If you are doing per-destination sharing then the behaviour will be the same (for that traffic) as if you didn't have the 2nd 512k link. The traffic will queue until it exceeds buffers and then be dropped.

Depending on what sort of traffic it is, a higher level protocol may notice the dropped packets and implement some sort of flow control to slow the session down (but that has nothing to do with the router).
