Regardless of the machinery employed, the aim of grading is always to restore or maintain what the FHWA calls “road geometry,” or the necessary cross-section for a functioning unpaved road. The operating speed of machinery must be kept low (3-5 miles per hour or less) in order to ensure a good shaping job — anything faster than that will compromise the quality of the grading.

Coarse-grained soils can be further dived into two sub divisions, gravel or sand. If 50% of the sample is larger than 4.75 mm, the soil is classified as gravel. If 50% of the sample ranges between 4.75 mm and 0.075 mm, it is classified as sand. Fine-grained soils have 50% or more smaller than 0.075 mm.

Soils with large percentages of sand are easier to work than soils with large percentages of clay. Clay soils tend to be tighter, making them more difficult to break up or cultivate, whereas sandy soils are looser. A clay soil also takes longer than a sandy soil to dry after a rain. Because of the better drainage, a sandy soil can be worked sooner.
