Our expert asphalt contractors have all the knowledge of modern paving processes and all the latest technologies to create perfectly smooth, durable driveways. Our commitment to quality permeates every step of the driveway paving process. But what are those steps? Let’s take a look.

Step 1: Demolition

To make sure your new asphalt driveway will last for years, you need a clean slate. The first step is removing any existing paving and debris. Asphalt is also recyclable, so we can reuse this asphalt in an environmentally friendly process that saves money too!

Step 2: Grading

The leading cause of asphalt damage is water, which can break down your driveway if it’s not allowed to run off. That’s why we professionally grade the driveway area to ensure proper drainage.

Step 3: Sub-Base

This step provides a durable base layer as well as a frost barrier to prevent asphalt damage from freezing and thawing. The soil is compacted with heavy machinery like a roller to create a stable base for the driveway.

Step 4: Binder

Called a binder or “surface course,” this layer is crushed rock mixed with oil that provides strength for the asphalt layer. The rough texture of crushed rock helps the smoother surface asphalt stick. Once applied, this layer is pressed down into the sub-base layer with a heavy roller.

Step 5: Asphalt

After the base layers have been properly applied, compacted, and graded, it’s time for the asphalt to be applied. Asphalt is fine aggregate such as sand mixed with bitumen, a crude oil product. The asphalt is poured hot over the binder layer, then allowed to cool to create a shiny, black surface.

Step 6: Connect

Next, the new asphalt driveway needs to be connected seamlessly with other paved areas such as concrete sidewalks or asphalt roadways. These transition spaces are important to prevent accidents and provide adequate drainage.

Step 7: Compact

A heavy rolling machine rolls over the asphalt as it cools to press it down into a perfectly level, smooth layer. The last step ensures that the asphalt surface is smooth and perfect, without any bumps or imperfections that can lead to damage later on.
