What Affects Commercial Asphalt in Minneapolis & St. Paul?

In Minnesota, there is a lot of snow, rain, ice, and fluctuating temperatures. There is also a lot of asphalt that experiences heavy traffic and snow that is then removed to make the surface safer. Basically, the commercial asphalt throughout Minneapolis and St. Paul goes through quite a bit, but that doesn’t mean that it can’t last 15 years if it is taken care of properly. The following are some common issues seen by asphalt in this part of the country.


Everyone who lives in Minnesota knows all about its weather. Weathering is the daily moisture and temperature fluctuations that are experienced by the paved surface. When asphalt is first laid, it is a very dark black color. This indicates that the pavement is flexible, moist, and resistant to chemical and water penetration.

Over time, the temperature fluctuations, sunlight, and chemical exposure breaks down the asphalt and the color begins to fade. As the pavement breaks down, it becomes more susceptible to potholes, cracks, and divots.

Through properly maintaining an asphalt surface, its useful life is extended. Proper maintenance includes seal coating the parking lot or road, identifying and repairing cracks and pot holes, and also knowing when it is time to replace the entire surface.


Bleeding is also called “flushing” and it is a type of pavement damage that is caused when an asphalt binder leaks through the pavement’s surface, creating a shiny, black coating. This bled material becomes messy and sticky and can create a very slick area when it rains.

This is something that happens when too much asphalt has been used in the construction mix or when excessive sealant has been used in joints and cracks. It is possible that seal coating has been improperly mixed when this has happened. The heavy traffic aggravates the asphalt, causing the bleeding and this can create bleeding and ruts along tire tracks. The good news is that a coarse sand mixture spread across the paved surface to soak up the excess material can stop it. In some cases, the area needs to be resurfaced.


Raveling occurs when the pavement binder has excessively hardened or the mixture was of a poor quality. Raveling makes the surface more susceptible to ice, sunlight, and temperature fluctuations, which causes the surface to deteriorate faster. An overlay treatment to smooth out or seal the road can rectify this problem.

Polished Aggregate

When soft aggregate is used to create the pavement, it will polish under tire wear and heavy traffic. This can make the surface slick to the point it becomes very dangerous in wet or icy conditions. A non-stick slurry seal can be applied by your Asphalt contractors to stop this and give the surface the traction that it needs to have.

Aggregate Loss

Aggregate loss can occur as well when the asphalt is not immediately spread and compressed or it is left to cool at a less than optimal temperature. There are ways to fix this as well, such as spreading a hot, coarse sand mixture over the surface and compressing it with a pneumatic tire roller instead of the usual steel wheel roller
