It is impossible to give a good answer without seeing the site in person. You must take not of where the water is coming from, where it is going, and how it gets there. When roads are built the right way, on ridges, it is very easy to properly work with the water that lands on them.
How the roads are built? Are there chemicals or salts used on the road in winter? Where is the water coming from? Where is it going? Where does it naturally stay? These are the questions to ask. Watch the water and how it moves and you will have your answer.
