Ensuring The Smooth Surface Of Your Parking Lot

by Kathy Knight

If you have a business with a paved parking lot, then you may need to invest in a repaving at some point. This is ideal if the asphalt is cracked and broken and if water is starting to seep into cracks and freeze. You most likely want the repaved surface to be as smooth as possible, and there are many things that your paving contractors will do to ensure the smoothness. Keep reading to learn about some of these practices.

Leveling Subgrade

Many freeze and thaw cycles can cause the ground underneath a paved service to heave towards the surface. This can cause cracks, openings, and generally uneven surfaces across your parking area. If the ground is also congested with water, then heaving may be an even greater issue due to the freezing of the water in the earth.

To make sure that heaving issues are not a concern, contractors will level out the subgrade. This sometimes requires the full replacement of soil materials as well as the gravel that sits on top of it. If the soil is weak, this replacement process can help strengthen the ground. If the earth is rocky, then this can help to remove the larger stones that contribute to heaving issues. 

Also, when excavation is completed, the earth is investigated for drainage issues. If pooling water is problematic, then drainage lines may be added to move the water away from the parking lot, thus stopping the water from freezing underneath it.

Using Rollers And Release Agents

Another practice that helps to smooth the paving surface is the use of rollers that compress the asphalt and allow the bitumen and rock materials to bind together into a more solid surface. As the rollers compress and move along the pavement, they sometimes pick up small bits of the rocky asphalt material. This can create small and uneven divots in the surface. 

To keep divots at bay, professionals spread a material along the surface of the rollers called a release agent. This is typically a water-based lubricant that keeps the bitumen and rock from sticking to the roller.

Many professionals will use rollers that have special coatings, so sometimes the release agents are not required. If they are needed though, they are often spread on the roller's surface with an integrated spraying apparatus installed directly on the machine. 

If you want to know more about asphalt paving and how your parking lot will be constructed to retain its smoothness, speak with a professional company, such as Arrow Blacktop & Masonry Inc.
