Application of PIV Technique in Model Test of Frost Heave of Unsaturated Soil
(ASCE, 9/1/2020 1)Frost heave of soil is a highly nonuniform problem, in which the local deformation is much more severe and meaningful compared with the overall deformation. When soil is upon freezing, a water–ice phase change occurs and ... -
Temperature-Dependent Thermal Performance of Closed-Cell Foam Insulation Board in Roof Constructions
(ASCE, 9/1/2020 1)Thermal performance of an insulation material is influenced by the in-service temperature condition. Unlike most other insulation materials, thermal resistance (R-value) of polyisocyanurate (polyiso or PIR) foam insulation ... -
Effect of Freezing on Stress–Strain Characteristics of Granular and Cohesive Soils
(ASCE, 6/1/2020 1)To investigate the stress–strain behavior of frozen soils, a program of triaxial compression tests was designed and carried out on samples of unfrozen and frozen cohesive (CL) and granular (SP) soils and pure ice. The ... -
Influence of NaCl Aqueous Solution on Compacted Snow: Field Investigation
(ASCE, 3/1/2020 1)Slippery road surfaces are a threat to traffic safety, especially in winter when snow falling on roads forms a hard crust that is extremely difficult to remove. To prevent this hard crust formation, salt is applied to ... -
Convective Heat Transfer in Crushed Rock Aggregates: The Effects of Grain Size Distribution and Moisture Content
(ASCE, 2020)This study deals with the susceptibility to convective heat transfer of the materials used in the Finnish rail network. Previous studies have found that convection clearly influences the thermal conductivity of coarse ... -
Snow Load Calculations for Alaska Using GHCN Data (1950–2017)
(ASCE, 2020)This paper presents the results of snow load calculations in Alaska based on measurements of snow depth and snow water equivalent from 1950 to 2017 acquired from the Global Historical Climate Network (GHCN). After cleaning ... -
Experimental Study of Sea Ice Motion in Waves
(ASCE, 2020)To better understand the interactions between ships and ice, analyze ice–ice collisions, and provide parameters for the design of ships and offshore structures, it is important to study the interaction between ice and ... -
Well Casing Subsidence in Thawing Permafrost: A Case Study
(ASCE, 2020)Deep ice lenses or excess ice in permafrost in Arctic oil fields on Alaska's North Slope, the Mackenzie Delta, or Eastern Siberia in Russia create challenging issues for oil well completion design. As thaw subsidence ... -
Assessment of Flexible Pavement Response during Partial Thawing Conditions Using Accelerated Pavement Testing
(ASCE, 2020)Damage to flexible pavements is known to be greatly influenced by climatic factors. Among them, partial thawing conditions encountered during winter warming periods, as well as in the early period of spring thaw, are ... -
Thaw Settlement and Mechanical Properties of Admixture-Stabilized Frozen Soil
(ASCE, 2020)Roads and other infrastructure in Western Alaska are difficult to design and build owing to the high cost of construction materials and the ice-rich permafrost foundation. The present study explores methods to treat locally ... -
Experimental Study on Salt Expansion Characteristics of Coarse-Grained Sulfate Soils
(ASCE, 2020)In this paper, salt expansion tests were conducted on coarse-grained sulfate soils to investigate salt expansion characteristics. The experimental results indicate that the formation and growth of salt crystals are influenced ... -
Estimation of Ground Snow Loads for Low-Latitude, High-Elevation Regions
(ASCE, 2020)The mountainous regions of the southern United States experience substantial snow loads. This study develops a data-driven method for determining 50-year ground snow load (GSL) in high-elevation, low-latitude regions and ... -
Estimating Unfrozen Water Content in Frozen Soils Based on Soil Particle Distribution
(ASCE, 2020)The unfrozen water content is a result of soil freezing, and its variation is closely related to temperature. To study the change in unfrozen water content, a relationship between water pressure and ice pressure is built ... -
Experimental Setup Simulating Hoarfrost Formation on Roadways
(ASCE, 2020)Hoarfrost on roadways and bridges can cause slippery and dangerous conditions for motorists. To reduce the costs and environmental impact of countermeasures, road authorities wish to optimize their winter maintenance ... -
Quantitative Comparison of Cone Penetration Testing Tip Resistance Data with Ground-Penetrating Radar Amplitude Data
(ASCE, 2020)Both cone penetration test (CPT) tip resistance data and ground-penetrating radar (GPR) amplitude data vary at the interface of snow layers of different density. Therefore, relationships between these data should be ... -
Model Test of Liquid Nitrogen Freezing-Temperature Field of Improved Plastic Freezing Pipe
(ASCE, 2020)Liquid nitrogen freezing technology is widely applied to reinforce the water-bearing ground around launching and receiving shafts of shield machines in subway tunnel construction projects. An improved liquid nitrogen ... -
Influence of Channel Morphology on Ice Conveyance and Bridging: Experiments with a Numerical Model
(ASCE, 2020)This paper presents findings from a numerical model used to conduct experiments regarding the influence of channel morphology on ice conveyance and bridging. The morphologies considered are meandering rectangular channels ... -
Quantification of Border Ice Growth on the Assiniboine River
(ASCE, 2020)Ice formation processes have been monitored on the Assiniboine River, Manitoba, by establishing an extensive network of hydrometric equipment and trail cameras. Although much of the study area is often subject to mechanical ... -
Ice-Floe Impact with a Rubble-Mound Causeway at the Port of Nome, Alaska
