This is what I was getting at with checking the turn. This guy is likely thinking about your range and comparing his hand to that. He's aggressive, so like you said, he's not gonna just check/call very much.
The ace on the turn slams your range, and he knows that, so when he makes this raise, I don't think he can ever expect someone who just hit their ace to lay down to this small bet. Therefore he probably has something pretty strong, and wants a call.
When you check that through, it's probably just enough incentive for that aggro guy to try and take it down on the river, and you can easily call his river bet.
