Three methods commonly used in snowmelt;

1) Pre-wet treatment, such as snow removal, salt and sand first mixed, then sprinkled into the ice and snow, in order to improve the efficiency of snow melting

2) spraying before fog, using snow melting agent before fog. The general new type of snow melting agent can be kept for 1 ~ 2 weeks on the road, and the amount of spraying is 35 ~ 95.

3) after fog, the dosage is usually 80 ~ 150L / km.
