the karts and cars more or less move the pavement around making dips and bumps, but cars have the greater chance of pulling up the asphalt. then you have the rain that gets under the soft asphalt and ruins everything. the asphalt is going to get tore up regardless but more so in the summer than the winter.
from the looks of the pictures they didnt get very good asphalt. thats the same problem we are having with our track.
