Step one: Removal and Demolition

The first step in the asphalt installation process is usually to get rid of the existing surface, whether it’s asphalt, concrete or perhaps pavers.

Demolition and removal is actually completed using heavy machinery, including small bobcats and forklifts and when necessary, front loaders and large dump trucks.

Debris is then removed.

At Wolf Paving, we recycle the old asphalt and concrete in our asphalt plants, turning deteriorating waste into strong, usable new asphalt. In reality, Wolf Paving typically recycles nearly hundred % of the materials taken from a job site, making the choice to use Wolf Paving both green and environmentally friendly.

Step two: Grading and Sloping

With a thoroughly clean slate, technology helps Wolf Paving’s asphalt professionals prepare the surface area for proper water drainage.

Using laser guided transits and automatic motor graders, the Wolf Paving team grades the surface to be paved to make sure that water will run off appropriately.

Proper water drainage is essential to the asphalt of yours because water is a significant cause of damage, including heaving, cracks, and potholes.

Step three: Prepare the Sub Base

You would never guess that the most important part of your brand new asphalt surface is in fact the sub base.

The sub base provides a stable surface to allow for new pavement.

The sub base is actually a frost barrier to help reduce winter damage due to thawing and freezing.

During the installation, compaction, base stability, and base thickness are essential steps. In the event the sub base is not appropriately compacted, the asphalt surface area on top won’t provide years of durability.

Step four: Proof Roll,  Undercutting and Sub Base Repair

Once the sub base is completely graded and compacted, Wolf Paving completes an additional step, called a proof roll, to make sure the underlying surface is actually ready and strong to support new asphalt.

A Wolf Paving proof roll involves driving a quad axle dump truck, loaded with 72,000 pounds, row by row over the whole area.

If the gravel flexes more than an inch under the weight of the truck, it means that the base isn’t adequately supported.
If the proof roll finds soft areas in the sub base, Wolf Paving makes the necessary repairs in compromised areas to make sure the whole sub base is actually supportive.

Undercutting may be used to repair soft spots. This procedure involves digging down below the surface two or perhaps three feet and replacing the underlying soft clay or perhaps soil with stronger aggregate material.

Wolf Paving also offers alternative options, like using geo grid, rather than undercutting. Using geo grid involves digging only sixteen inches below the surface and laying grid down to bridge base materials together. This creates a good support structure for brand new asphalt at a tiny proportion of the price of traditional undercutting.

Wolf Paving has also pioneered a new process called plowing. This procedure involves undercutting the sub base, but rather than eliminating all the soft clay and soil, it’s instead mixed with added aggregate to boost the power of the compromised areas.

Step five: Binder and Surface Course

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

The binder layer is actually large aggregate mixed with oil, which makes it durable and strong very.

The binder layer can be regarded as the power of any new asphalt surface.

Step six: Install New Asphalt Surface

Once the supportive structures of a new asphalt surface are actually installed, the top-layer of fresh asphalt is actually added to make a fresh, ride that is smooth.

Surface asphalt is actually made up of small aggregate, sand, and oil.

This particular blend of materials creates jet black asphalt that, when installed appropriately, provides a smooth ride and a shiny, attractive finished surface.

Step seven: Butt Joints and Transitions

It’s really rare to install an asphalt surface that doesn’t connect to existing driveways, roadways or perhaps parking lots. As a result, asphalt paving contractors must find a means to smooth the transition from old surface to new.

Butt joints are actually areas where old asphalt or perhaps concrete meets new asphalt pavement.

These transitional areas require particular attention to make sure that the grading and water run off is appropriate.

Butt joints are essential to make sure drivers and pedestrians do not notice a difference in the surfaces.
In order to Complete the Project: Final Roll Once the asphalt and butt joints have been laid, the whole surface is actually smoothed and compacted.

Using a roller truck, the brand new asphalt pavement surface is actually compacted and smoothed.

This process step ensures that no little bumps of aggregate or perhaps stone are actually left poking through the smooth new surface.
Your asphalt paving contractor should follow these installation steps ensure your brand new asphalt surface is going to provide many years of durability and functionally for the house of yours, business, town or city.

But remember that installation process should only follow a good surface inspection and a total estimate. Check out the articles below that explain those processes completely.
