetric movement within the subgrade.
