Paving is the installation of asphalt on base when creating a new parking lot or
overlaying an existing parking lot that is beyond repair.
New Parking Area: When creating a new parking area you must first have a solid base.
Just like building a new house a good foundation is key. Depending on elevation and
other circumstances we dig out to 8 inches below grade on average and haul away.
Next, is to install 6 to 7 inches of base and compact with a vibratory plate or roller.
Finally, install type SIII hot asphalt mix rolled and compacted to 1-1/2” min. For
heavy traffic area 2” would be recommended.
Overlay Existing Area: At this point the asphalt is beyond repair. An overlay is
exactly what it says; we are overlaying the existing asphalt. First, we must remove
all loose material and debris from the area. Then a tack coat is applied, which will
help bond the new asphalt to the existing surface. Hot asphalt mix is rolled and
compacted to a 1” average in most cases. (For heavy commercial vehicle traffic, additional
inch of asphalt should be considered.)
