The potential damage of asphalt driveways in Sydney during winter –
(a) Salt & Deicers – They can contribute to making potholes and other asphalt issues worse by keeping water in liquid form at lower temperatures while the deicers do not technically deteriorate your asphalt on their own. At varying temperatures, this allows for the freeze-thaw cycle to occur.
(b) Snow Removal – It can cause damages by any scraping against your pavement with heavy machinery. On curbing and uneven areas of the surface, most damages associated with snow removal will occur.
(c) Water – In winter, there is more of it as water is one of the most damaging elements to asphalt. Your asphalt is more vulnerable to damages.

In regions which experiences moderate to severe winters, asphalt repair is pretty routine maintenance in practice. The dangers and annoyances caused for traffic and properties are what potholes are for.
When objects get cold or freezes, they expand and contract as the basic science dictates. Pavement contraction often forms cracks during the winter months. These cracks can cause much larger issues in the future like potholes as they start small hairline flaws.
The following are the reasons for how potholes are formed:
(a) Over the time the cracks naturally get deeper.
(b) Temperatures fluctuate from freezing to above freezing during the winter.
(c) When temperatures reach above the freezing the ice which forms within the pavement cracks melts and turns to water at the surface level during the day. The deeper part of the pavement remains frozen.
(d) When the temperature drops again at night the surface water sitting within the pavement crack freezes.
It expands lifting the pavement creating a bump when it refreezes.
(e) The ice under the pavement bump melts but the bump created in the pavement remains the next day when the temperature increases again.
(f) The pavement gets crushed creating a hole when car then drives over the hollow bump.
(g) Creating a larger hole each time, this process will continue over and over. In the following winter months, this is the reason why large potholes are seen nearly everywhere.
Maintenance and repairs are often inevitable as the harshness of winter is unavoidable. There is a couple of asphalt pothole repair methods which works the best if your pavement is left with numerous potholes the following winter.
(a) Hot asphalt patching
(b) Saw-cut patch
