Frequently Asked Questions

I have noticed parts of my driveway are deteriorating. Should I repair them now or wait a year or two to get the entire driveway resurfaced?

Addressing the damaged areas as soon as they appear is in your best (financial) interest.  Water, sun and normal wear and tear can cause further damage to these areas.  It is cheaper to repair the deteriorated areas before they start to spread and you have no other choice but to resurface or repave.

Is Sealcoating Asphalt Pavement Necessary?

Sealcoating protects and extends the life of your asphalt investment.  Applying a high quality sealant prevents water from seeping into cracks, which can cause bigger problems. Sealcoating is a cost-effective way to minimize the need for repairs, make your pavement appear new and provide curb appeal to your property

What is the difference between resurfacing and sealcoating?
Resurfacing is considered a structural repair, while sealcoating can be likened to applying a coat of paint to your house. With asphalt resurfacing, you are essentially putting asphalt pavement on top of the older asphalt surface.  Resurfacing only works if less than 25% of the surface is cracked or needs repaired, the foundation is structurally sound and the cracks are shallow and smaller than a quarter-inch wide.  Sealcoating is preventative, which means it protects and extends the life of your asphalt, but does not structurally repair it.
When Should I Sealcoat my Driveway?
Asphalt pavers recommend that you apply a high-quality sealant every three years.  For newly paved driveways, you should wait at least 90 days before applying a sealcoat, but If possible, it is highly recommended that you wait nine months to one year.  Sealing your driveway before it’s completely cured can seal in the oils that make the asphalt flexible, which makes your driveway susceptible to tire marks and imprints from pointed or heavy objects.  For optimal adhesion, it is recommended that the outside temperature be more than 50 degrees, but less than 90 degrees when sealcoating.
While you can do your own sealcoating, hiring professionals that specialize in asphalt paving and sealcoating services, like RoadStar Paving in Pittsburgh, is highly recommended.
 
Why do I have grass growing in my new driveway?
Asphalt, properly compacted, has about 10% air voids.  A seed of grass can get into the mix and germinate causing the grass to appear.  Your best bet is to spray a mild weed killer on it.
Why do I have puddles in my driveway?
Puddle formation can be caused by a variety of factors, but most common are indentations by vehicles or heavy equipment, poor compaction during installation, improperly installed sub-base or inadequate drainage.   Pooling water accelerates the breakdown of asphalt. If water seeps into cracks and reaches the base layer, it can have damaging effects, especially during colder weather as expansion and contraction is brought on by freezing and thawing.  If puddles are a regular occurrence, it is important that you identify the cause and resolve it immediately.
Will patching my driveway look OK?
It depends.  When patched, you will have a black area of asphalt in the middle of your grayish pavement.  If you have previously sealcoated your driveway, the new asphalt will have a more porous texture. Depending on the size of the repair, some people may not mind and others may see it as an eyesore.  If you are one of the latter, you may want to consider having the whole driveway resurfaced or sealcoated after the patching is completed.
