Why Is Your Driveway Cracking?

Do you remember what your asphalt driveway looked like when it was freshly paved? The perfectly smooth surface and deep black color made your home stand out, but chances are it doesn't look like that anymore.

If you don't properly maintain your asphalt driveway over the years, that jet black finish will fade to a dull gray, and the formerly smooth surface will start to resemble alligator skin. If this is what is happening to you, here are some potential reasons as to why your asphalt driveway is cracking.

Poorly Installed Base

The quality of your driveway is only as good as the paving company who installs it, which is why it is important to deal with an experienced contractor. Improper installation is the leading cause of driveway cracks, usually because the base was installed using sand or dirt instead of crushed stone.

Cold Weather

The freeze-thaw cycles of colder climates really take their toll on asphalt driveways. This happens when the water from melting snow or ice penetrates the surface of your driveway, making its way to the base. When the temperature drops, this water freezes and expands, causing cracks to form deep down. As more water enters, freezes, and expands, these cracks continue to grow until they eventually come to the surface.

Tree Roots

When paving your driveway, you should pay close attention to surrounding trees – especially large ones. Much like the freeze-thaw cycle, tree roots can put a substantial amount of pressure on your asphalt driveway from underneath. You can install a root barrier system along the edges of your driveway during installation, but be aware that these can compromise the stability of the trees.

Excessive Weight

Asphalt is a very strong material, but it is not invincible. Just like pressure from below can cause cracking, so can pressure from above. Don't park commercial vehicles on your driveway, and try not to park close to the edge, where the foundation is its weakest.
