The owner of a pea gravel path has to get used to raking and refilling gravel from time to time.

It can shift under pressure, creating footprints or trails behind your car. However, pea gravel also has its downsides. It will be not only pleasant for the feet of your children (because of its smoothness) but also attractive to the eyes of you and your neighbors. We can go for pea gravel that consists of smooth, round, naturally-weathered stones. Shape – we will talk about shape in terms of the topmost layer of our gravel path. At higher levels, we would like to have gravel of a smaller size that will fit into the holes between the stones of the foundation layer. We can add sand or dirt to this basal layer of gravel. First, we can lay machine-crushed gravel of a larger size that will serve as a solid foundation for more aesthetic higher layers. 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.

Step one is establishing the volume of gravel needed.
