If you need a decent book about road building and maintenance look up 'king road drag' on Wikipedia. Below the article about the drag under the heading "External Links" click the link about the theory and use of the drag (the second listed link). Download that free book 'Highway Engineering, Rural Roads and Pavements'. It provides a lot of information about roads and their construction before the use of heavy equipment. It shows how it was done by horse drawn equipment. I think it is useful for MP settings. A link to a modern book about gravel roads can be found under the external links in the Wikipedia article about gravel roads.
