When it comes to building and maintaining durable roads, one crucial step is often overlooked: grading. Grading is the process of levelling and preparing the road surface before laying asphalt or bitumen. While most people are familiar with asphalt surfacing and repairs, grading is the foundational step that ensures the longevity of a road and protects it from future damage, including potholes. At Coburg Road Tech, we understand that proper grading is key to creating smooth, durable roads that stand the test of time in Coburg, VIC, and surrounding areas.
In this blog post, we’ll explain why grading is so important and how it helps prevent potholes, saving you time and money in the long run.
What is Grading?
Grading involves shaping the base of the road by removing uneven surfaces, compacting the soil, and ensuring proper drainage. This step sets the stage for laying asphalt or bitumen, creating a stable foundation that supports the road surface and prevents future issues like cracking or sinking.
The quality of grading directly impacts the durability of the road. Without proper grading, even the best asphalt or bitumen surface will eventually develop potholes and cracks as the underlying base shifts or deteriorates.
How Grading Protects Roads from Potholes
- Creates a Solid Foundation Potholes often form when the base beneath the road becomes unstable. Poorly graded roads may have pockets of air or loose soil that cause the surface to collapse over time. By thoroughly grading the area before asphalt application, we ensure that the road has a solid, compact foundation. This prevents the base from shifting and causing surface failures like potholes.
- Improves Water Drainage One of the primary causes of potholes is water penetration. When water seeps into cracks and collects under the surface, it weakens the base layers, leading to erosion and eventual pothole formation. Proper grading addresses this issue by ensuring the road is sloped in a way that allows water to drain away, rather than pooling on the surface. This reduces the likelihood of water damage, keeping the road intact for longer.
- Prevents Erosion Erosion is another major contributor to pothole formation. Roads that aren’t graded properly can experience erosion due to wind and water flow, which weakens the base and leads to the breakdown of the surface. Grading helps by ensuring that the soil is compacted and stable, preventing it from being washed away during heavy rainfall. A well-graded road is less susceptible to erosion and the subsequent potholes that can follow.
- Enhances Surface Longevity When roads are graded correctly, the asphalt or bitumen layer on top remains even and smooth for a much longer period. A poorly graded base can lead to uneven weight distribution, which causes stress on certain areas of the road, leading to cracks and potholes. By creating a level and supportive base, grading helps the surface wear evenly, extending the lifespan of the road and reducing the need for frequent repairs.
- Cost-Effective Maintenance Proper grading is an investment that can save significant costs over the lifespan of a road. Roads that are graded well from the outset require fewer repairs, as they are less likely to develop potholes or other forms of damage. This reduces the need for costly resurfacing or patching down the line, making grading a cost-effective solution for long-term road maintenance.
