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...

Data acquired from the hyperspectral airborne sensor DAIS-7915 over Antequera in southern Spain was processed to yield a quantitative soil swelling potential map based on three physicochemical soil properties currently used in engineering as measures of soil swelling namely cation exchange capacity (CEC), coefficient of linear extensibility (COLE), and Saturated moisture content (SP). The metho...

Microbially induced calcite precipitation (MICP) has been a promising method to improve geotechnical engineering properties; however, there are few literatures about the application of MICP strength characteristics expansive soils with low permeability. In this paper, series CD triaxial tests were carried out investigate effect on soils. The results show that shear specimens increased increase ...

Background: Geotechnical engineers working on the ground face a common obstacle of unsuitable soil. Expansive soil is one soils vulnerable to high loads and unstable. Properties such as permeability, low bearing capacity, compression, swelling shrinkage behavior, strength stiffness are all characteristics an expanding weaker than other types due these characteristics. Objective: T...

Extension of the effective stress concept to unsaturated soils has been a major concern for decades. Recent studies significantly contributed understanding fundamentals behind Bishop's parameter χ, which is generally used define soils. An examination recently proposed methods showed that contribution suction was often overestimated, especially in high range. In this study, considering soil pore...
