Fill A Crack In An Asphalt-Filled Trench's Surface And Apply Sealer

Posted on

If a new utility line was installed on your company's property and the asphalt-filled trench that covers it has a small crack in its surface once the project was completed, fill in the damaged section with cold patch and apply sealer to the asphalt surface to provide it with a uniform appearance by completing the steps below.


  • asphalt cleaning agent
  • long-handled scrub brush
  • water hose
  • container of cold asphalt patch
  • bucket
  • mixing stick
  • trowel
  • putty knife
  • vinyl tarps
  • container of asphalt sealer
  • thick-napped paint roller
  • extension handle
  • roller frame
  • paint tray
  • rubber-tipped squeegee
  • signs

Clean The Asphalt Surface And Fill The Crack

Apply a small amount of an asphalt cleaning agent to a scrub brush's bristles. Work the cleaning agent into the asphalt's surface by moving the cleaning tool firmly over dirty sections. Once finished, rinse the asphalt off with a strong stream of water and wait for the treated surface to dry.

Pour some cold asphalt patch into a bucket. Mix the patch with a stick until the product is an even consistency. Use a trowel to apply an even layer of the patch to the crack. Use one side of a putty knife to smooth out the surface of the patch. Wait for the patch to harden.

Apply Sealer To The Asphalt-Filled Trench's Surface And Spread It Out

Cover the property that is adjacent to the asphalt-filled trench with vinyl tarps so that the sealer doesn't accidentally stain any portions of the ground. Pour some of the contents of a bucket of asphalt sealer into a paint tray. Stand next to one corner of the asphalt-filled trench. Use a thick-napped paint roller that is attached to an extension handle to apply the sealer in straight lines.

Use a rubber-tipped squeegee to spread the sealer out if too much of it has been applied to some sections. Apply more sealer to the rest of the asphalt with a paint roller and spread it out with a squeegee until the surface of the asphalt-filled trench is covered with an even amount of the product.

The sealer will require several hours to dry. Post a sign on each side of the trench so that your employees or customers do not walk on the wet sealer. Once the sealer has dried, remove the signs. The asphalt-filled trench will be restored to the state it was in before the new utility line was installed.
