Have you ever driven past a freshly paved parking lot and wondered what it takes to make one? From start to finish, there are a few important steps involved in the construction of a parking lot.
Here's a closer look at what the process entails.
Planning and Prepping
Before any construction work can begin, careful planning and prepping need to happen first. This includes surveying the lot and determining the size, shape, and layout that will work best for your space. The layout must also account for the number of parking spaces needed, any landscaping elements, and any other design features you may want included.
Then comes soil testing, which helps the experts determine if additional layers of material are required for proper drainage. Some soil may need to be replaced with gravel or decomposed granite to ensure rainwater can adequately drain away from the parking lot surface.
Once the surveying and testing are complete, it's time to establish the parameters of the lot. This includes marking off boundaries and setting up a framework with stakes and strings to define the shape. This plan follows the local codes and regulations, which vary based on the location.
Excavation
Once all the necessary planning is complete, it's time for excavation. This step involves removing existing vegetation or debris from the site as well as digging up the soil to create a level surface for paving. Usually, the contractor has to take care not to disrupt any existing underground utilities. They have to mark off those utilities and have a plan in place to protect them while the excavation is taking place.
It's also important to check below ground level for rocks or other hidden debris during this step. If these things are not moved before the pavement is laid, they can cause bumps and cracks in the surface.
Paving
This is where things really start coming together. Once the site is cleared and leveled out, asphalt is applied in layers using specialized paving machines. Asphalt gets compacted between each layer using heavy rollers. This step helps ensure that no air pockets are left behind and creates a smooth, even surface when finished.
During this step, you may also want to consider adding lines or markings like crosswalks or arrows to direct traffic flow through your lot. The lines have to be symmetrical and spaced evenly so that vehicles can properly maneuver through the parking lot.
The last step is seal coating. Sealing your asphalt helps keep moisture out of your pavement, so it will last longer with less maintenance required over time. The process is quick and has to be done right after the paving is finished so that the sealant adheres to the asphalt.
