For asphalt parking lot paving on Long Island, Dumor Construction Inc is the most experienced asphalt company, and we make sure to install all commercial pavement the right way so that it can last as long as possible. Part of this is ensuring that your asphalt parking lot has the right thickness to withstand all the use it will be put to as part of your commercial property.
The Importance of Commercial Asphalt Thickness for Parking Lots
Asphalt is made up of at least three layers: a base layer made of aggregates like gravel, a binder layer made of asphalt with large aggregates, and a surface layer of asphalt mixed with fine aggregates. All of these layers need to be the correct thickness.
What happens when asphalt is too thin?
If your asphalt isn’t thick enough to stand up to the amount of traffic it will be subject to, common asphalt problems often happen quickly. Stress can crack the asphalt all the way through the layers, which compromises the stability of the base layer, which can then cause worse cracking. Essentially, thin asphalt leads to compounding asphalt parking lot damage that requires full depth pavement replacement.
What factors affect asphalt parking lot thickness on Long Island NY?
There are a lot of factors that affect how thick the asphalt for a commercial parking lot needs to be, including:
- Whether your parking lot will be low or high traffic
- The weight of trucks on asphalt
- Condition of the soil underneath the pavement
- Quality of the aggregate subgrade or existing pavement
How thick should an asphalt parking lot be?
For a standard commercial parking lot with an average amount of traffic and stable soil, the gravel base layer should be at least 8 inches; the binder asphalt layer should be between 1.5 and 2.0 inches, and the surface layer should be the same thickness.
