Suppose you’re the owner of an asphalt driveway, parking lot, or roadway. In that case, it’s essential to keep up with routine asphalt paving maintenance. Crack sealing and filling are some of the most critical aspects of asphalt maintenance.
If left untreated, small cracks in the asphalt pavement can turn into large potholes, which can be a safety hazard and damage vehicles. The good news is that this type of maintenance is relatively easy and can be done by most homeowners for their residential asphalt pavement.
In this blog post, ABC Asphalt, Inc will discuss how to seal and fill cracks in your pavement.

What is Crack Sealing?
If you notice any cracks with horizontal or vertical movements wider than 0.1 inches, it’s time to take action and seal them. This process is called crack sealing and is an integral part of asphalt maintenance.
Crack sealing prevents water from entering the cracks and causing further damage to the pavement. It also keeps out dirt, debris, and vegetation that could cause the cracks to widen.
We place a hot adhesive sealant into the cracks, which bonds to the asphalt and creates a waterproof barrier. This protects your commercial or residential asphalt paving from further damage and extends its lifespan.
What is Crack Filling?
This repair method is ideal for cracks on the asphalt paving that don’t show significant movement. The only horizontal or vertical movement within these cracks should be less than 0.1 inches.
Using an asphalt emulsion, we fill these cracks, which creates a barrier that protects your asphalt from water and other elements. A less extensive repair than crack sealing, crack filling is a popular solution for residential asphalt pavement.
However, if your asphalt has widespread damage, you’ll want to consider a full-scale repair or replacement.
When Should I Consider Crack Sealing?
As we mentioned, crack sealing is for cracks with movement greater than 0.1 inches. We also call these cracks “working cracks”. A working crack means that the crack is allowing water to enter your pavement. This water can cause extensive damage, so it’s important to seal these cracks as soon as possible.
One example of a working crack is a transverse crack, which runs perpendicular to the pavement’s centerline. These can be caused by thermal expansion, contraction, or even a reflection crack of an underlying layer in the asphalt paving.
When Should I Consider Crack Filling?
As opposed to crack sealing, this procedure is for cracks with movement less than 0.1 inches. These cracks fall under the “non-working crack” category and are relatively easier to fix. Examples of non-working cracks are longitudinal, diagonal, and alligator cracks.
Alligator cracks refer to the cracking pattern that looks like an alligator’s skin. These cracks are caused by fatigue damage and often indicate a structural failure in the asphalt paving.
