RISDiscussion of “Tall Oedometer Testing: Method to Account for Wall Friction” by Julie Lovisa and Nagaratnam Sivakugan
Publisher: American Society of Civil Engineers
Deep Learning–Based Enhancement of Small Sample Liquefaction Data
Publisher: ASCE
Abstract: The liquefaction of sands remains an important topic in geotechnical earthquake engineering. The most widely used evaluation method is based on in situ testing means such as cone penetration test, standard penetration test, ...
Modified Time of Setting Test for Fly Ash Paste and Fly Ash–Soil Mixtures
Publisher: American Society of Civil Engineers
Abstract: A survey of current literature has revealed that the testing protocol for determining the time of setting of fly ash–soil mixtures is not available. Although the current ASTM standard recommends using the Vicat needle ...
Large-Strain Strength of Polymer-Modified Kaolinite and Fly Ash–Kaolinite Mixtures
Publisher: American Society of Civil Engineers
Abstract: Polymers have gained gradual attention in soil stabilization as a sustainable alternative to inorganic counterparts such as cement. However, the effects of polymers on the strength of soils and soil-waste mixtures are still ...
Effect of Foaming Agent on Physical and Mechanical Properties of Foamed Phosphogypsum
Publisher: ASCE
Abstract: Foamed phosphogypsum (FPG) has recently attracted extensive interest owing to its potential consumption of phosphogypsum and its substitution for traditional gypsum building materials. However, as an important component ...
Chemically Stabilized Soft Clays for Road-Base Construction
Publisher: American Society of Civil Engineers
Abstract: Soft clays are widely distributed in Missouri, United States. Due to their relatively low strength and high compressibility, subgrade construction in soft clays has encountered many difficulties. In recent practice, the ...
Strain-Controlled Cyclic Simple Shear Tests on Sand with Radial Strain Measurements
Publisher: American Society of Civil Engineers
Abstract: Strain-controlled cyclic simple-shear tests were performed on silica sand with radial strain measurements. The specimens were tested under a constant
Effects of Drying-Wetting Cycles on the Mechanical Behavior of Reconstituted Granite-Residual Soils
Publisher: ASCE
Abstract: In Central South of China, granite residual soil (GRS) is one of the main subgrade soils for transportation infrastructures. To further understand the effects of drying and wetting (D-W) cycles on the mechanical responses ...
Effective Tensile Strength of Lightly Cemented Sand
Publisher: American Society of Civil Engineers
Abstract: An indentation test was developed to indirectly determine the effective tensile strength of lightly cemented sand by iterative method. The description of the test is followed by a discussion and comparison of the determination ...
Soil–Geogrid Interaction at Various Influencing Factors by Pullout Tests with Applications of FBG Sensors
Publisher: American Society of Civil Engineers
Abstract: The behavior of soil–geogrid interaction is a dominant factor in the long-term performance of geogrid-reinforced earth structures. This study investigates the interaction of sandy soil and the embedded geogrid by pullout ...
