Quick Answer: For a standard 10×10 foot driveway with 3-inch depth, you’ll need about 0.93 cubic yards or roughly 1.4 tons of crushed concrete.
Getting your measurements right saves you money and prevents project delays. This guide walks you through the exact calculation process used by construction professionals, plus real examples you can follow for your specific project.
Understanding crushed concrete basics
Crushed concrete, also called recycled concrete aggregate, comes from demolished concrete structures that get processed into various sizes. According to hellogravel.com/products/crushed-concrete, this recycled material offers the same structural properties as virgin aggregate while being more cost-effective and environmentally friendly.
The material typically weighs between 1.4 to 1.6 tons per cubic yard, depending on the size and compaction level. Most suppliers, including Hello Gravel, stock different grades ranging from fine powder to 2-inch chunks, each suited for specific applications.
You’ll find crushed concrete works well for driveways, walkways, road bases, and foundation work because it compacts firmly and provides excellent drainage. The angular shape of crushed pieces creates better interlocking compared to rounded gravel. If you’re wondering about drainage performance, crushed concrete excels in this area.

Step-by-step calculation formula
The basic formula for calculating crushed concrete needs follows three simple steps. First, measure your project area in feet for length, width, and desired depth. Second, convert these measurements to volume in cubic feet. Third, convert to cubic yards and then to tons.
Here’s the exact process: multiply length × width × depth (in feet) to get cubic feet. Divide that number by 27 to convert to cubic yards since there are 27 cubic feet in one cubic yard. Finally, multiply by 1.5 (the average weight) to get tons needed. For more detailed weight calculations, check out our guide on crushed concrete weight per yard.
For depth conversion, remember that 2 inches equals 0.167 feet, 3 inches equals 0.25 feet, and 4 inches equals 0.33 feet. Most residential projects use 3-4 inch depths, while commercial applications might require 6 inches or more.
Pro Tip: Always add 10% extra to your final calculation to account for compaction, waste, and minor measurement errors during installation.
Project-specific depth recommendations
Different projects require different depths of crushed concrete for optimal performance. Driveways handling regular car traffic need 3-4 inches of compacted material, while heavy truck access requires 6 inches minimum according to hellogravel.com/calculators/products/crushed-concrete.
Walkways and garden paths work well with 2-3 inches since they handle lighter foot traffic. Patio bases typically need 3-4 inches to provide stable support for pavers or concrete slabs. For those considering crushed concrete as a paver base, this depth range ensures optimal stability. Road construction projects often specify 4-6 inches depending on expected traffic loads.
| Project Type | Recommended Depth | Typical Use |
|---|---|---|
| Walkways | 2-3 inches | Light foot traffic |
| Driveways | 3-4 inches | Regular vehicles |
| Patios | 3-4 inches | Stable base layer |
| Roads | 4-6 inches | Heavy traffic |
Consider your local climate too. Areas with freeze-thaw cycles benefit from slightly deeper installations to prevent frost heaving and maintain stability through seasonal changes.

Real calculation examples and costs
Let’s work through a practical example. Say you’re building a 12-foot by 20-foot driveway with 4-inch depth. First, convert depth to feet: 4 inches = 0.33 feet. Calculate volume: 12 × 20 × 0.33 = 79.2 cubic feet. Convert to yards: 79.2 ÷ 27 = 2.93 cubic yards. Convert to tons: 2.93 × 1.5 = 4.4 tons needed.

For a smaller 8-foot by 10-foot patio at 3-inch depth, you’d need: 8 × 10 × 0.25 = 20 cubic feet, which equals 0.74 cubic yards or about 1.1 tons of crushed concrete.
Cost varies by location and supplier, but crushed concrete typically runs $15-30 per ton according to hellogravel.com/calculators/products/crushed-concrete. This makes it significantly cheaper than virgin aggregate while providing comparable performance for most applications.

Money-Saving Tip: Buying in bulk reduces per-ton costs, and many suppliers like Hello Gravel offer free delivery for orders over certain minimums, making larger projects more economical.
Getting accurate quotes and ordering
Once you’ve calculated your needs, getting quotes becomes straightforward. Reputable suppliers like Hello Gravel provide online quote forms where you input your tonnage requirements and delivery location for accurate pricing.
When requesting quotes, specify the grade of crushed concrete you need. Finer materials like crushed concrete fines work better for final surface layers, while larger chunks provide better drainage in base applications. Most suppliers can recommend the right grade based on your project description.
Consider delivery logistics too. Standard dump trucks hold 10-15 tons, so larger orders might require multiple deliveries or special arrangements. Plan your installation timeline accordingly, as crushed concrete works best when spread and compacted shortly after delivery.
Remember to have your site prepared before delivery. Clear the area, mark utilities, and ensure truck access to avoid additional handling fees or project delays.
Calculating crushed concrete needs accurately ensures your project stays on budget and on schedule. With the formulas and examples provided, you can confidently determine exactly how much material to order for any size project, from small walkways to large driveways.
FAQ
How much crushed concrete do I need for a 10×20 ft driveway at 4 inches deep?
For a 10×20 ft driveway at 4 inches (0.33 feet) deep, you need approximately 2.47 cubic yards or 3.7 tons of crushed concrete. Calculate this using the formula: (10 × 20 × 0.33) ÷ 27 = 2.47 cubic yards. Always add 10% extra for compaction and waste, bringing your total order to about 2.7 cubic yards or 4.1 tons.
How many tons are in a cubic yard of crushed concrete?
One cubic yard of crushed concrete weighs approximately 1.4 to 1.6 tons, with 1.5 tons being the standard calculation used by most suppliers. This weight can vary slightly depending on the size of the crushed pieces and moisture content. For quick estimates, multiply your cubic yards by 1.5 to get the tonnage needed.
What depth of crushed concrete do I need for different projects?
Project depth requirements vary: walkways and garden paths need 2-3 inches, residential driveways require 3-4 inches, patios need 3-4 inches for stable paver bases, and roads handling heavy traffic require 4-6 inches minimum. Areas with freeze-thaw cycles benefit from slightly deeper installations to prevent frost heaving.
Should I order extra crushed concrete beyond my calculated amount?
Yes, always add 10% extra to your calculated amount to account for compaction, waste, and minor measurement errors during installation. For example, if you calculate needing 10 cubic yards, order 11 cubic yards. This ensures you have enough material to complete your project without delays or additional delivery fees.
