Abstract:
The wide application of asphalt concrete in road construction has brought convenience to human travel, but road icing requires the application of deicing agents to prevent traffic accidents. However, the use of a deicing agent will also cause damage to the pavement material, so this paper carries out the research on the low-temperature performance of asphalt concrete with different concentrations of deicing agent solutions through the freeze-thaw cycle test. The test results show that with the increase in the number of freeze-thaw cycles, the five concentrations of deicing agent solution corresponding to the flexural tensile strength and maximum flexural tensile strain are decreasing trend. Although the deicing agent solution has a certain effect on the flexural tensile strength and maximum flexural tensile strain, the main effect on the reduction of the low-temperature performance of asphalt concrete is the frost damage caused by the freeze-thaw cycle.

Abstract:
Icy pavement is one of the primary causes affecting driving safety in winter, and deicing asphalt mixture could effectively resist pavement icing. This study evaluated the effect of a slow-release deicing agent on pavement performance and ice-melting characteristics of the asphalt mixture. The asphalt mixture containing four different contents (0%, 30%, 50%, and 70% using the internal mixing method) by replacing mineral filler was designed. Pavement performance tests were used to investigate the effect of the deicing agent on the high-temperature stability, cracking resistance, and water stability of the asphalt mixture. Qualitative and quantitative tests were designed to compare the ice-melting characteristics and predict the ice-melting durability with different replacement amounts. The experimental results show that the high-temperature stability, low-temperature cracking resistance, and water stability of the asphalt mixture decrease with the increase inthe deicing agent. The mineral filler with a content of 50% deicing agent will enhance the stability of the mixture in the short term. Deicing asphalt mixture can significantly improve the ice and snow melting ability of the pavement, and the asphalt mixture with a content of 50% deicing agent will reduce the interface adhesion between mixture and ice by more than 55%. The slow-release deicing asphalt mixture can reach the maximum release concentration within two hours under rain and snow. The recommended replacement amount of slow-release deicing agent is 50%, and the predicted durability of deicing asphalt mixture is 5–8 years.

Abstract:
In this study, a disaster management resource simulation model between local governments was suggested using the system dynamics methodology. At this time, the subject of analysis was selected as the stockpile of deicing agents for each district in Seoul. Based on statistical data, a scenario was set in which the expected amount of heavy snowfall reached level 3, and the response to heavy snowfall reached level 4 for 5 days in the 11 districts of Seoul. The simulation shows that in areas with heavy snow, the deicing agent stock falls below the minimum by the 4.5th day, and in areas without heavy snow, it happens by the 14.5th day. Additionally, it was estimated that the Seoul Disaster Resource Integrated Management Center required about 2,155 tons of deicing agents. This study is meaningful because it can be used to set the RTO(Recovery Time Objective) for the mobilization and support of deicing agents. Furthermore, it can be used to interconnect disaster management resources by suggesting an appropriate stockpile of deicing agents for the Seoul Disaster Resource Integrated Management Center.

Abstract:
The increasing use of deicing agents during winter, driven by abnormal climate changes such as global warming, has raised environmental concerns, including soil salinization, plant growth inhibition, road infrastructure corrosion, and elevated particulate matter (PM10) levels near roads. This study aimed to develop an eco-friendly deicing agent incorporating Ball Clay (Eco-Friendly Deicing Agent with Ball Clay, EDBC) and evaluate its dust suppression performance and physicochemical properties compared to conventional chloride-based deicing agents. The dust suppression performance of EDBC was evaluated using PM10 concentration measurements in a controlled chamber, comparing its effectiveness at different concentrations (5% and 30%) with calcium chloride (CaCl2) and sodium chloride (NaCl). Additionally, Scanning Electron Microscopy and Energy Dispersive Spectroscopy (SEM/EDS) analyses were conducted to assess the surface structure and physicochemical interactions of EDBC with dust particles. At a 5% concentration, EDBC achieved an average PM10 concentration of 174.03 μg/m3, significantly lower than CaCl2 (405.83 μg/m3) and NaCl (1256.67 μg/m3). Even at a 30% concentration, EDBC maintained the lowest dust concentration of 101.8 μg/m3. SEM/EDS analysis confirmed that EDBC formed a dense and uniform surface structure, enabling strong physicochemical binding to dust particles. In contrast, CaCl2 and NaCl, due to their high solubility and hygroscopic nature, showed limited dust suppression efficiency and posed challenges for long-term environmental sustainability. These results suggest that EDBC is a promising alternative to traditional chloride-based deicing agents, providing both effective dust control and environmental benefits.

Abstract:
Asphalt concrete pavement, as the main form of high-grade roads today, occupies an important place in modern road construction due to its advantages such as low noise level, ease of repair and short construction period. This road type is widely adopted worldwide and provides a reliable foundation for road networks in cities and villages. In cold regions, snowy weather tends to cause ice on the road surface, posing a serious safety hazard for vehicle travel. The problem of road accidents in winter is relevant both for regions with extremely cold climatic conditions and for the temperate continental climate that prevails almost throughout Ukraine. To solve this problem, deicing agents are widely used to improve the safety of road travel. The application of deicing agents effectively reduces the impact of snow and ice on roads and ensures the safe passage of vehicles in adverse weather conditions. However, while deicing agents play an important role in improving traffic flow, their widespread use has also brought some problems that should not be ignored. The chemicals in deicing agents may have adverse effects on pavement materials, especially on asphalt concrete roads. For studying the effect of deicing agents on asphalt concrete, this paper presents an experimental investigation of the effect of deicing agents on the water stability of asphalt concrete under the conditions of freeze-thaw cycle test. The impact of deicing agents and freeze-thaw cycles on asphalt concrete was investigated by evaluating the variation patterns of three key parameters: stability, residual stability and air void content. The experimental results showed that the stability and residual stability of asphalt concrete showed an overall decreasing trend with the increase of the number of freeze-thaw cycles, indicating that the asphalt concrete was damaged or degraded under the conditions of freeze-thaw cycles. The higher concentration of the deicer solution corresponded to the more pronounced changes in the test parameters, indicating a significant effect of the deicer on the asphalt concrete. At the end of 27 cycles, the average loss of stability, residual stability and void ratio were 29%, 22% and 73%, respectively. This indicates that the combined effect of freeze-thaw cycles and deicing agent is more significant for air void content.

Abstract:
Numerous studies have described the negative effects of the commonly used deicer, NaCl, on plants; this has led to research on less toxic alternatives, for example, calcium magnesium acetate (CMA). The present research investigated the native ground cover species, Arctostaphylos uva-ursi (kinnikinnick), as a possible candidate for landscaping in high salt conditions. The effect of NaCl and CMA on the growth, morphology, and survival of A. uva-ursi plants was examined to explore the use of CMA as a potential environmentally friendly alternative deicing agent to that of NaCl. The influence of these deicing agents on selected soil properties was also investigated. It was found that this ground cover species was able to tolerate moderate-to-high levels of NaCl and even greater concentrations of CMA. Therefore, A. uva-ursi proved to be a candidate for landscaping use in a north central city of Canada, where deicing agents are used in winter months.

Abstract:
Highway surfaces accumulate a wide range of pollutants (suspended solids, heavy metals, inorganic salts, aromatic hydrocarbons, oil and grease, rust and rubber particles, deicing agents, etc), which are washed off during rain or snow storm events into nearby waters or lands. This dissertation presents the impact of highway runoff to soil and groundwater. The dissertation is composed of two major distinct parts. First part assessed the bacterial community diversity in highway runoff contaminated sediment from an infiltration basin located in Plymouth, MA that had undergone nineteen years of acetate-based de-icing agents addition followed by three years of acetate-free de-icing agents. Sediment sample from four drilled soil cores collected in two field events documented the change in bacterial community structure with depth and distance from the infiltration basin origin. To meet the objective, a variety of multi-disciplinary techniques were employed. Soil samples were collected, using drilling and core barrel / freeze-shoe coring methods, from different locations and depths to obtain vertical profiles of bacterial distribution along groundwater plume. Analyses of groundwater dissolved oxygen and pH, physical and chemical properties of the soil complemented molecular phylogenetic determinations to distinguish ambient and contaminated plume zones. Analysis of sediment samples from four drilled soil cores by means of 16S rDNA PCR indicated an overall high bacterial diversity both into the plume and into the ambient aquifer, with no prominent members within the communities. Sequence analyses provided evidences that each sediment sample displayed a specific structure bacterial community. Proteobacteria-affiliated clones (50%) predominated in all samples, followed by Actinobacteria (14%), Firmicutes (10%) and Chloroflexi (9%). Statistical analysis revealed that the levels of Fe(II) and dissolved oxygen were strongly correlated with bacterial communities. The plume in the infiltration basin was anaerobic and iron reducing. As iron levels declined as oxygen levels increased below the plume bottom, there was a gradual shift in the community structure toward the increase of aerobic bacteria. These data indicate shifts in microbial communities in correlation with depth, substrate and oxygen availability in a deicing agent impacted subsurface. The second part of the dissertation investigated the subsurface fate and transport of deicing materials on groundwater quality across silt deposits in Dedham, Massachusetts. The deposit analyzed consists of two layers: a silty sand floodplain that is underlain by an aquitard, comprised mainly of silt. The aquitard overlies a confined aquifer, that is used as a public water supply. Soil and groundwater from the Neponset River aquitard and overlying floodplain deposit that receive high concentrations of deicing agents from nearby highways were collected and analyzed. Soil and groundwater samples collected over a period of four years from boreholes and 10 wells grouped in two well clusters were analyzed for dissolved chloride concentration. These data calibrate a one-dimensional, vertical dispersive transport model across the deposits. The flow and contaminant transport in floodplain is controlled by the aquitard presence and its low permeability. Soil and groundwater quality data confirmed a high chloride concentration at the floodplain surface near the highway runoff drainage outlets. These data confirmed the aquitard's capacity to contain deicing agents over decadal time frame, protecting the underlying aquifer from contamination.

Abstract:
&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;One of the most significant challenges for the aviation industry in the winter is the deicing operations on runways. As a result, deicer chemicals can pollute the environment if used in a large amount. A mathematical model could help optimize the use of deicer chemicals. Road deicing models exist to predict pavement temperature covered by snow/ice during deicing operations. However, the specificity of airport operations requires a model for the runway deicing to simulate the mass of ice melted with usage of deicing agents. Here we propose a model for runway deicing and validate it against experimental results. Our model considers temperature, diffusive flux, and time changes in a normal direction. It also calculates the mass and heat transfer in three regions (liquid, mushy, and solid). We used the enthalpy method to determine the temperature and the interface location at each time step. In the liquid and solid, the deicer concentration is obtained by Fick’s law and updated at each time step and location. The melting point temperature is variable due to the dilution of the deicer in the solution. Therefore, melting points are updated depending on the concentration at each location and time. The model uses the phases diagram for water and deicer agent mixture, considering eutectic point, for melting point calculation. The mesh dependency of the model is first investigated. To verify the model sensitivity, the paper proposes parametric studies for the heat transfer coefficient and the diffusion coefficients. Then, to validate the model, the Anti-Icing Materials International Laboratory (AMIL) in Chicoutimi conducted experimental tests on deicer agents for runways. Validation of the model is achieved for potassium acetate and potassium formate, two types of deicers.&lt;/div&gt;&lt;/div&gt;

Abstract:
Fiber-reinforced polymer composites are attractive structural materials due to their high specific strength/stiffness and excellent corrosion resistance. However, the lack of through-thickness reinforcement in laminated composites creates inherent susceptibility to fiber-matrix debonding, i.e., interlaminar delamination. This internal damage mode has proven difficult to detect and nearly impossible to repair via conventional methods, and therefore, remains a significant factor limiting the reliability of composite laminates in lightweight structures. Thus, novel approaches for mitigation (e.g., self-healing) of this incessant damage mode are of tremendous interest. Self-healing strategies involving sequestration of reactive liquids, i.e. microcapsule and microvascular systems, show promise for the extending service- life of laminated composites. However, limited heal cycles, long reaction times (hours/days), and variable stability of chemical agents under changing environmental conditions remain formidable research challenges. Intrinsic self- healing approaches that utilize reversible bonds in the host material circumvent many of these limitations and offer the potential for unlimited heal cycles. Here we detail the development of an intrinsic self-healing woven composite laminate based on thermally-induced dynamic bond re-association of 3D-printed polymer interlayers. In contrast to prior work, self-repair of the laminate occurs in situ and below the glass-transition temperature of the epoxy matrix, and maintains &gt;85% of the elastic modulus during healing. This new platform has been deployed in both glass and carbon-fiber composites, demonstrating application versatility. Remarkably, up to 20 rapid (minute-scale) self-healing cycles have been achieved with healing efficiencies hovering 100% of the interlayer toughened (4-5x) composite laminate. This latest self-healing advancement exhibits unprecedented potential for perpetual in-service repair along with material multi-functionality (e.g., deicing ability) to meet modern application demands.
