If you already asked her and she said no politely via friend zoning. I think thats your answer. You can either just try and get over her and stay friends, or tell her you want to date her and not be trapped as friends.
Really though, I think she gave you your answer, so get her drunk and see what happens, otherwise just go find some other girl you don't really care about and try dating her for a little bit casually. See if she gets jealous and says something.
Personally, most of my friends are girls, and my rule is to keep them as friends unless I am interested and they make the first move. This is the 21st century, girls can make the first move, so you might as well wait it out and see what she does.
