In areas with extreme winters, asphalt faces several challenges:

 Freeze-Thaw Cycles: Water seeps into tiny cracks and pores in the asphalt, expanding when it freezes and contracting when it thaws. This cycle weakens the structure over time.

Heavy Use of Salt and De-Icers: Chemicals designed to melt ice can also degrade certain types of asphalt

Subzero Temperatures: Very low temperatures make asphalt more brittle and prone to cracking under weight, especially from heavy vehicles.

Given these challenges, choosing the best type of asphalt for cold weather is essential to ensure the longevity of roads, driveways, and parking lots.

Best Types of Asphalt for Cold Climates

Not all types of asphalt can handle these conditions effectively. Here’s a closer look at a few varieties that First Water Contracting recommends to keep surfaces intact through winter’s worst:

1. Modified Binder Asphalt (SMA)

Stone Matrix Asphalt (SMA) is a top choice for cold climates, featuring a high-strength, stone-on-stone skeleton designed to resist the stresses of freeze-thaw cycles. SMA uses durable aggregates and a strong binder that’s mixed with polymers to enhance flexibility, making it more resistant to cracking in subzero temperatures.
    •    Benefits: Exceptional durability, resistance to rutting, and superior ability to withstand cold conditions.
    •    Best Uses: High-traffic roads, highways, and areas subjected to repeated freeze-thaw cycles.

Polymer-Modified Asphalt (PMA) incorporates synthetic polymers that improve elasticity and flexibility, allowing it to absorb stress without cracking. This quality is especially valuable in cold weather, where asphalt is more vulnerable to brittleness and fracture.
    •    Benefits: Better resistance to cracking and rutting, increased durability, and reduced maintenance needs.
    •    Best Uses: Parking lots, driveways, and roads that experience heavy vehicle traffic.

Cold Mix AsphaltCold Mix Asphalt is ideal for quick repairs and temporary fixes in winter months when regular hot mix asphalt is hard to apply due to freezing temperatures. Cold mix contains additives that make it malleable and adhesive even in cold conditions, making it a versatile option for emergency pothole repairs.
    •    Benefits: Easy application in cold weather, ideal for patching and small repairs.
    •    Best Uses: Temporary patches, small pothole repairs, and emergency fixes during winter.
