Best Gravel for Driveways
In this video Doc explains the best gravel for driveways. After building roads mostly from scratch, Doc has finally realized that Crush and Run is by far the best choice for solid gravel roads.

More Info on Driveway Gravel
Crusher run (also known as crush and run or quarry process) is a popular aggregate material for gravel driveways, consisting of crushed stone mixed with stone dust or fines (typically ranging from 3/4-inch pieces down to silt-sized particles). It’s often preferred over standard loose gravel (like pea gravel or rounded river rock) because of its unique composition, which allows it to form a more stable, durable, and low-maintenance surface.

Superior Compaction and Stability
The fines in crusher run act as a “binder” when compacted, filling voids between the larger angular stones and creating a semi-solid, hard-packed surface that locks together. This prevents the material from shifting, rutting, or spreading under vehicle weight, which is a common issue with loose gravel that has rounded stones and no fines.
In contrast, standard gravel tends to displace easily, requiring frequent regrading or adding more material. Crusher run forms a stable base that supports heavy loads (e.g., cars, trucks) without sinking or forming potholes, making it ideal for driveways with regular traffic.

Better Load-Bearing Capacity and Durability
The angular shape of the crushed stones interlocks tightly, providing excellent structural integrity and resistance to wear from tires or weather. It’s commonly used as a base layer for roads, patios, and even under asphalt or concrete, but it works well as a standalone surface for gravel driveways.
Loose gravel lacks this interlocking, leading to quicker breakdown, erosion, or mud formation in wet conditions. Crusher run withstands freeze-thaw cycles better in colder climates by not holding excess moisture, reducing the risk of cracking or heaving compared to non-permeable surfaces like concrete.

Improved Drainage While Preventing Erosion
Despite compacting densely, crusher run remains permeable, allowing water to drain through the voids rather than pooling on the surface. This reduces hydroplaning risks and prevents water damage to the underlying soil.
It also controls erosion effectively by stabilizing the soil and channeling runoff, especially on sloped driveways. Standard gravel can wash away fines or create channels during heavy rain, leading to uneven surfaces and more maintenance.

Cost-Effectiveness and Low Maintenance
Crusher run is typically cheaper than alternatives like asphalt or concrete (around $0.50–$2 per square foot installed), and it’s more affordable than washed or decorative gravels while offering better longevity. Once compacted, it requires minimal upkeep—occasional raking or topping off every 1–2 years—versus constant replenishment needed for loose gravel that migrates off the edges.
It’s also versatile for DIY installation: spread in layers (4–6 inches thick), grade for proper slope, and compact with a roller or vehicle. This makes it a practical choice for rural or budget-conscious homeowners.
