Gravel, along with other types of rock fragments such as sand and. Gravel is a loose mixture of rock fragments formed as a result of erosion. It also estimates the cost of purchasing a given amount of gravel. Pricing for the service is unfortunate unpublished, but you can fill out this form to inquire about pricing for your job site. The formula for the volume of a cone is RH/3, where R is the radius of the circular base and H is the height of the cone. The following calculator helps estimate the amount of gravel needed to cover an area based on the density and desired depth of the gravel. More importantly you gain valuable historical data with a few clicks of a button. The volume of a cone is (pi/3)R²h but we know h is limited to about 0.7R. This gives a height of 0.7R where R is the radius of the pile. Droneįor those contractors that are partaking in the drone craze, you can even use your own drone to take aerial images of your stockpiles, upload them to the program, and get your results.Īccording to the company website, the accuracy of the data is between 2-4%. Since there is a risk of collapse, I would use the smaller number. The only other thing the users need to do is tag the stockpile and view the results. Aerial PhotosĬustomers of Stockpile Reports can request an aerial flight directly through the company and will receive their stockpile data within hours of the flight. This represents the total percentage passing from all aggregates. The iPhone app can be downloaded by clicking here. The formula to calculate the percentage passing each sieve is as follows: (CA/100 x passing CA) + (FA/100 x passing FA ) For No. To use enter the required data in the highlighted cells Conical Stockpile Capacity 1. The actual tonnage is calculated based on the bulk density of the material. ![]() Simply position the cones 25 feet (10m) apart and in front of the stockpile, select the stockpile material in the Stockpiles app, and walk around the pile while taking a video. Measurements will be made of the stockpile of gravel or coarse aggregate to calculate the volume of the stockpile. This form is for calculating the volume contained in a conical stockpile. ![]() The great thing about this app is that it doesn’t require any special equipment or training, just an iPhone, 2 orange traffic cones and a tape measure. Use SR Measure to measure stockpiles at construction job sites, aggregates.
