Can my new asphalt parking lot go over my existing concrete parking lot?
When you work in commercial asphalt like Goodmanson Construction does, you get a lot of questions aimed at trying to get costs down. One of the ways that people try to get costs down is putting a new surface over an older surface.
The answer is that yes it’s possible to do, but no we do not recommend it. The least we recommend is a mill and overlay, depending on the kind of surface you have.
If you already have an asphalt parking lot, but it needs some real work: Mill and Overlay is a good cost-effective solution.
If you don’t want to get into the subgrade and do excavation, and you don’t have a lot of material down already, you can save money on quality asphalt paving by going for a mill and overlay.
Mill and overlay is when we take a machine that runs over your current asphalt surface and “mills” it by grinding it back up into crushed rocks. After that process, you have an asphalt overlay of fresh pavement.
Parking Lot Installation is More than Just Asphalt Paving: It Starts from the Ground Up.
If you lay asphalt over concrete, what you sacrifice is control over the sub-grade surface. You lose control over the composition of it and the depth of it. Sub-grade material is one of the most important elements of a parking lot that will withstand the test of time.
If you just pave asphalt over concrete, you also run into the problem of the concrete control joints. We cut control joints into concrete in order to “control” the way that concrete naturally moves, expands and contracts over time. Paving asphalt over the control joints just means that now those joints are going to expand and move underneath the asphalt, which could cause damage to the surface.

How do you want people to use the parking lot? How do you want people to access it? What kind of traffic do you expect? How long do you want it to last and under which weather conditions?
