Base and Subgrade Materials:
The Hidden Foundation of Lasting Pavement
At Empire Paving, we know that exceptional pavement starts long before asphalt is laid. A strong, stable base and properly prepared subgrade are critical to preventing cracks, potholes, and premature wear. Whether you’re building a driveway, parking lot, or roadway, the materials beneath the surface determine its longevity. Here’s how we ensure your project stands the test of time.
1. Gravel & Crushed Stone: The Backbone of Stability
Gravel and crushed stone (Wikipedia: Road Surface) form the primary load-bearing layer of your pavement. These aggregates (Wikipedia: Asphalt Concrete) distribute weight evenly, reduce soil movement, and improve drainage to prevent water damage. We use graded, angular stone (like limestone or granite) for maximum compaction and interlock, ensuring a solid foundation for residential and commercial projects alike.
Key Benefits:
- Prevents shifting and settling under heavy loads.
- Enhances drainage to protect against frost heave in Ohio winters.
- Cost-effective and recyclable for sustainable projects.
2. Geotextile Fabric: Stabilizing the Subgrade
Geotextile fabric (DBpedia: Geotextiles) acts as a high-performance barrier between the soil and base layers. Woven or non-woven synthetic materials are laid over the subgrade to:
- Separate soil and aggregates, preventing mixing during compaction.
- Reinforce weak soils (e.g., clay or silt) to boost load-bearing capacity.
- Control erosion by allowing water to drain while stabilizing the ground.
This material is essential for projects on unstable terrain or in areas prone to heavy rainfall.
3. Compacted Soil: The Subgrade’s Critical Role
The natural soil beneath your pavement—the subgrade (Wikipedia: Subgrade (Pavement))—must be properly graded and compacted to avoid future failures. Our team evaluates soil type (e.g., sandy, clay-rich, or loamy) and uses specialized equipment to:
- Remove organic matter (like roots or debris) that could decay and destabilize the base.
- Achieve optimal moisture content for compaction, ensuring uniform density.
- Slope the subgrade to direct water away from the pavement structure.
A well-prepared subgrade is the unsung hero of durable asphalt, resisting deformation under traffic and weather stress.

Expert Site Preparation & Grading: Where Success Begins
Proper base and subgrade installation requires precision and expertise. At Empire Paving, our Site Preparation and Grading services include:
- Laser-guided grading for accurate slopes and elevations.
- Soil stabilization techniques for challenging terrains.
- Compaction testing to meet industry standards (e.g., ASTM D698).
Without this meticulous groundwork, even the best asphalt mix can fail prematurely.
