A high-quality paving job on the parking lot of your commercial facility is essential. A low-quality paving job on your parking lot could allow cracks and other blemishes to develop in your lot quickly. This will detract from the appearance of your company's facility and also frequently require cumbersome and costly repairs.
The following are six key tasks that are required to achieve the utmost quality in a typical parking lot paving job.
Inspection and preparation
Inspecting the lot to begin the paving process is important. During an inspection, a paving contractor will look for any uneven areas of the lot that are collecting standing water after rainstorms.
Also, the contractor will look into any permit requirements put in place in the area's municipality. Many municipalities require a permit before construction work like parking lot paving can begin.
Milling down any faulty areas
A parking lot surface needs to be flat to avoid the collection of water and resulting water damage such as crack development from freeze-thaw cycles.
If surfaces are uneven or parts of the surface are weak, problem areas will need to be milled down. Any existing asphalt needs to be milled down to the subgrade before paving work begins.
Installation of the subbase
For a new parking lot paving job, a subbase will need to be installed. A stable subbase is essential to ensuring a high-quality parking lot paving job.
Subgrade material usually consists of quarry stone, processed concrete, and asphalt. The paving lot contractor needs to evaluate the area and analyze any existing base before formulating the ideal subgrade material mix.
Application of the asphalt surface
After the subbase is installed, asphalt paving should begin. The particular asphalt mix that's ideal for a certain parking lot is determined by factors including the climate and the amount of traffic that the parking lot will be supporting. The asphalt layer needs to be installed uniformly and consistently for a smooth surface.
Use of rollers for compaction
After the asphalt is put down, it is compacted to create a smooth and firm pavement surface. Compacting is done using asphalt vibratory rollers.
Delineating of markers and lines on the surface
The last step of a parking lot paving job is delineating any lines for parking spaces and roadways on the parking lot. Clear and well-marked parking lot lines are important for directing traffic in the parking lot and achieving a professional, orderly appearance at a commercial facility.
