Asphalt is one of the most popular materials used for surfacing roads, driveways, and parking lots due to its durability, flexibility, and cost-effectiveness. However, to ensure that asphalt surfaces maintain their integrity and continue to perform well over time, regular maintenance is essential. One of the most important maintenance tasks is grading, which plays a key role in preventing asphalt deterioration. In this blog post, we’ll explore how grading helps protect your asphalt surface and why it’s crucial for long-lasting results.
What is Grading and Why is It Important?
Grading refers to the process of reshaping and levelling the ground beneath the asphalt surface. It’s the first step in the construction of a new asphalt roadway or driveway and also an important part of maintaining an existing surface. Proper grading helps ensure that water drains away from the surface, that the base is level, and that the asphalt can properly adhere to the ground beneath it.
Key Benefits of Grading
- Prevents Water Accumulation: One of the main causes of asphalt deterioration is water pooling on the surface. Without proper grading, water can collect on low points, seeping into the asphalt and causing cracks, potholes, and other forms of damage. By grading the surface correctly, water is directed away from the asphalt, minimising the risk of water-related deterioration.
- Improves Drainage: Effective grading ensures that your asphalt surface has proper slope and drainage, helping to maintain its structural integrity. Poor drainage can result in moisture infiltration, weakening the asphalt and making it more susceptible to damage from weather conditions and heavy traffic.
- Enhances Longevity: By addressing drainage issues and creating a solid, even foundation, grading helps prevent the kinds of wear and tear that lead to premature asphalt failure. This ultimately extends the lifespan of your asphalt surface and reduces the need for costly repairs or replacements.

The Link Between Grading and Asphalt Deterioration
Asphalt deterioration occurs when the surface begins to break down, crack, or deform due to a variety of factors, including moisture, heat, and traffic. Without proper grading, these issues can become exacerbated, resulting in quicker wear and damage to your asphalt surface.
How Grading Prevents Deterioration
- Avoids Uneven Surfaces: Proper grading ensures that the asphalt is laid on an even, smooth surface. Without it, the asphalt may settle unevenly, causing weak spots that are more prone to cracking and deterioration.
- Reduces Stress on the Asphalt: When water is unable to drain properly, it can seep into the base material and cause it to shift, leading to surface cracking. Regular grading helps maintain a stable, supportive base that prevents this from happening, reducing stress on the asphalt surface.
- Minimises Soil Erosion: Grading also helps minimise soil erosion underneath the asphalt. Erosion can create voids that weaken the structure of the surface, making it more likely to crack or shift. By ensuring proper grading, the risk of erosion is greatly reduced.
Regular grading helps ensure that your asphalt surface remains strong, level, and protected from the elements, preserving its functionality for years.
How Often Should Grading Be Done?
The frequency of grading depends on several factors, such as traffic volume, weather conditions, and the type of asphalt. For most residential driveways and small commercial surfaces, grading should be done every 1-3 years to maintain optimal performance. In areas with heavy traffic or frequent weather extremes, more frequent grading may be required.
Signs That Grading is Needed
- Water Pooling: If you notice that water is pooling in certain areas of your asphalt surface, it’s time to consider grading. Poor drainage is one of the leading causes of asphalt deterioration.
- Visible Cracks or Potholes: Uneven grading can lead to the formation of cracks or potholes in your asphalt. These can worsen over time if not addressed promptly.
- Uneven Surface: If your asphalt surface appears uneven or bumpy, it could indicate that the grading underneath is no longer effective.
