Typically road base comprises a mixture of blue or grey rock fragments around 20 mm in size with smaller rock particles and dust (fines). Crusher dust is produced when recycled concrete or rocks are crushed. It is finer than road base comprising particles that are 5 mm or smaller in size mixed with fine particles, such as soft sand.
