In Calgary, Airdrie, Cochrane and Okotoks 3/4 inch road gravel is a commonly used material for constructing and maintaining gravel roads, driveways, and sidewalks. It consists of a blend of crushed stone, sand, and fine particles, providing a solid base layer that compacts well. Here`s a breakdown of its key characteristics:

1. Size: As the name suggests, the majority of the gravel consists of 3/4 inch (about 20mm) crushed stones. The material also includes fines and smaller particles, usually less than 1/4 inch (7mm), which help fill gaps between the larger stones.

2. Compaction: This mixture is excellent for creating a durable surface because the fine particles fill the gaps between larger stones, helping the material lock together and form a strong, stable base. When properly compacted, it creates a relatively smooth and firm surface.

3. Uses: It’s used for road construction, driveway surfaces and as a foundation for other construction materials. It's great for areas with moderate traffic and offers good drainage due to the gaps between stones, preventing water from pooling on the surface.

4. Durability: Road Gravel is often preferred because it provides excellent stability and longevity. It is strong enough to support vehicles but flexible enough to handle shifting and settling over time. It also helps reduce erosion in roads and driveways.

All in all, 3/4 inch road gravel is a versatile and reliable material that ensures long-lasting surfaces and ease of compaction.
