The establishment of relationships between the shear wave velocity (V s ) and other geotechnical parameters rockfills under large strains (e.g., oedometer-constrained modulus, M oedo , tangent elastic E t is a significant step toward precise modeling earth structure stress–strain behavior. In this study, four specimens reconstituted from rockfill used for Romaine-2 dam construction were investi...

The compression index obtained from an oedometer test is often used to estimate the settlements of clayey subsoil, but compressibility parameters are rarely available during preliminary geotechnical design phase. Various empirical correlations linking other properties such as water content have been proposed. However, Scandinavian clays soft and exhibit greater compressibility, existing transfo...

This study aims to use the crushed glass obtained from waste flasks improve properties of weak roadbed soil. The included crushing and powdering flasks. Afterward, was sieved separated into three classes depending on particle size: class A contains particles with diameter less than 4.75 mm more 1.18 mm, B 0.08 C mm. For each these classes, 6 different contents were mixed a soil their influences...

This investigation discusses the findings on analysis results of a pavement structure constructed on a relatively expansive material consisting mainly of brown clayey silt in Tebessa, Algeria. Cores were brought to the laboratory from a piece of roadwork. Remolded samples were taken from subgrade of a deteriorated road. The soils were generally found to be of medium plasticity and of a medium t...

This study was conducted to investigate the potential benefits of using geogrids in mitigating pavement defects notably roughness and longitudinal cracking on pavements built over expansive soils. The seasonal changes soils (periodic wetting drying) cause detrimental effects overlying road pavements. Such behavior simulated a controlled laboratory environment through allowing cyclic drying an s...

The mechanical integrity of caprocks overlying injection formations is one the key factors for safe storage carbon dioxide in geological formations. Undrained effects caused by CO2 on strength and elastic parameters should be properly considered operational design to avoid fracture creation, fault reactivation unwanted surface uplift. This study presents results from eleven undrained triaxial c...

compressibility characteristics of fine-grained soils are often the most important parameters for settlement evaluation of the founded layers. the compression index which is the slope of virgin curve is usually for determination of settlement potential of fine grained soils. in this research, the effects of different physical and index properties of soil samples were investigated on compression...
