Abstract
A freeze-preventing material comprises cement, salt, and water-absorbing resins. The freeze-preventing material is scattered on the pavement surface in the form of slurry to prevent the pavement surface from freezing. Thereby a freeze-preventing effect is maintained for a long period of time owing to the water-absorbing resins which absorb and retain the salt in large amounts. The anti-freezing effect can be restored by spraying the pavement with the salt again.
