Key Facts
Corrosion
Responsibly inhibited calcium chloride is up to 92% less corrosive than rock salt used in the local market
Appropriately inhibited sodium chloride brine is 80% less corrosive than the uninhibited rock salt used today
Total chlorides
Effective use of liquids is shown to reduce total chlorides required to achieve desired service levels by ~30%
At recommended application rates (typically ~75 litres per lane kilometer), risk of product ‘splash’ or run-off before full dilution is minimal
Safety
Use of anti-icing liquids are proven to reduce accidents
City of Edmonton reported 19% fewer accidents on roads where anti-icing was used vs roads with no anti-icing directly benefiting public health and economy
Temperature
Calcium chloride remains effective at temperatures below -30°C
Rock salt is ineffective below -10°C
Sand
Sand is an effective tool for winter road management
Salt is an effective tool for winter road management at warmer temperatures (>-10°C), working once it becomes liquified
Use in conjunction with calcium chloride increases overall effectiveness and impact while reducing required quantities
Inhibited CaCl2
Significantly reduces sand, salt, total applied chlorides and corrosion levels
BOD
Road Guard Corrosion-free has almost undetectable levels of BOD
Snow Tires
B.C. legislation requires snow tires
B.C. also requires bare roads, using liquids for anti-icing to achieve the highest levels of public safety
Plows
Using plows alone to achieve bare pavement is costly with City of Edmonton estimating ‘$37M/year (+/- 50%)’ before considering any negative impact that plowing has on the city’s physical infrastructure
Increased plowing would greatly increase fleet maintenance costs, carbon emissions and complicate traffic logistics when roads are at their worst seemingly in opposition to the city’s declaration of a Climate Emergency this summer
Alberta Transportation
Inhibited liquid calcium chloride is on the QPL and is regularly used to positive effect on the Anthony Henday/other AB highways
