Asphalt surfaces are a popular choice for roads, parking lots, and driveways due to their durability, flexibility, and ease of maintenance. However, to ensure the longevity and performance of an asphalt surface, a good foundation is crucial. In this blog post, we will discuss why your asphalt surface needs a good foundation and the benefits it provides.
IMPORTANCE OF GOOD FOUNDATION FOR ASPHALT
☛ PREVENTS STRUCTURAL DAMAGE
A poor foundation can lead to structural damage to the asphalt surface, such as cracks, potholes, and heaving. When the subgrade is not properly prepared or compacted, it can settle or shift over time, causing the asphalt to crack and deteriorate. A good foundation provides the necessary support and stability to prevent such damage.
☛ EXTENDS THE LIFESPAN OF THE ASPHALT SURFACE
A good foundation can significantly extend the lifespan of an asphalt surface. When the subgrade is prepared and compacted correctly, it can provide a stable and durable base for the asphalt surface. This can prevent premature wear and tear, reducing the need for costly repairs or replacements.
☛ IMPROVES DRAINAGE
A well-prepared subgrade can also improve drainage and prevent water damage to the asphalt surface. When the subgrade is not properly graded or compacted, water can pool on the surface, causing damage and erosion. A good foundation provides proper drainage, directing water away from the surface.
☛ INCREASES SAFETY
A good foundation is essential for ensuring the safety of an asphalt surface. When the subgrade is unstable, it can lead to uneven surfaces, potholes, and other hazards that can cause accidents and injuries. A properly prepared and compacted subgrade can provide a smooth and safe surface for vehicles and pedestrians.
HOW TO ENSURE A GOOD FOUNDATION FOR YOUR ASPHALT SURFACE?
To ensure a good foundation for your asphalt surface, it is essential to hire a professional asphalt contractor with the necessary expertise and equipment. The following steps are typically involved in preparing a good foundation:
- EXCAVATION AND GRADING: The existing soil is excavated, and the subgrade is properly graded to ensure proper drainage and stability.
- COMPACTION: The subgrade is compacted using heavy equipment to ensure proper density and stability.
- BASE COURSE INSTALLATION: A layer of crushed stone or gravel is installed on top of the compacted subgrade to provide additional support and drainage.
- ASPHALT SURFACE INSTALLATION: The final layer of asphalt surface is installed on top of the base course to provide a smooth and durable surface.
