Frequently Asked Questions
How do I know if my asphalt driveway or parking lot needs to be replaced instead of repaired?
The answer depends on the overall condition of the pavement. Minor cracks, small potholes, and surface wear can often be repaired, while widespread cracking, poor drainage, or a failing foundation may require replacement. A professional inspection can determine the most cost-effective solution for extending the life of your asphalt.
How often should asphalt be sealcoated?
Most asphalt surfaces should be sealcoated every 2–4 years, depending on traffic, weather exposure, and the condition of the pavement. Regular sealcoating protects against UV rays, water penetration, oil spills, and oxidation, helping your asphalt last longer while maintaining a clean, black finish.
What is the difference between sealcoating and asphalt paving?
Sealcoating is a protective maintenance treatment that helps preserve existing asphalt. Asphalt paving involves installing new pavement or replacing damaged asphalt. While sealcoating improves appearance and extends pavement life, it cannot repair major structural damage or large potholes.
How long should I stay off newly paved or sealcoated asphalt?
The exact time depends on weather conditions and the type of project completed. In most cases, foot traffic is allowed before vehicle traffic, and warmer temperatures may require additional curing time. Your contractor will provide specific recommendations before the project is complete.
Why do potholes form?
Potholes develop when water enters cracks in the pavement, freezes and expands during colder weather, then weakens the base beneath the asphalt. Traffic eventually causes the damaged area to break apart. Repairing cracks early is one of the best ways to prevent costly potholes.
Why is parking lot striping important?
Fresh striping improves safety, traffic flow, and the overall appearance of your property. Clearly marked parking spaces, directional arrows, fire lanes, and ADA-compliant spaces help customers navigate your parking lot while keeping your business compliant with local requirements.
How long does an asphalt driveway or parking lot last?
A properly installed asphalt surface can last 20 years or more with routine maintenance. Sealcoating, crack filling, prompt pothole repairs, and good drainage all help maximize the lifespan of your investment.
What factors affect the cost of an asphalt paving project?
Several factors influence pricing, including the size of the project, existing pavement condition, excavation requirements, drainage, asphalt thickness, and any additional services such as striping or concrete work. Every property is different, which is why an on-site estimate provides the most accurate pricing.
Can asphalt paving be completed year-round?
Asphalt performs best when installed during warmer months because temperatures affect proper compaction and curing. Weather conditions play an important role in scheduling, and your contractor will recommend the ideal time to complete your project for long-lasting results.
