How to Repair Large Cracks in Asphalt Driveway

Large cracks in asphalt driveways can cause major structural problems if not fixed on time. Water can flow through these cracks or fissures and weaken the foundation, worsening the situation.

Fixing these big cracks is not only doable but will also prolong the life of your asphalt driveway if you use the correct technique. For help with this typical issue, here is a detailed guide.

Identify the Type of Cracks

To avoid and fix cracks, it is necessary to understand their causes:

As a result of weathering, asphalt loses its flexibility and eventually cracks when left in the sun for too long.
When water seeps into cracks and crevices, it can freeze and expand when the weather gets cold.
The constant impact from large vehicles can wear down asphalt roads.
Premature cracking can be caused by improper installation, which includes insufficient compaction or using low-quality materials during the initial installation.

Resources Needed for Success

Here are the equipment and materials you'll need to fix significant cracks successfully:

Pavement crack sealant
Fixing deeper fissures using a backer rod
Asphalt with a cold patch
A bristle paint brush
Broom or leaf blower
Spackling tool
Tool for applying putty or trowel
Protective eyewear and gloves

How Can Big Cracks Fix or Repair?

Fix the Split Thoroughly: Use a wire brush to remove any dirt, weeds, or debris from the crack. Use a broom or leaf blower to remove any loose debris. The optimal adhesion of the filler is dependent on a clean surface.
Evaluate and Get the Crack Ready: Find out how wide and deep the crack is. Utilize a backer rod to cover the space if it exceeds ½ inch depth partially. This not only improves structural support but also aids in filler conservation.
Put the Crack Filler on: Carefully inject the asphalt crack filler using a caulking gun. Ensure there are no gaps or air pockets when filling the crack. To get a flawless finish, smooth the surface using a trowel or putty knife.
Repair the Area Around the Damage: Cold patch asphalt can be used to fix cracks that lead to potholes. Make sure the fix is stable by compacting the patch hard with a tamper or the back of a shovel.
Driveway Upkeep Following Repairs: Seal your driveway every two to three years to keep it in good condition and extend its life. Fix small cracks immediately to stop them from getting more significant. Ensure water doesn't collect on the driveway; asphalt can't withstand standing water, so drainage is critical. Your driveway may last longer, look better, and save money if you repair cracks quickly and keep up with maintenance.
