Bleeding asphalt is one of the hardest forms of distress to fix. If it is severe enough, it can lead to wet-weather crashes.

You could try rolling some aggregate into it on a hot day (or after heating the pavement), but that may only be a temporary solution. Depending on how bad it is, you may have to 'mill and fill' - grind off the top few inches of asphalt and replace them.

Other options include various forms of asphalt recycling, where you mill the asphalt, mix in fresh emulsion and/or 'asphalt rejuvenator', put it back down, compact it into a new base course, then pave new top-course asphalt.
