What Is The Best Ice Melt For Asphalt?

Winter is just around the corner, and with that comes freezing temperatures, snow, ice, and the chaos of it all. Ice and snow can mean trouble for your asphalt surface, not only in terms of safety concerns, but also in terms of your asphalt structure itself. The freeze-thaw cycle, snow removal, ice melt, snow piles, and ice accumulation can all lead to pavement damages. Effectively managing ice, and preventing slips, accidents, and unsafe conditions in your parking lot is hugely important. However, before choosing your snow melt solution for the season, you’ll want to understand what the best ice melt for asphalt is.

There are a ton of ice melt products on the market, but not all are best suited for all surfaces. The best asphalt salt will differ from the best ice melt choice for concrete. Luckily, asphalt is one of the most resilient materials used for pavement surfaces, and because of this, you have more snow melt options available to you than a material like concrete. But, just because asphalt is resilient, doesn’t mean that all salting agents are best for asphalt.

Here are some of the best ice melt options for your asphalt surface –

  1. calcium chloride ice meltCalcium Chloride (Crystals, Flakes, Pellets) – The good news is, Calcium Chloride is one of the most popular ice melt agents on the market. It typically comes in the form of crystals, flakes, or pellets. Calcium Chloride can perform in as low as -25 degrees F and is fast acting. Being able to perform at such low temperatures means that the asphalt is greatly protected from the risks associated with the freeze-thaw cycle.
  2. Magnesium Chloride – This is typically sold in pellet form. While Magnesium Chloride is often just as effective (especially in our area), it can only perform in as low as 0 degrees F.
  3. Calcium Magnesium Acetate – As you may have guessed by the name, this type of ice melt agent combines the two. This material will work down to -25 degrees F and is safe for your asphalt. It is also approved for use around children and pets.

Sodium Chloride or Rock Salt –

rock salt ice meltSodium Chloride is a very common ice melt product, and is essentially what you would find in your kitchen salt shaker. It is very inexpensive, and this is probably one of the reasons why it’s so popular. However, it is not the safest or most effective ice melt product. Rock salt or Sodium Chloride products will only work down to about 15 degrees F. While the temperature does not often get below 15 in our area, it leaves more room for activation of the freeze-thaw cycle, and the damages that come with that. Additionally, Sodium Chloride is not very economically friendly and can be harmful to your pets. Here are some additional effects rock salts and deicers can have on your asphalt.
