Why Asphalt Thickness Matters
As already mentioned, parking lot paving requires a significant investment of time and money. And ensuring the proper thickness is essential to protect your investment. The right thickness will also prevent premature deterioration of your pavement.
Ideally, your asphalt paving contractor will ensure the right thickness for your parking lot. But several contractors cut corners and pave thin asphalt layers. That’s why it’s essential that you only hire a reliable asphalt paving company with sufficient knowledge of the thickness required for a parking lot.
Asphalt Thickness Depends On Usage
The purpose of your pavement will determine the appropriate asphalt thickness. While we are talking about parking lots, specifically, we still need to consider the size of the lot and daily traffic volumes.
2.5 – 3 inches of asphalt over a 6-inch aggregate base is sufficient to handle light traffic. If you have trucks and other heavy-duty vehicles entering your lot, like forklifts, keep the thickness at 6 inches for your asphalt. You should place clear signs on your parking lot to direct heavy traffic in locations with sufficient thickness.
Asphalt thickness also depends on the quality of the soil underlying your pavement. Your geotech or architect will inspect the ground before determining how thick your parking lot should be and will let your asphalt paving contractor know. Also, what will be determined ahead of time is the drainage of the parking lot because proper drainage is another factor that contributes to the durability of asphalt pavement.
Other Factors That Influence Asphalt Thickness
Along with the type of soil, the sub-base also impacts the thickness of asphalt.
For example, if your parking lot has a gravel base aggregate, it will require a thickness of 7-8 inches, along with an additional 2.5 – 3 inches for the upper layer.
Similarly, the thickness will be different if you are working with a compacted sub-base. The bottom line is that sub base preparation, and the right asphalt thickness is necessary to prevent premature deterioration.
