RISMoisture Hysteretic Behavior of Fine-Grained Soils Stabilized with Lime and Class C Fly Ash
Publisher: American Society of Civil Engineers
Abstract: Seasonal conditions (e.g., rise in the water table, precipitation, freeze–thaw cycles, and wet–dry cycles) affect stabilized subgrade moisture conditions which, in turn, have a significant impact on in-service pavement ...
Modeling, Animating, and Optimizing On-Shore Wind Farm Construction Operations
Publisher: American Society of Civil Engineers
Abstract: Recently, wind energy has been greatly sought after because of the high price and diminishing quantity of fossil fuel resources. This necessitated the construction of wind farms. However, the on-shore wind farm construction ...
Modeling Resilient Modulus Hysteretic Behavior with Moisture Variation
Publisher: American Society of Civil Engineers
Abstract: The changes in subgrade moisture conditions play an important role in the in-service performance of a pavement. These conditions are sensitive to environmental conditions, such as a rise in the water table, precipitation, ...
Impact of Backfill Material on the Rerounding of Deflected Corrugated High-Density Polyethylene Drainage Pipes
Publisher: ASCE
Abstract: Rerounding is a technique for remediating excess deflection in thermoplastic pipe. A pneumatic device vibrates along the vertical axis and pushes against the inside crown and invert to restore the original pipe shape and ...
Performance of a Stabilized Aggregate Base Subject to Different Durability Procedures
Publisher: American Society of Civil Engineers
Abstract: This study examined the effects of two freeze-thaw (FT) laboratory procedures, FT-1 and FT-2, on stabilized aggregate specimens. Cylindrical specimens were stabilized with 10% Class C fly ash (CFA) cured for selected periods ...
Passive Earth Pressure of Overconsolidated Cohesionless Backfill
Publisher: American Society of Civil Engineers
Abstract: An experimental investigation on the passive earth pressure of overconsolidated cohesionless soil on retaining walls was conducted. A prototype model of a vertical rough wall, retaining horizontal backfill, was developed ...
An Efficient Algorithm for Shortest Path in Three Dimensions With Polyhedral Obstacles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An algorithm to find the shortest path between two specified points in three-dimensional space in the presence of polyhedral obstacles is described. The proposed method iterates for the precise ...
Environmental Effects on Durability of Aggregates Stabilized with Cementitious Materials
Publisher: American Society of Civil Engineers
Abstract: The present study focuses on investigating the effect of freeze–thaw (FT) cycles, referred to as environmental effect in this paper, on aggregates stabilized with various stabilizing agents, namely, cement kiln dust (CKD), ...
Engineering Properties and Moisture Susceptibility of Silty Clay Stabilized with Lime, Class C Fly Ash, and Cement Kiln Dust
Publisher: American Society of Civil Engineers
Abstract: A laboratory study was undertaken to evaluate the effectiveness of different percentages of hydrated lime, class C fly ash (CFA), and cement kiln dust (CKD) as soil stabilizers. Cylindrical specimens were compacted and ...
Finite-Element Modeling of Cementitiously Stabilized Beams Using a Smeared Fracture Approach
Publisher: American Society of Civil Engineers
Abstract: Cracking is considered a vital distress in a pavement structure. It generally initiates and propagates (bottom up and/or surface down) causing damage to the overall pavement structure. Most previous numerical modeling ...
