The CBR testing can be applied to soils with a maximum particle size of 20 mm. For soils with bigger particles, other types of bearing capacity can be used like the Plate Bearing Test. Since the coarse-grained soils and fine-grained soils have particles with size smaller than 20 mm, they can be evaluated by the CBR testing.

Gravel Calculator | How much gravel do you need?

Size – there are many sizes of gravel. We can find some with rock fragments 4 inches (about 10 cm) in diameter and others with a particle the size of your fingernail. Of course, different sizes serve different purposes. Normally, we would like our gravel path to consist of 2 or 3 different layers of gravel.

Sand / Media Specifications

Media with small grain size slow the water movement and increase the chance of clogging. The effective size (D 10) and uniformity coefficient (Uc) are the principal characteristics of granular media treatment systems. The ideal sand media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm.
