Advice on this hand.

This guy had been raising a lot on third street, so I didn't think it was very likely he had a pair of aces, but I decided to just call with the intention of raising on a later street so I could represent a hand stronger than a pair and also give myself the chance to hit a Queen cheaply. When another ace appeared on the other guy's board, I decided he probably didn't and wanted to isolate him by forcing the player with the probable flush draw to call a double bet. Is there another way I should've played this? Perhaps reraise on 3rd street? Should I fold to his reraise on 4th?
