Abstract: A rational method for estimating soil suction variations within the so-called moisture active zone or vadose zone is required. Within the unsaturated zone, a soil suction envelope is defined by the maximum and minimum ...

Abstract: Moisture damage in asphalt pavements can produce rapid failures costing millions of dollars to repair. Surface energy interactions between the asphalt binder and aggregate are known as the fundamental approaches to predicting ...

Abstract: Climatic conditions easily allow for volume change of expansive soils. This happens due to the wetting and drying cycles that affect the moisture active zone. The suction compression index (γh) is the key parameter that ...

Abstract: Compacted and undisturbed expansive soils have widely been modeled as dual-porosity materials with two levels of pore systems: micropores and macropores. The micropores accommodate the soil activity of swelling and shrinkage ...

Abstract: This paper presents experimental results and analysis of sulfate-bearing soils treated with ground granulated blast-furnace slag (GGBS). The experiments involve the unconfined compression strength test, shrinkage, free ...
