Abstract Pavements across Free State in South Africa often experience seasonal moisture
variations that trigger, volumetric movement of the subgrade soil. The interaction of moisture …

Expansive soil is one of the widespread typical problematic soils that poses several
challenges for civil engineers. Expansive soils are hard and strong when they dry out; swell …

Flexible pavement failure has been a major problem encountered in various countries.
Some common distress which had been listed are cracking and rutting. The causes of this …

Clayey soils are considered as problematic soils for geotechnical engineering. They are
characterized by poor geotechnical properties because of their high plasticity and water …

Unsaturated swelling soil behaviour is governed by the matric suction, thus the
predetermination of swelling stress for expansive unsaturated soil requires rigorous …

The expansive soil under investigation has caused damage to lightweight structures due to
its swelling and shrinkage characteristics in response to changing moisture content. The …

Generally, expansive soils undergoes significant volumetric deformation, which causes
structural damages to existing infrastructures. Damages due to expansive activities are …

The tendency of expansive subgrade soil to undergo swelling and shrinkage with the
change in moisture has a significant impact on the performance of the pavement. The …

Expansive soil in pavement subgrade experiences volume change due to the seasonal
moisture and temperature. For the clear understanding of the subgrade behaviour, it is …

Geotechnical spatial distribution was applied using the geostatistical interpolation approach
to improve the accuracy of spatial prediction of geotechnical data throughout the study area …
