Glossary of Paving Terminology

Paving projects can sometimes feel overwhelming, especially with the technical terms involved. You may find yourself nodding along to words like “aggregate” or “seal coat,” but not fully understanding what they mean. That’s perfectly okay—we’ve all been there. To help you feel more confident and in control of your project, we’ve created this glossary of paving terminology.

The Importance of Understanding Industry Terms

Our goal is not to overwhelm you with information. However, having a basic understanding of key terms can make it easier to communicate your needs and stay informed throughout the project. Being knowledgeable allows you to feel more confident and equipped to ask the right questions.

For example, understanding the difference between “patching” and “milling” can help you make more informed decisions when choosing between repair options or discussing your project with a contractor.

A Guide to Common Paving Terms

Aggregate

Aggregate refers to crushed stone, gravel, or sand used in asphalt mixtures. It is the foundation of your pavement, helping it stay strong and durable.

Asphalt Overlay

An asphalt overlay is a layer of new asphalt applied over existing pavement. It is a cost-effective way to improve the surface without completely tearing it out. Overlays are fantastic for parking lots and driveways that need a refresh.

Base Course

The base course is the layer beneath the asphalt. It has compacted aggregate and acts as the support system for the pavement above. Without a solid base, the surface will not last.

Crack-Filling

Crack-filling involves sealing small cracks to prevent water from entering and causing more damage. It is a simple way to keep pavement in good shape for longer.

Milling

Milling is the process of removing the top layer of asphalt. This creates a smooth, even surface for new paving.

Seal Coating

Seal coating adds a protective layer to asphalt. It helps shield the surface from weather, UV rays, and regular wear and tear. It also gives the pavement a fresh, clean look.

Subgrade

The subgrade is the soil beneath the pavement. It needs to be stable and well-prepared before paving begins. If the subgrade is not right, the pavement can crack or sink over time.

Pothole Patching

Pothole patching fills holes caused by wear, water damage, or freezing and thawing cycles. It is a quick fix to improve safety and appearance.

Striping

Striping refers to the painted lines on parking lots or roads. Clear, crisp striping is key for safety and organization.

Drainage

Drainage is the system that directs water away from the pavement. Good drainage prevents pooling, which can weaken the surface and cause cracks.
