Strength, Microstructure, and Deformation Behavior of Frozen Cemented Tailing Material
(ASCE, 2022-3-1)Cemented paste backfill (CPB) is a novel cementitious construction material that is used extensively for underground mine support and/or mine waste management worldwide. CPB consists of a mix of tailings (mine waste), ... -
Experimental Study of the Anisotropic Frost Heave Characteristics of Rock Surrounding Tunnels in Cold Regions
(ASCE, 12/1/2021)Considering the characteristics of the surrounding rock temperature and water replenishing direction of tunnels in cold areas, to study the frost heave deformation law of surrounding rock under a certain stress environment, ... -
Quantitative Analysis of the Microstructures of Deep Silty Clay Subjected to Two Freezing–Thawing Cycles under Subway Vibration Loading
(ASCE, 12/1/2021)The bypass of subway tunnels in soft soil areas is usually constructed by the artificial freezing method due to the waterproof property and high strength of frozen soil. The thawing settlement and deformation of silty clay ... -
Environmental, Economic, and Operational Impacts of Roadway Winter Maintenance: Salt Brine Field Evaluation
(ASCE, 12/1/2021)Transportation agencies have been introducing responsible and sustainable winter maintenance practices to alleviate impacts on the environment, human health, vehicles, infrastructure, and reduce costs. Salt brine implementation ... -
Conceptualizing How Agencies Could Leverage Weather-Related Connected Vehicle Application to Enhance Winter Road Services
(ASCE, 9/1/2021)Winter inclement weather negatively influences the safety, mobility, economy, and user experience of roadway transportation systems. Ice and snowfall conditions result in more accidents and casualties and reduce the travel ... -
Thermal Stabilization of Embankments Built on Thaw-Sensitive Permafrost
(ASCE, 9/1/2021)As a result of climate change and design techniques poorly adapted to permafrost conditions, thermal degradation of permafrost underneath transportation infrastructure is leading to infrastructure instability and increasing ... -
Freeze–Thaw Resistance of Nonproprietary Ultrahigh-Performance Concrete
(ASCE, 9/1/2021)In cold regions, early deterioration of concretes due to freezing and thawing is a major concern. This study determined the freezing and thawing resistance of ultrahigh-performance concretes (UHPCs) made with different ... -
Characterizing Ice Cover Formation during Freeze-Up on the Regulated Upper Nelson River, Manitoba
(ASCE, 9/1/2021)Flow control programs on regulated rivers can improve winter flow conveyance for hydropower operations. On the Upper Nelson River, station flows at Jenpeg Generating Station are reduced during freeze-up to promote formation ... -
Mechanism of Radial Stress in the Freezing Direction Produced by Non-Frost-Susceptible Materials
(ASCE, 6/1/2021)Radial stress produced by the freezing of soil mainly results from two parts: the segregated ice lens and the in situ freezing of pore water. However, most studies concentrate on the stress of freezing direction, but little ... -
