Cracks are the first sign your asphalt is losing its protective surface. Ignore them long enough and water works its way down, weakening the base and turning small issues into potholes and costly repairs. The good news is many cracks can be handled early with professional asphalt crack filling, which is one of the core services offered by Oscar’s Asphalt and Sealcoating.
Why asphalt cracks form in the first place
Most cracks come from a mix of everyday stress and weather exposure. Traffic loads flex the pavement, sunlight dries out the binder, and water sneaks into weak points. Over time, that combination creates openings that spread and deepen.
Once water enters a crack, freeze thaw cycles and heavy vehicles speed up deterioration. That’s why fast crack filling is one of the easiest ways to protect the surface and extend pavement life.
Cracks that usually need crack filling
Crack filling is typically the right call when the pavement is still structurally sound and you’re dealing with early stage surface separation. Examples include:
- Narrow cracks that have not turned into broken, crumbling edges
- Short, isolated cracks that are not spreading into connected patterns
- Cracks that are dry enough to be properly cleaned and sealed
This approach helps block water intrusion and slows further cracking, especially when paired with sealcoating.
When a crack needs repair instead of filling
Some cracks signal a deeper problem than the surface. Repair is often the smarter move when you see:
- Wide cracks with crumbling edges or missing asphalt
- Alligator cracking, a connected web pattern caused by base failure
- Cracks that dip, puddle water, or feel soft underfoot
- Areas where cracking is paired with potholes or repeated patch failures
In these cases, filling alone is a temporary bandage. A targeted asphalt repair or pothole repair is usually needed to restore stability and prevent repeat damage.
The best time to schedule crack filling
The best time is before cracks expand and before water has months to work underneath the surface. If you manage a commercial lot, consider bundling crack filling with striping updates so your property looks clean, organized, and safe. Get a free estimate today.
