The expansion of soils on freezing is called “frost heaving.” Continued heaving is caused by growth of ice lenses. The pressure exerted against a load by this expansion is called “heaving pressure.” When frost heaving occurs, the water content (including ice) in the frozen zone is larger than the saturated water content of the soil, and the water content of the unfrozen zone below the freezing front is very low (Fig. 2.37). Water moves from the unfrozen soil to the freezing front, and from the freezing front to the ice lens. The unfrozen water films between ice and soil particles have an equilibrium thickness that decreases with decreasing temperature. Water migration in the frozen zone is through these films.
Control strategies for acid mine drainage in Arctic regions

Frost heaving occurs as a result of the formation of segregated ice, e.g., lenses and needles, as well as the volumetric expansion of water during freezing. Models are available to simulate and predict the mechanisms responsible for frost heaving (e.g., Chamberlain 1981, Black 8c Hardenberg 1991). Marion (1995) summarized the most important factors for the degree of frost heaving, including soil texture, pore size, freezing rate, temperature gradients, moisture and overburden stress. Frost heaving in tailings is considered a disadvantage as it produces cracks and preferential pathways that allow the infiltration of oxygen gas and oxygenated water. However, frost heaving is seldom observed in tailing areas, probably due to high ion concentrations that tend to reduce frost heaving. As pointed out by Sheeran & Yong (1975), this is to be expected because high ion concentrations increase the unfrozen water content and reduce the water available for forming segregated ice in tailings. Frost heaving may be important in cover materials provided as protection on top of tailings, and grain size and porosity should be considered in order to minimize frost heaving.

Numerical modeling of freezing and heaving allows obtaining a complete picture of temperature and moisture fields and the stress-strain state in the “structure/freezing soil” system, which makes it possible to determine all characteristics of frost heaving. In many cases, it is possible to refuse from performing time-consuming and expensive field experiments due to a simple variation of any parameters in numerical experiments.

Moisture-related distress significantly contributes to the deterioration and damage of pavements (Akentuna et al. 2023; Camacho-Garita et al. 2019). The infiltration of moisture into pavement systems gradually weakens their strength and affects their durability under sustained traffic loading over time. This problem is further exacerbated in cold regions by frost heaving and thaw weakening, resulting in substantial damage to construction and transportation infrastructure, including pavements and granular roadways. Consequently, it leads to significant economic costs and safety hazards (Sadiq et al. 2023; Naqvi et al. 2022). According to (Koks et al. 2019), the global annual damages due to direct damage to road and railway assets range from 3.1 to 22 billion US dollars, with approximately 73% of these damages being moisture-related. The United States faces particularly high costs associated with road infrastructure damage and has a high demand for road maintenance, which has significant environmental implications. Road construction has a substantial carbon footprint, with the production of the hot mix asphalt (HMA) layer in pavements emitting 65.8 kg of CO2 per kilometre of road (Espinoza et al. 2019).

Three conditions must exist for frost heaving to occur: the climate should be so cold that the freezing front can be initiated, a water supply should be available and a soil material that is susceptible to frost should lie within the freezing zone (Anderson et al.1984). Since the most straightforward approach to eliminate frost heaving is to avoid using frost-susceptible soil, this has been a research field of great interest during the last century. More than 100 different criteria have been proposed to assess whether or not a specific soil material is frost susceptible (Chamberlain 1981). Two of the most simple and well known of these are Casagrande’s and Schaible’s frost criteria, both of which build on a consideration of the soil particle size distribution. The soils being most vulnerable to frost heaving are those being sufficiently fine-grained to allow water to be held in the material, but at the same time being sufficiently coarse-grained to provide the necessary permeability to supply liquid water to the segregated ice (Rempel 2010).

The strength of unfrozen soil is low, and the action range of single hole liquid CO2 phase change fracturing is large. During the freezing process of soil, the liquid water in the soil concreting and filling the pores in the form of ice. The volume expansion of water phase changes in the soil body causes the frost heaving of soil, and the soil particles are cemented by ice, which eventually leads to the increase of frozen soil strength. Compared with unfrozen soil, the single hole action range of liquid CO2 phase change fracturing in frozen soil is relatively small. Therefore, the influence of frozen soil strength on fracturing effect should be fully considered when designing the scheme of liquid CO2 phase change fracturing of frozen soil.
