Asphalt Thickness Calculator – What’s The Minimum Thickness Of Asphalt Paving?

asphalt thickness calculatorPlanning to repave your driveway or commercial parking lot? Asphalt thickness is one of the most common areas of question and uncertainty. Many homeowners and commercial property owners just don’t know the best thickness. Deterioration can occur if your asphalt is laid too thin or too thick. The asphalt thickness calculator scale will vary for residential driveways vs. commercial properties.

There is also an appropriate asphalt calculator scale for the thickness of the base. Even asphalt installed at an appropriate thickness will fail if the base is too thin or if laid improperly.

So how do you know what asphalt thickness is appropriate for your project? Let’s start with the base.

  • A residential base is constructed of 6-8”of granular base aggregate. The base is then compacted and installed on top of the subgrade.
  • A standard commercial lot will require an aggregate layer of 8”.
  • The appropriate asphalt thickness calculator for a commercial base will vary. One factor that contributes is how much traffic. Also, the type of traffic.

Is 2 Inches Of Asphalt Enough For A Driveway?

After the 2” binder layer of your commercial lot, you will need a 1.5” thick layer of smoother compacted asphalt. This is a total of 3” thickness. However, heavy duty traffic lots should get at least a 2” layer of asphalt in addition to the binder. For a total of 4” asphalt thickness.

What If My Asphalt Is Too Thin?

If asphalt is too thin, weight will not be distributed appropriately. This will cause compression of the material under a tire. This will often result in premature fatigue cracking. Resulting in a structurally compromised pavement.

Issues To Damaged Asphalt

If your asphalt thickness is incorrect, you will see issues quickly.

  • Cracking asphalt
  • Stripping is the debonding of aggregate and binder
  • Rutting is surface depression alone wheel path
  • Failure is the loss of adhesive between layers

Firstly, you can ensure that your pavement does not deteriorate prematurely with proper installation. As part of the installation process you want to not only make sure that asphalt thickness is appropriate for the situation but also that base installation and thickness is correct. Following proper installation, regular maintenance and repairs are key. By maintaining and repairing asphalt, you can ensure your investment lasts as long as it should. Well-maintained asphalt should last 15-30 years.
