Well, it depends on how much thin-set you have to remove. Either A: hammer and chizle or B: rent a machine that uses a mechanicle chizle from a tool rental place. It will get it up for you, BUT..... Make sure you wear protective clothing and eye protection. This advise isn't just to "be safe" because the flying chips can really really hurt. They can break the skin, so ... .be careful...
Concrete generally has larger aggregate than mortar.
If you are positive that it is asphalt I would not suggest adhering tile directly to the asphalt. If removal of asphalt is not an option I would install a subfloor and use thinset mortar to adhere the tile. Another option (probably the better option) would be to pour a concrete mix over the asphalt. Than use thinset to install the tile. The concrete will incapsolate the asphalt. Asphalt more than likely has oils in it and can be a hazard.
