I'd be pissed if it cracks anytime soon. 4 " of base and 3" of asphalt compacted .It was expensive 4200 sq.ft.. Old asphalt was suppose to be 2" not 1.5 to 1.75".OUCH !! that cost ya! Probably won't crack before this Winter, but when it does, be sure to seal up cracks before water-ice gets in them ...the death of asphalt...........................MO
