How do I make a loop-de-loop without distorting the track?

I'm relatively new to Blender and I'm trying to make a race track. There is supposed to be a loop-de-loop and I'm using the array-curve modifier technique to do that. However, when I try this, the track tilts at the end of the loop, and that's a result that I don't want. Is there a way to make a loop-de-loop that doesn't cause the track to distort? Thank you for reading
