Asphalt Roads & Parking Lot Installation

Asphalt Installation

Trusted Asphalt Installation & Site Prep

When it comes to asphalt installation, be it for roads, driveways, or parking lots, the most crucial step is ensuring the foundation is meticulously excavated and compacted. At KGW Corporation, we pride ourselves on our extensive experience and expertise in excavation and compaction, ensuring the success of every project.

The Importance of Proper Foundation Preparation

Before beginning any asphalt installation project, it is crucial to prepare the foundation properly. This involves excavating and compacting the area where the asphalt will be laid. The quality and stability of the foundation directly impact the durability and longevity of the asphalt surface.

Excavation

Excavation refers to the process of removing soil or other materials from an area for construction purposes. In terms of asphalt installation, this means removing any existing pavement or debris from the designated area. Proper excavation ensures that there is enough space for proper layering and compaction later on in the process.

The depth of excavation will depend on the specific project and the type of pavement being installed. For example, a road will require deeper excavation compared to a driveway or parking lot due to the expected traffic load.

Compaction

Compaction is the process of mechanically compressing soil and other materials to increase its density and strength. In terms of asphalt installation, this means compacting the foundation material to create a sturdy base for the asphalt. This step is crucial as it ensures that the foundation can withstand heavy loads and prevents future cracking or settling.

There are several methods of compaction, including using rollers or compactors, depending on the size and type of project. The compaction process is repeated multiple times to achieve the desired level of density.

Binder and Surface Course  

Once the sub-base is laid and any soft areas are identified and repaired, it is time to add the binder.

• The binder layer is a large aggregate mixed with oil, making it very strong and durable.
• The binder layer can be thought of as the strength of any new asphalt surface. 

Installing a New Asphalt Surface

After setting up the foundational structures for a new asphalt surface, the final layer of asphalt is laid down to ensure a smooth and clean ride.

• The surface asphalt consists of small aggregate, sand, and oil.
• This blend results in jet-black asphalt that, when properly installed, offers a smooth ride and an attractive, shiny finish.

Butt Joints and Transitions

Installing an asphalt surface that doesn’t connect to existing driveways, roadways, or parking lots is a rare occurrence. Therefore, asphalt paving contractors must ensure a seamless transition from the old surface to the new one.

• Butt joints are where old asphalt or concrete meets new asphalt pavement.
• These transitional areas need meticulous attention to ensure proper grading and water run-off.
• Ensuring smooth butt joints is crucial so drivers and pedestrians do not notice a difference between surfaces.

Finally, Final Roll

Once the asphalt and butt joints are laid, the entire surface is smoothed and compacted to ensure optimal quality.

• A roller truck is used to compact and smooth the new asphalt pavement.
• This crucial step ensures that no small bumps or aggregates remain, resulting in a perfectly smooth surface.
