Rent a trash bin. You will be throwing all scrap blacktop that is torn up into the bin. The trash bin company will dispose of the blacktop properly once it is full.
Cut 12-by-12-inch squares into the blacktop using a hammer drill with a chisel bit. This will weaken the blacktop.
Break up the squares with a jackhammer. Continue to jackhammer the blacktop until is is reduced to rubble.
Shovel the larger pieces of rubble into a wheelbarrow and dispose of it into the trash bin.
Gather the smaller blacktop debris with a metal rake and move it into the trash bin.
