The Complete Crushed Rock Driveway Guide for Denver: Types, Installation, and Maintenance

A crushed rock driveway is a smart fit for Denver homes, offering excellent drainage, durability through freeze–thaw cycles, and a natural look that blends seamlessly with xeriscape landscaping. Unlike paved surfaces, crushed rock allows water to soak into the ground, helping manage stormwater while reducing cracking and long-term repair costs.

This guide explains what makes crushed rock different from standard gravel, which rock types perform best in Denver’s zone 5b–6a climate, realistic costs, and the correct way to install and maintain a long-lasting driveway.

Crushed Rock vs. Gravel: What’s the Difference?

Crushed rock is mechanically processed stone with angular edges and flat faces. These sharp edges lock together when compacted, creating a stable surface that resists shifting under vehicle weight. Gravel, by contrast, forms naturally through erosion and has smooth, rounded edges that roll and slide, making it less suitable for driveways.

Best Types of Crushed Rock for Driveways

Base layers provide structure and load support:

• Crusher run (crush-and-run): A mix of stone and fines that compacts tightly and drains well

• Crushed rock #3 or #4: Larger stones used for heavy-duty bases or added drainage

Surface layers create a smooth, drivable finish:

• Crushed stone #57: Clean, angular, and well-draining

• Crushed stone #411: Includes fines for a firmer, smoother surface

• Decomposed granite (DG): Natural appearance but requires stabilization and more upkeep in freeze–thaw conditions

Pros and Cons of Crushed Rock Driveways

Advantages

• Permeable surface reduces runoff and supports water conservation

• More affordable than concrete or asphalt, especially for long driveways

• Easier DIY installation with forgiving materials

Disadvantages

• Requires periodic raking and topping up

• Snow removal must be done carefully

• Some surfaces produce dust in dry, windy weather

How to Build a Crushed Rock Driveway in Denver

1. Plan and measure the driveway and calculate material quantities

2. Excavate and grade with a slight crown for drainage

3. Install geotextile fabric to prevent soil migration

4. Add and compact the base layer in multiple lifts

5. Spread and compact the surface layer, maintaining slope

6. Install edging and blend the driveway with surrounding landscaping

Cost of a Crushed Rock Driveway in Denver

Material prices typically range from $30–$60 per ton, depending on rock type. Installed costs are usually $2,500–$4,500 for a standard residential driveway, significantly less than concrete. Factors such as size, access, rock choice, and site conditions affect the final price.

Maintenance Tips for Long-Lasting Performance

• Rake and re-level high-traffic areas regularly

• Add fresh surface rock every 2–4 years

• Keep edges and drainage paths clear

• Use gentle snow removal techniques and avoid salt

Conclusion

Crushed rock driveways combine durability, affordability, and natural beauty—making them an excellent choice for Denver properties. With proper installation and routine maintenance, they can perform well for decades while complementing rock gardens and xeriscape designs.
