A Method for Evaluating Material Performance Parameters in Long-Life Structural Design under Random Degradation from Freeze–Thaw Cycles
(American Society of Civil Engineers, 2025)In long-life design of structures, material parameter values should be determined reasonably based on the design working life of the bridge and considering the degradation of the material properties during service. In this ... -
Micro–Macro Strength Criterion and Elastoplastic Constitutive Model for Frozen Mixed Soils
(American Society of Civil Engineers, 2025)Frozen mixed soils are widely distributed in the strata and slopes of permafrost regions. This paper aims to study the strength criterion and elastoplastic constitutive model for frozen mixed soils from micro to macro ... -
Assessing Variations in Sediment Properties and Erodibility in Harrison Bay, Alaska, Using a Portable Free-Fall Penetrometer
(American Society of Civil Engineers, 2025)Geomechanical data of Arctic nearshore and offshore seabed sediments remain sparse. Two field surveys were conducted in Harrison Bay, Alaska, in the summers of 2021 and 2022. These surveys involved portable free-fall ... -
A Unified Theoretical Thaw Expansion and Settlement Coefficient Model for Frozen Soil
(American Society of Civil Engineers, 2025)Thaw settlement and expansion of frozen soil pose significant risks to railway construction and maintenance in cold regions, particularly due to the greenhouse effect and extreme climate events. To address the thaw settlement ... -
Sustainability Enhancement of Inclement Weather Dummy Factor Model: A Study of Big Traffic Data in Canada

The Influence of Varying Subgrade Soil Compaction on the Relationship between Soil Water Content and Resistivity
(American Society of Civil Engineers, 2025)Quantifying the water content of subgrade soils is crucial for subgrade design and maintenance. As a noninvasive approach, the resistivity method is widely used for measuring the soil water content. However, the measuring ... -
A System for Investigating Water–Heat–Salt-Mechanics Coupling Effects in Saline Soil under Climate Change
(American Society of Civil Engineers, 2025)The global climate is becoming warmer and wetter, and the physical properties of saline soil are easily affected by the external climate changes, which can lead to complex water–heat–salt-mechanics (WHSM) coupling effect ... -
Temperature Effect on the Thermal Expansion Coefficient of Concrete
(American Society of Civil Engineers, 2025)The coefficient of thermal expansion (CTE) is typically assumed to be constant in RC bridge design. In fact, under freezing temperatures, the CTE of concrete exhibits hysteretic nonlinear response, which, however, is rarely ... -
Comparison of Antistripping Performance Evaluation Methods on Asphalt Runway Pavement in Cold Regions
(American Society of Civil Engineers, 2025)Influenced by aircraft engine wake effects, aggregates stripped off from asphalt runway surfaces are more severe during winter than during the other seasons in cold regions. In this study, five types of asphalt specimens ... -
Thermal Modeling of Small Modular Reactors in Permafrost Regions Subjected to Climate Nonstationarity
(American Society of Civil Engineers, 2025)Small modular reactors (SMRs) are an alternative for clean energy solutions in Canada’s remote northern communities, owing to their safety, flexibility, and reduced capital requirements. Currently, these communities are ... -
