The research aims to enhance the energy efficiency of geothermal road snow-melting systems in cold regions using advanced pavement materials.
Developed a composite anti-icing modifier compatible with low enthalpy geothermal systems.
Conducted dissolution and soaking tests to analyze chloride ion release and structural durability.
Regulated the thermodynamic boundary of the pavement to lower the freezing point to −21 °C.
Optimal performance achieved with a 5% modifier dosage and a 5.3% bitumen aggregate ratio.
Ion release patterns exhibited a third-order polynomial trend and remained stable at 35 °C.
Validated in Xinjiang, showing only a 1.5% variation in performance over 20 days.
