If the crack you are trying to patch is deeper than two inches, you may wish to first fill the crack up to the two inch mark with small, crushed, angular gravel. Don’t use pea gravel or other larger gravel as it can shift frequently and does not provide an adequate base.
Next, you should compact the gravel using a steel tamper or a 4x4 wooden post.
Now fill the crack with a cold process asphalt repair compound, such as blacktop.
Compact the compound with a tamper or a 4x4 wooden post.
After compacting, you may need to add more blacktop or compound material and repeat the tamping process to ensure a consistent, level driveway.
