Installing an asphalt parking lot involves several steps to ensure a smooth and durable surface for vehicles. Here is a general rundown of the normal process:

Planning and Design:

Evaluate the site: Assess the area’s condition, soil composition, drainage, and any existing structures that may affect the parking lot layout.

Determine requirements: Consider the expected traffic volume, parking capacity, and any specific needs like ADA compliance or landscaping elements.

Design the layout: Create a plan for the parking lot, including the dimensions, entrances/exits, parking spaces, driveways, curbs, and drainage system.

Site Preparation:

Clear the area: Remove any existing structures, debris, vegetation, or obstacles from the site.

Excavation: Excavate the area to the required depth, considering factors such as soil stability, drainage requirements, and any necessary grading to ensure proper water runoff.

Sub-base Installation:

Sub-grade preparation: Compact the sub-grade soil to create a stable foundation. This may involve removing soft or unstable soil and adding suitable fill materials.

Aggregate base installation: Lay a layer of aggregate (such as crushed stone or gravel) on top of the sub-grade, which provides stability, supports the asphalt, and aids in drainage. The thickness and compaction of this layer depend on the specific project requirements.

Grading and Sloping:

Establish proper slopes: Grade the aggregate base to achieve the desired slope and ensure efficient water drainage away from the parking lot surface and surrounding structures.

Binder Course Installation:

Apply binder asphalt: Spread a layer of binder asphalt (coarse asphalt mix) on top of the graded aggregate base. The thickness of this layer varies depending on the expected traffic load and climate conditions.


Roll and compact: Use heavy rollers or compactors to compress and flatten the binder course, ensuring a stable and well-compacted surface. Adequate compaction is crucial for long-term durability and to minimize future cracks and deformations.

Surface Course Installation:

Apply surface asphalt: Lay a final layer of surface asphalt, also known as the wearing course. This layer consists of a finer mix and provides the smooth and aesthetically pleasing top surface of the parking lot.

Finishing Touches:

Line striping: Mark parking spaces, directional arrows, handicap symbols, and other required signage using traffic paint or thermoplastic materials.

Curb installation: Install curbs, if necessary, to define the edges of the parking lot and assist with drainage.

Curing and Opening:

Allow curing: Depending on the specific asphalt mix used, the parking lot may need time to cure and harden before it can be opened to vehicular traffic. This period typically ranges from a few days to a couple of weeks.

Open for use: Once the asphalt has sufficiently cured, the parking lot can be opened for regular use.

Last Thoughts:

It’s important to note that the actual process and specific steps may vary depending on the project’s size, location, soil conditions, and local regulations. It is recommended to consult with professional asphalt contractors who can provide guidance and ensure the installation is done correctly.
