Frequently Asked Questions

How long should I stay off my new driveway?
48 hours is the standard time, however, if rain occurs or low night temperatures (say below 50 degrees) it could be as little as 24 hours.

What is the maintenance on my new driveway?
Personally, I recommend sealing your driveway the following year after paving. Then, it should be sealed every other year thereafter. If it still looks good, you can wait two years between coatings. If your driveway is steep, you may want to avoid seal coating altogether, as seal coating will cause your driveway to have a slicker surface. Call our associate Mt. Top Seal Coating for more details at 301-334-2831.

Why do I have bumps or bubbles coming up on my driveway? 1 2
If this occurs more than likely it's a dandelion trying to grow through your asphalt. We always take precautions to kill any grass or weeds before paving, but on occasion a dandelion might be overlooked. Believe it or not, they can grow through asphalt. If this happens apply a killer on the plants and tamp the bubble back down with a tamper (a flat board and hammer will work). You should never see it again.

Why did my driveway crack? 1
Some cracks can’t be explained, but they are usually due to a sub-base problem. Blacktop doesn’t have any bridging capabilities, therefore, if more weight is applied to it than the sub-base can withstand, the blacktop will move along with the sub-base and eventually crack. If the sub-base doesn’t move, the blacktop should not crack. Asphalt is weakest at the seams where 2 seperate pads come together. It is not unusual for cracks to form in these areas as the asphalt enters its later life cycle.

How long will my driveway last?
Driveways are like cars in that due to the multiple factors affecting their longevity, it is hard to predict how long one will last. For the most part, however, you can expect 13-18 years life expectancy on a new driveway. Sealcoating every few years will help extend the life of your driveway.
What are these scuff marks on my driveway?  1
Power steering scuff marks are the number one problem in the Northeast United States. The asphalt binder (black tar) used to make the asphalt is only so flexible as far as temperature change, i.e, high temperature to low temperature. Because of the extreme cold and possibility of low, frigid temperatures in the winter, we must use an asphalt binder that can withstand below zero temperatures without cracking and becoming brittle. Therefore, it can only expand to withstand a high end temperature of about 140 degrees before it starts to become soft or pliable. When the sun heats up your pavement on an 80 plus degree day, the surface temperature of your driveway can reach 140 degrees plus, making it more susceptible to scuff marks.

How can I prevent scuff marks from occurring?
Never sit still and turn your power steering. Try to remember to turn your steering while your car is moving and that should prevent a scuff from occurring.

What should I do if I get a power steering scuff?
Really, I have never seen a power steering scuff ever damage a driveway to early failure. The scuff marks are unsightly and look worse than they actually are. However, if you do experience a bad one, you can take an 8” x 8” flat hand tamper and tamp the scuffed area. This method should be utilized on a hot day when the ashault is most pliable.

If I seal my driveway, will that help prevent power steering scuff marks?
Unfortunately, no. Seal coating will cover the mark, but the rough spot created by the scuff will still remain and be visable, but usually to a lesser degree.
