There are overlapping classes of surfaced and unsurfaced roads, and undoubtedly the nomenclature used to identify them varies from place to place. At the simplest level, you have a "track" created and maintained by habitual use. In U.S. usage, the term "two-track dirt road" or "two-track forest road" may be used for roads of this type. You can see examples of this type of road here.
A step beyond a two-track dirt road is a "graded dirt road" (as shown in the pictures here), which has been cleared and leveled by a grader (an earth-leveling machine). This, I think, is the type of road that the poster is asking about.
Another step involves pouring and distributing a layer of gravel over the graded dirt road; this would be a "gravel road." As the images here indicate, there is some looseness in distinguishing between a gravel road and a graded dirt road and, but according to the Wikipedia article for Dirt road, the two have different features:
Compared to a gravel road, a dirt road is not usually graded regularly to produce an enhanced camber to encourage rainwater to drain off the road, and drainage ditches at the sides may be absent. They are unlikely to have embankments through low-lying areas.
Beyond that are roads with smoother aggregate surfaces, such as macadam roads. And finally there are paved or sealed roads of asphalt, concrete, Tarmac, or other combinations of materials.
