Volume loss with crushing gravel
the volume of gravel material that is blown away or lost from the surface can be estimated at 1 ton of material per mile/vehicle/year. To put it another way, consider a sample roadway with a traffic volume of 250 vehicles per day, we can estimate a loss of 250 tons of gravel per mile/year. That is 10 semi loads of gravel on a mile section of

After initial crushing and screening, industrial sand and gravel are washed to remove unwanted dust and debris and are then screened and classified again. The sand (now containing 25 to 30 percent moisture) or gravel then goes to an attrition scrubbing system that removes surface stains from the material by rubbing in an agitated, high-density

Step one is establishing the volume of gravel needed. It is equal to the volume of an excavation, and you can do it in the following way: Determine the length and width of a cuboidal excavation. In our example the excavation length is l = 6 yd and the width is b = 3 yd.; Calculate the area of the excavation, multiplying the length and width together. In our case, A = 6 * 3 = 18 yd².

inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement. They total 90 to 95 percent of the mixture by weight and 75 to 85 percent by volume.

Aggregate. Aggregate is the most exploited material in the world. It is an important component of concrete and asphalt concrete, accounting for 70% of the volume of concrete. It can inhibit the shrinkage and cracking of concrete and enhance the strength of concrete. Aggregates are divided into natural aggregates and artificial aggregates.

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.
