no issues. A company converted a warehouse in STL to an indoor electric cart track. They put down like 4" of special asphalt inside the building. no issues. (other than they ran over budget, then never finished the attached restaurant and went under a few years later because they didnt have the money from the bar/restaurant).
Stupid question... Is there any reason you would not want to enclose an asphalt pad? I am thinking off gas and that sort of stuff.
