You want to get your parking lot paved by contractors that specialize in commercial paving in Annapolis, MD. But do you know how the process actually works? Cooper Paving explains the process of asphalt paving. Knowing the steps of the process can help you understand how to take care of your asphalt parking lot better.
1. Demolition of Old Lot
No matter the surface of your existing lot, we’ll have to demolish and remove it. Heavy machinery is used to break up the lot and scoop up the pieces to get rid of them.
2. Sloping and Grading
You want your new lot to be able to get rid of water properly, without it laying in puddles on the asphalt. Water can damage your lot if it doesn’t run off of it in the right way. You may get cracks and potholes forming from water that seeps into the asphalt.
3. Preparing the Sub Base
One of the most important parts of your new asphalt lot is the sub base. It’s laid down and compacted properly to provide a stable base for the asphalt to go over the top. If the sub-base isn’t applied properly, your asphalt lot won’t last as long. The sub-base also protects the asphalt from frost and cold winter temperatures.
4. Apply the Binder Layer
Once we ensure the sub base is sturdy, the binder layer is added. It provides the backbone of your commercial asphalt parking lot. The binder is made up of large aggregate and oil. It’s strong and durable, keeping your lot secure for the long haul.
5. Top it With Fresh Asphalt
The fresh layer of asphalt is made up of sand, small aggregate, and oil. It provides a smooth surface on top of the stronger binder layer. The materials that make up the top asphalt layer create a jet black, smooth surface.
Your lot is most likely connected to a roadway entrance. Your new asphalt and the old asphalt will need a smooth transition between each other so cars don’t get harmed going in and out of the lot. This is called a butt joint and needs to be seamless so drivers don’t notice the difference. It’s especially important to get water runoff and grading right in these areas.
7. One Last Roll
The final roll, using a roller truck, ensures that you have a smooth, even surface. You don’t want any little pieces of aggregate sticking out, as these can pop car tires and cause other harm to cars. This is what gives you the finished product!
