In this article the classification of natural materials as used in earthworks will be discussed. The general classification is done in terms of a "G" notification, like G5, G6, G7, G8, G9 and G10. Generally a G5 and G6 type of material is classified as natural gravel and the G7 to G10 type of material as a gravel-soil.
