← ScienceWhich outcome results when high humidity compromises roadway de-icing?
A)Increased re-freezing risk on the surface✓
B)De-icer induced corrosion is accelerated
C)Reduced thermal conductivity of the pavement
D)De-icer solution becomes hypertonic quickly
💡 Explanation
Increased hazard occurs because Humidity dilutes concentrated ionic de-icers via hygroscopic action, increasing the freezing point before the snow can melt. Therefore, re-icemay occur rather than complete melting because it becomes dilute with water.
