Is crushed concrete better than gravel? Crushed Concrete driveways are a much more cost-effective driveway solution compared to gravel driveways, regular concrete driveways, or asphalt driveways. With benefits like the price, sustainability, and the fact that it can never crack and require a repair, crushed concrete is a great driveway option.

Crushed concrete is used for many different things. We can either crush it with our flintstone rock (this is a 5000lb granite rock) or we process it with a 5000 lb wrecking ball. Once it's reduced to smaller pieces, we process it through a smaller crushing plant and depending on how many screens are used we can get it to a 2 to 3 inch minus ...

Recycled crushed concrete begins by breaking down original structures. This can include just about any of the normal concrete structures that would go into landfills, like building slabs, curbs, foundation, and any sort of concrete structure. The breakdown begins by using industrial crushing equipment to demolish the existing structure.

Assume you are using dry gravel with a swell percentage of 15% and a shrink percentage of -7%. Plug those values into the calculator and it will tell you that the compaction factor = 1.237. Multiply the 1185 cubic yards by 1.237. 1185 * 1.237 = 1465.9. To complete this job you will need 1465.9 cubic yards of this gravel in loose state volume.

Calculate Crushed Concrete Road Base. Type in inches and feet of your project and calculate the estimated amount of Recycled Materials in cubic yards, cubic feet and Tons, that your need for your project. The Density of Crushed Concrete Road Base: 2,410 lb/yd³ or 1.21 t/yd³ or 0.8 yd³/t. Type in your numbers.

To calculate yield, you will divide the number of tons of material by the depth to be paved. This will tell you the square yards that amount of material will pave. Take that number—the square yards—and multiply it by 9 to get the square footage and divide that by the paving width to learn the linear feet the material should pave.

Permeability. Studies have demonstrated that recycled concrete has higher permeability than natural aggregates. This means that crushed concrete driveways and other projects are more vulnerable to moisture damage and the elements than new asphalt driveways. Water and humidity are more likely to cause rutting or cracks to the crushed concrete ...

Retaining Walls. Layering crushed concrete is also a great way to create a retaining wall and control erosion on slopes or hills in your yard. Different sizes of crushed concrete can function together to help prevent erosion. A layer of smaller, more broken-up crushed concrete as a base will contribute to the stability of the wall.

Durability is the main concern. Unstabilized, loose crushed concrete has all the downsides that loose gravel does. It spreads and thins easily, requiring you to add more and to constantly even out your driveway so it doesn't develop bare spots and ruts. Crushed concrete also creates dust rather easily, which can stick to your vehicles and ...

clay and granulated fluff. As ωincreases, compressive strength decreases. On the contrary, both the workability (i.e., the spread measured through the cone slump test) and the post-peak fracture toughness in compression increase with ω. Depending on the required structural performances and on the concrete workability, the optimal value

The formula for calculating the volume of crushed stone. Crushed stone 5-10, 5-20 mm: 0.74 cubic meters in one ton. 20-40 millimeters: 0.76 m3. 25-60, 40-70 mm: 0.72 m3. Before making a decision about buying or using crushed stone in construction, you should double-check the variety by checking all the details with your supplier.

The same excavation in feet: Excavated area is 200 feet long 20 feet wide and 2 feet deep with a listed swell of 40% for the material. Bank volume = 200 * 20 * 2 = 8000 ft³. Convert 8000 ft³ to yd³ = 8000/27 = 296 yd³. Loose volume = 296 * 1.4 = 414 yd³. (Calculations are based on the material being of similar consistency.
