What do sealcoating, striping, and asphalt crack filling actually do? On a sound asphalt surface, they work together as preventive maintenance: crack filling helps keep water out of non-working cracks, sealcoating protects the surface from weather and aging while restoring a rich black finish, and fresh striping improves traffic flow, visibility, and accessible parking layout. That is why FHWA guidance emphasizes using the right treatment at the right time, why the USDA seal-coat guide describes seal coats as preventive maintenance, and why our service page combines crack filling, sealcoating, and line work into one system.
What each service does
| Service | Main job | Best role |
| Asphalt crack filling | Closes non-working cracks to reduce water intrusion | First step before sealing |
| Sealcoating | Adds a protective surface layer and refreshes appearance | Best on structurally sound asphalt |
| Striping | Re-establishes stalls, arrows, fire lanes, and ADA markings | Final step after surface work cures |
That sequence reflects the Kentucky manual, the FHWA crack brief, the ADA brief, and our process.
Why preventive maintenance matters
Asphalt rarely fails all at once. It fades, dries, oxidizes, and opens up to water. FHWA research notes that environmental factors oxidize asphalt binders and make them more brittle, and the USDA seal-coat guide explains that seal coats are meant to protect pavement from sunlight, rain, and snow while limiting water infiltration. In practical terms, that means sealcoating is not just about making pavement look black again; it helps the surface hold up longer and, by slowing weathering, helps it keep its resilience longer.
This is why we view sealcoating and striping as maintenance, not cosmetics. On the residential side, many homeowners simply decide they want the driveway sealed before small issues become bigger ones. On commercial lots, the stakes are even higher because first impressions, traffic flow, and pavement longevity all matter at the same time. But preventive maintenance only works on pavement that is still fundamentally sound; if there is base failure or severe alligator cracking, a surface treatment alone will not fix it, as the USDA guide makes clear.
What quality work looks like
For anyone comparing asphalt sealcoating Dayton options, the biggest question is not only price. It is process. Crack filling should come first, because the FHWA crack brief says crack sealing is performed before most other preservation projects, and the Kentucky manual defines crack filling as placing bituminous material into non-working cracks to reduce water infiltration. Then the surface needs proper cleaning and preparation, especially in stained areas, before sealcoat is applied.
At Moyer, we focus on that full sequence. Our sealcoating service includes chemical preparation for oil-stained areas, mechanically applied sealcoat for even coverage, asphalt crack filling, layout support, and low-VOC paints. We believe the difference between a bargain job and a quality job is usually not the black color on day one; it is the prep, consistency, and finish that hold up after traffic and weather hit the pavement. Lower-cost bids can be tempting, but what you pay for is preparation, material consistency, and workmanship.
Why striping matters
Striping is the finish that makes a lot functional. Clean stalls, arrows, fire lanes, loading zones, and accessible spaces help people understand where to go immediately. It is also where compliance matters. Under the ADA brief, accessible parking counts are calculated for each parking facility, and at least one of every six accessible spaces must be van accessible. That is one reason we treat striping as more than paint; it is part of how a site works.
If your lot or driveway is fading, drying out, or starting to crack, this is usually the stage where preventive maintenance delivers the most value. If you would like a practical recommendation on sealcoating and striping or asphalt crack filling, request a quote.
