Pairing crackfill with asphalt sealcoating allows the lot to have more complete water penetration protection and a consistent black color for top notch curb appeal.
Regular crackfilling in the years after paving will be the best money spent to maintain your investment.
Types of Cracks:
- 1. Transverse Cracks – Cracks that extend in a perpendicular line to the direction of paving or centerline. These cracks are often the first to appear in a parking lot.
- 2. Longitudinal Cracks – Cracks that run parallel to the direction of paving or centerline. Longitudinal cracks show up more over time and are generally caused by poor joint compaction and paving quality.
- 3. Alligator Cracks – Interconnecting cracks resembling a spider web or alligator’s back. These cracks are often caused by heavy traffic use and extended deterioration from water penetration from surrounding open cracks. Often asphalt patching is the best solution to repair these areas.
- 4. Reflective Cracks – Cracking that is caused by a cracked course beneath the surface or shifting base. Reflective cracks can be corrected with full-depth patching, including binder course replacement and even sub-base replacement in some situations.
- 5. Edge Cracks – Edge cracks form from pavement’s expansion and compression due to seasonal weather cycles. They can continue to grow larger if ignored as the freeze and thaw cycles continue to cause these edges to push into the surrounding curb or transition.
- 6. Block Cracks – Block cracks occur toward the end of a parking lot or asphalt surfaces lifetime. They are caused by shifting base material and often appear in blocks throughout the lot. A mill and overlay with base correction would be the best long-term correction for these cracks.
