When planning to pave a new asphalt driveway, choosing the right base material is crucial for the longevity and durability of the pavement. The base layer not only supports the asphalt but also ensures proper drainage, compaction, and overall stability. This comprehensive guide will answer the question, “What is the best base for an asphalt driveway?” and help you make an informed decision for your next paving project.
What Base Is Needed for Asphalt?
The base for an asphalt driveway must provide a stable foundation, proper drainage, and sufficient compaction. There are several types of base materials to consider, each with its advantages and best-use scenarios. The most common base materials include crushed stone, gravel, and sand.
Key Questions to Consider:
- What type of traffic will the driveway support?
- What are the local weather conditions?
- What is the soil composition of the site?
What to Put Under Asphalt?
Under the asphalt, a well-prepared base layer is essential. The base material should be carefully selected and properly installed to ensure a durable and long-lasting pavement. Crushed stone and gravel are popular choices due to their stability and drainage properties.
Types of Base Materials:
- Crushed Stone: Provides excellent drainage and stability.
- Gravel Base: Offers a firm surface and good load-bearing capacity.
- Sand: Suitable for certain conditions but less common due to its lack of stability compared to stone and gravel.
What is the Best Base Layer for a Driveway?
The best base layer for an asphalt driveway depends on several factors, including climate, soil type, and traffic load. However, crushed stone is often considered the best base material due to its ability to drain well and provide a stable foundation.
Benefits of Crushed Stone:
- Superior drainage properties
- High stability and compaction
- Effective in preventing weeds and vegetation growth
How to Build a Base for an Asphalt Driveway?
Building a base for an asphalt driveway involves several critical steps to ensure proper compaction, grading, and drainage. Follow these steps for a robust and durable base layer:
- Excavation: Remove the topsoil and any organic material to reach a stable subgrade.
- Grading: Grade the area to ensure proper drainage away from structures.
- Compaction: Compact the subgrade using a vibratory roller to achieve a firm base.
- Base Material Installation: Spread the chosen base material, such as crushed stone or gravel, in layers.
- Layer Compaction: Compact each layer of base material thoroughly before adding the next layer.

A good base layer for asphalt must meet the following criteria:
- Stability: The base should be stable to support the asphalt and prevent shifting.
- Drainage: Proper drainage is essential to prevent water accumulation, which can damage the pavement.
- Compaction: The base material should be compacted to provide a solid foundation for the asphalt.
Recommended Base Materials:
- Crushed stone for stability and drainage
- Gravel for load-bearing capacity and ease of compaction
What is the Best Base Material for Driveway?
