Key Factors to Think About Before Choosing an Asphalt Overlay

Asphalt overlays are often a great solution for improving the surface of parking lots, driveways, and roadways. For both residential and commercial properties, they offer a cost-effective way to extend the lifespan of existing pavement. As an asphalt company, we’ve seen firsthand that the effectiveness of an overlay depends on several key factors—like the current condition of the pavement, how much preparation is required, and the long-term durability of the new surface.

If you’re considering an asphalt overlay for your property, here are the top things to think about:

1. Elevations and Drainage

Proper drainage is essential when performing an asphalt paving overlay. Before applying the new layer, the existing pavement must have the correct elevations to ensure water drains efficiently. If the surface is too high, sections may need to be sawcut and removed so the overlay sits flush with nearby areas like building aprons, garages, or sidewalks. A well-graded asphalt driveway or parking lot ensures surface water won’t pond and cause premature wear.

2. Existing Grade of the Surface

An asphalt overlay will follow the current grade of the surface. That’s why it’s crucial to evaluate slope and drainage before starting. If the existing pavement has poor slope, it can lead to standing water, cracking, or erosion. A paving company should assess the site thoroughly to make sure the grade is working for—not against—the new overlay.

3. Existing Cracking

Cracks in the pavement tell a story. Structural cracks often point to deeper base issues that a surface overlay alone can’t fix. In these cases, asphalt repair or partial reconstruction may be necessary before paving. Minor cracks from surface aging or wear can typically be paved over, but if they signal a failing base, an asphalt overlay may not be the right solution. A thorough inspection by an asphalt contractor will help determine what’s best.

4. Long-Term Expectations

An asphalt overlay is ideal when the pavement has minimal cracking, stable drainage, and a solid base. It’s a great way to refresh your asphalt driveway or lot without the expense of full removal and replacement. Keep in mind that reflective cracking from the original surface may appear over time—but when installed correctly, an overlay can significantly extend the pavement’s lifespan and enhance its appearance.
