Step 3. Clean loose earth and debris from the hole with a garden shovel, trowel, or other suitable tool

If the bottom of the hole is dry soil, it is advisable to use a systole to moisten it because the tar does not stick to the dry soil.

If you are in a hurry you can also use a fan or hairdryer.

Step 5. Fill holes that are more than 8-10 cm deep with material that can be firmly compacted, such as clay, crushed concrete, or crumbled limestone

For repairs where the material under the patch cannot be compacted with normal methods, to stabilize the area it is advisable to dig the hole even deeper and pour concrete up to about 5 centimeters below the decking.

Step 6. Fill the hole with asphalt filler to about an inch above the adjacent road pavement

This will allow the patch to be at the same level as the existing pavement after compaction.

Step 7. Compact the fill with a hand compactor, motorized plate compactor, or, for very small holes, even a mallet

Make sure the cold asphalt mix is firmly pressed or you will find that the patch will give way quickly when exposed to traffic.

Step 8. Cover the patch if possible

While it is optional, you can place a board or piece of plywood over the repair for a few days to harden it more. If you have pressed the filling hard, it can be walked over immediately.

Advice

  • For repairs larger than 20 square decimetres, a plate compactor is very useful.
  • You can wash the tar off your hands with a good mechanics hand-washing soap; be careful to use solvents such as white spirit, lubricants, or other chemicals as they can damage your skin.
  • If you want, you can pry the pavement adjacent to the patch so that the new filling material can support the edges weakened by the cause that caused the original hole.
