Determining the Soil Water Characteristic Curve and Interfacial Contact Angle from Microstructural Analysis of X-Ray CT Images
Publisher: American Society of Civil Engineers
Abstract: The complex behavior of unsaturated soils can be partly attributed to the co-existence of networks of liquid bridges and saturated pockets in the soil void space. Past studies have examined how the water bridges and pockets ...
X-Ray Computed Tomography and Nondestructive Evaluation of Clogging in Porous Concrete Field Samples
Publisher: American Society of Civil Engineers
Abstract: This study aims to investigate and quantify the fraction of clogging in pervious concrete samples cored from parking lots. Image observation, analysis, and processing of representative cores retrieved from parking lots ...
Microstructure-Based Effective Stress Formulation for Unsaturated Granular Soils
Publisher: American Society of Civil Engineers
Abstract: The principle of effective stress states that the strength and volume change behaviors of soil are governed by intergranular forces expressed in terms of a continuum quantity called effective stress. Although the principle ...
Laboratory Assessment of the Mechanical Properties of an Unsaturated Mid-Atlantic Silty Sand
Publisher: ASCE
Abstract: Natural soil formation processes involve variable particle size distributions that vary spatially within a deposit, giving rise to an array of soils that transition from one general soil type to another within essentially ...
