Selon la présente invention, la résistance, l'adhésivité, la résistance à l'usure et la durabilité sont excellentes et l'agent de prévention de gel peut maintenir une fonction de prévention de gel de haut niveau, de telle sorte qu'un accident de glissement sur une route enneigée ou une détérioration de mobilier urbain peuvent être empêchés. De plus, il est possible de produire une composition qui modifie le rapport et les conditions physiques d'ingrédients initiaux et, par conséquent, qui présente un effet antigel à long terme, qui n'est pas nocif pour l'environnement, qui ne corrode pas un métal et qui empêche le givrage répété, si la température environnante chute. De plus, la composition pour le traitement de surface de prévention de gel et le procédé de traitement de surface de prévention de gel pour chaussée utilisent un agent de prévention de glissement ayant une vitesse de durcissement rapide et d'excellentes performances d'adhésif de surface de route et d'excellentes caractéristiques physiques à long terme en même temps et ont un effet innovant de résolution complète des problèmes d'une construction de fonte de neige ou de prévention de gel de l'état de la technique, qui présente une configuration complexe et un coût de fonctionnement élevé en raison d'un coût d'installation et d'une consommation d'énergie élevée.
