Grading involves creating a stable, level foundation by shaping the ground to optimise water drainage and support the asphalt layer. It ensures that the road has a smooth, uniform surface and provides a solid base capable of withstanding heavy loads. By establishing the correct slope and ground conditions, grading sets up an asphalt surface that can resist the forces of nature, including water flow and temperature shifts, both of which can cause significant wear on ungraded or poorly graded surfaces.
How Grading Prevents Soil Erosion
Soil erosion occurs when water runs over the ground, loosening and carrying away soil particles. Without proper grading, this erosion can compromise the ground under an asphalt surface, leading to cracks, potholes, and even collapse over time. Here’s how grading effectively prevents soil erosion:
- Directs Water Flow: Grading is essential for directing water away from the road surface. By angling the foundation correctly, water is channelled to designated drainage areas, preventing it from accumulating and causing erosion.
- Stabilises the Ground: Proper grading compacts and stabilises the soil beneath the asphalt, making it less prone to shifting. Stable ground provides a firm base for the asphalt, preventing cracks and surface damage caused by shifting soil.
- Reduces Erosion Risk: By establishing a slope that directs water efficiently, grading reduces the risk of erosion around the edges and beneath the asphalt surface, where erosion is otherwise likely to go unnoticed until major repairs are needed.
How Grading Protects Asphalt Surfaces
Effective grading not only prevents erosion but also protects the asphalt surface itself. An asphalt surface laid on well-graded ground will better resist the stresses of vehicle traffic, temperature changes, and weathering. Here’s how grading supports asphalt durability:
- Prevents Cracking and Potholes: A well-graded foundation minimises the risk of water pooling on the asphalt surface. Standing water is a significant factor in asphalt cracking, as it seeps into small cracks, freezes, and expands, widening the damage over time. Proper grading directs water off the surface, reducing the formation of cracks and potholes.
- Maintains Asphalt Strength: An asphalt layer is only as strong as the foundation beneath it. Grading provides a stable and evenly distributed base, preventing the formation of weak spots where the asphalt may break down prematurely.
- Improves Surface Longevity: When grading is executed correctly, it ensures that the asphalt surface remains level and intact, reducing maintenance costs and prolonging the lifespan of the road.
