A New Saturation-Based Framework for Compaction Quality Control
Publisher: ASCE
Abstract: Field compaction control is arguably the most common yet critical quality control procedure in geotechnical engineering. Since the early 1930s, the systematic process for performing quality control of compacted soils has ...
Full-Scale Testing of Lateral Pressures in an Expansive Clay upon Infiltration
Publisher: American Society of Civil Engineers
Abstract: Full-scale testing of lateral pressures in expansive clay under various saturation conditions is crucial to better understand the behavior of these soils and predict potential damage to structures. However, due to their ...
Impact of Toe Resistance in Reinforced Masonry Block Walls: Design Dilemma
Publisher: American Society of Civil Engineers
Abstract: Reinforced masonry block retaining walls are comprised of a narrow column of stacked blocks at their exposed end. This column is placed on a nonstructural leveling pad to facilitate the placement of facing units. Theoretically, ...
Mechanical, Chemical, Hydraulic, and Microstructural Properties of Buckshot Clay Amended with Gasification Biochar
Publisher: ASCE
Abstract: This study investigated the effect of gasification biochar amendment on mechanical, chemical, hydraulic, and microstructural properties of Buckshot clay, a high-plasticity clay with poor engineering properties. The ...
Critical Factors in Subgrade Rutting Failures of Airfield Mats over Soft Soils under Static Loading
Publisher: ASCE
Abstract: Subgrade rutting failures in matting structures present a unique challenge in expedient airfields. Mats are often constructed over existing soft subgrades and can experience aircraft with large gross loads and high tire ...
Model for Lateral Swelling Pressure in Unsaturated Expansive Soils
Publisher: ASCE
Abstract: Unsaturated expansive soils annually cause major economic losses and structural damages to foundations and earthen structures, primarily due to exhibiting large amounts of swelling and shrinkage when subjected to variations ...
Time-Dependent Deformation Characteristics of Unsaturated Sand–Bentonite Mixture under Drying–Wetting Cycles
Publisher: ASCE
Abstract: The main objective of this study was to investigate the primary consolidation and creep characteristics of two unsaturated sand–bentonite mixtures subjected to drying–wetting cycles. An extensive array of laboratory testing ...
Perceptions of Civil Engineering and Construction Students Toward Community and Infrastructure Resilience
Publisher: ASCE
Abstract: Civil engineering and construction (CEC) are among primary higher education programs preparing the next generation of subject experts and decision makers working on different aspects of infrastructure resilience, which is ...
Predicting Resilient Modulus of Unsaturated Subgrade Soils Considering Effects of Water Content, Temperature, and Hydraulic Hysteresis
Publisher: ASCE
Abstract: The resilient modulus, MR, of subgrade soils is an important parameter in design and analysis of pavements. Subgrade soils are often unsaturated and can experience a wide range of suctions due to changes in water content ...
A General Model for Temperature-Dependent Soil Suction
Publisher: American Society of Civil Engineers
Abstract: Soil suction is a crucial parameter that affects the behavior of unsaturated soils. The impact of temperature on suction can lead to significant changes in the hydromechanical response of unsaturated soils. However, current ...
