“…q is heat flux, and the subscript s represents the road surface. When the energy balance equation is written for the plain concrete surface, the heat flux of the surface is exerted based on the surface-ambient heat interaction mechanisms and the balance equation can be written as in Equation (7) [50,51]…”

“…Snow and ice formation on driveways in winter results in serious risky situations and safety concerns that also cause serious delays and cost drawbacks in daily life [1][2][3][4]. From past to present, many studies focused on economically viable snow and ice removal methods for densely populated areas (e.g., overpopulated living areas), public areas (e.g., hospitals, municipal buildings), and transport infrastructure (e.g., airports) as explained in detail by recent critical review studies [5][6][7][8][9]. In general, these methods can be divided into two types: passive and active.…”

Snow and ice forming on the entrance and exit driveways of underground car parks of buildings brings serious difficulties and risks in safe parking for vehicles in winter. Even though traditional methods such as chemical salt and snow plowing reduce slippery conditions on driveways, they also result in infrastructure- and environment-related damages. Hydronic heating is an alternative way to prevent snow and ice forming; thereby, the hydronic heating driveway (HHD) is a promising technique for energy-efficient and environment-friendly solutions. This study presents a time-dependent three-dimensional numerical heat transfer model for HHD applications with realistic boundary conditions and meteorological data in the MATLAB environment. After developing the numerical heat transfer model, the model is applied to a case study in Istanbul, Turkey and followed by an economic comparison with the commercial electrically-heated driveways (EHD) method that is applied in two different ways; applying the electric cables in (i) whole driveway and (ii) only tire tracks. Different escalation rates in natural gas and electricity, hot fluid inlet temperature, air temperature, and the number of parallel pipes are the main parameters in the case study. Results show that the decrease in pipe spacing drops the investment cost term but it needs a higher supplied fluid temperature for anti-icing, and therefore the operating cost term increases. Among other cases was the number of parallel pipes, with 50 being the most economically feasible solution for all air temperatures ranging from 0 °C to −10 °C. The economic comparison shows that the EHD with only tire tracks has the minimum total cost as it significantly decreased both the operating and investment cost terms. In case of an anti-icing requirement on the whole road surface, the HHD system was found to be preferable to the EHD whole driveway scenario at air temperatures of 0 °C and −5 °C, while it is more beneficial only for the high electricity escalation rates at the ambient temperature of −10 °C.

“…At present, deicing technologies include conductive concrete [ 1 , 2 , 3 ], circulating heating systems [ 4 , 5 , 6 ], electric cable heating [ 7 ], solar energy [ 8 ], geothermal systems [ 9 , 10 ], induction heating, microwave heating [ 11 ], etc. Compared with the above deicing technologies, self-ice-melting asphalt pavements with salt-storage additives have the advantages of relatively low cost and easy construction.…”

Based on laboratory tests, the objective of this study is to assess long-term road performance and to predict deicing longevity of self-ice-melting asphalt pavements containing salt-storage materials. Dry–wet cycles and freeze–thaw cycles were used to treat the specimens at different durations. The long-term road performance of self-ice-melting asphalt mixtures was evaluated by freeze–thaw splitting tests, high-temperature rutting tests, and low-temperature beam bending tests. In addition, the influences of coefficients of void ratio, temperature, vehicle load, crack, and Mafilon (MFL) content on salt precipitation were quantified by conductivity tests, and single consumption of snow and ice melt was quantified by total dissolved solids (TDS) tests. The results show that the long-term water stability, long-term high-temperature stability, and long-term low-temperature crack resistance of self-ice-melting asphalt pavements tended to decrease as the number of dry–wet cycles and freeze–thaw cycles increased. Freeze–thaw cycles exerted deeper influences on the deterioration of road performance than dry–wet cycles, especially on water stability. With increased void ratio and temperature, salt precipitation was accelerated by 1.1 times and 1.5~1.8 times, respectively. Under vehicle loads and cracks, salt precipitation was accelerated by 1.5 times and 1.65 times, respectively. With decreased MFL content, salt precipitation slowed down by 0.54 times. Finally, based on the proportion of each factor relative to the whole life cycle of the pavement, a dicing longevity prediction model was established considering the above factors.

In winter months, it is serious problem for vehicles to enter and exit the car park due to snow or ice formed on the road surface of underground car park of highrise buildings or residences in metropolitan cities. In order to reduce slippery conditions on a road surface, some conventional methods are used that are mechanical, such as chemical salt sprinkling or snow plowing. Since these methods cause both road infrastructures and environmental problems, the use of Hydronic Heating Pavement (HHP) method, which is a more greener and alternative method, comes to the fore. The HHP method consists of PEX pipes placed under underground car park road surfaces and hot fluid passing through them. In this study, a new model has been developed for the HHP system in order to prevent snow or ice formed on the underground car park road surfaces. However, the novelty of proposed model is that instead of implementing an additional heating system such as a boiler or heat pump as the heat source, the
