 I am surprised that the article left out the important component of a Chaussee, the lime.  See the first sentence in the French Wikipedia under ""Chaussée"". The French for lime is ""chaux"", clearly the origin of the word Chausee, and this component is critical because the calcium ions in lime (calcium hydroxide) form links with the silicate ions and silica in rocks/stones.  The compaction of soil and/or gravel with calcium compounds like lime is called stabilization, which makes the resulting mass less subject to erosion or mechanical deterioration during use.  I need to learn how to add a reference to a Wiki article, so I can cite my French Wiki source. https://fr.wikipedia.org/wiki/Chauss%C3%A9e
