Stabilization of Clay Subgrade Soil by Using Waste Foundry Sand with a Geogrid

CivilEng
Various stabilizers, such as jute, gypsum, rice-husk ash, fly ash, cement, lime, and discarded rubber tires, are commonly used to improve the shear strength and overall characteristics of clay subgrade soil.

Influence of Subgrade and Unbound Granular Layers Stiffness on Fatigue Life of Hot Mix Asphalts - HMA

TecnoLógicas, 2013
The mainly factors studied to predict fatigue life of hot mix asphalt-HMA in flexible pavements are the loading effect, type of test, compaction methods, design parameters of HMA (e.g., particle size and size distribution curve, fine content, type of ...

Geogrid-stabilized eco-friendly aggregates for pavement base – quantitative assessment using Bender Element sensor technology [PDF]

E3S Web of Conferences
Geogrids provide mechanical stabilization by effectively restraining aggregate movements in a granular layer which in turn improve pavement performance and extend its lifespan.

Neural network-based model for prediction of permanent deformation of unbound granular materials

Journal of Rock Mechanics and Geotechnical Engineering, 2019
Several available mechanistic-empirical pavement design methods fail to include predictive model for permanent deformation (PD) of unbound granular materials (UGMs), which make these methods more conservative.

The Influence of Fines Content on the Mechanical Properties of Aggregate Subbase Course Material for Highway Construction using Repeated Load CBR Test

مجلة النهرين للعلوم الهندسية, 2017
The effect of fines content (material finer than 0.075 mm) on the mechanical properties of subbase course aggregate is studied in this paper. a laboratory tests were carried out using percentage of fines material 5%, 10% and 15% by weight adding to the ...

Laboratory-to-field geotechnical suitability assessment of granular lateritic materials-crushed rock aggregate mixture for tropical pavements

Discover Civil Engineering
Granular lateritic materials (GLM), widely used in tropical regions for their availability and low cost, often exhibit high variability and inadequate bearing capacity to satisfy pavement design requirements.

Numerical approach to moisture prediction in thin sealed pavements under rainfall influence

Results in Engineering
Rainfall is a primary driver of moisture ingress in unbound granular pavements, especially those surfaced with thin sprayed seals. In high-rainfall regions, moisture accumulation can compromise pavement integrity, leading to structural weakening and long-
