Abstract:

In order to explore the snow melting and anti-freeze performance of salt storage asphalt mixture (SSAM), the influence of salt, temperature, and soaking time on the adhesive property, deicing property, ice inhibition property, and long-term snow melting property of mixture was investigated by scratch, torsion, ice inhibition, and conductivity experiment, and the equation of salt dissolution and soaking time was established. The results showed that the ice surface torsion force of SSAM was less affected by temperature, and the change was only 1.1 N center dot M. SSAM achieves the effect that light snow is easier to dissolve and heavy snow is easier to remove. With the decrease in temperature, the ice inhibition grade of SSAM decreases gradually. The corresponding salt dissolution rate gradually decreases in the early, middle, and late stages, and the final amount of salt dissolution is 88.13%. Therefore, the evaluation methods of snow melting and anti-freeze performance are proposed, which could provide an important reference for the popularization and application of SSAM.
