Normally, we would like our gravel path to consist of 2 or 3 different layers of gravel. Of course, different sizes serve different purposes. We can find some with rock fragments 4 inches (about 10 cm) in diameter and others with a particle the size of your fingernail. We can differentiate various types of gravel on the basis of the following:

If you are going to use sand instead of gravel, try our paver sand calculator.Ĭrushed stone is another alternative that you can use. Our gravel calculator will display this value for you. The volume of gravel required is equal to the volume of excavation. Multiply the area and depth of the excavation to obtain its volume in cubic yards: 18 × 2 = 36 yd³. We've got calculators to help you find the areas of many geometric figures like triangles or pentagons: visit the 2D geometry section of our math calculators page.ĭetermine the depth of the excavation. You can also type the area of the excavation directly into the gravel estimator if you choose to excavate a more sophisticated shape. In our example the excavation length is l = 6 yd and the width is b = 3 yd.Ĭalculate the area of the excavation, multiplying the length and width together. It is equal to the volume of an excavation, and you can do it in the following way:ĭetermine the length and width of a cuboidal excavation.

Gravel Roads: Maintenance and Design Manual (pdf) (35.91 MB).

The manual is designed for the benefit of elected officials, mangers, and grader operators who are responsible for designing and maintaining gravel roads. The purpose of the manual is to provide clear and helpful information for doing a better job of maintaining gravel roads. This manual was developed with a major emphasis on the maintenance of gravel roads, including some basic design elements.
