Question 1

Should I seal my driveway or replace it?

Accepted Answer

•

If you notice minor cosmetic problems with your driveway, you should seal it. Look out for cracks and holes on the surface, faded asphalt or concrete, and stains from oil and other chemicals. Replacing your driveway may be necessary if you’re dealing with significant problems—¼-inch cracks, large potholes, and puddles from drainage issues. The cost to install an asphalt driveway typically ranges between $4,200 and $9,000, significantly more than resealing. Consider talking to a professional to discuss whether resurfacing your driveway—a midway project between resealing and replacing—is a better option for you.

Question 2

How long or wide does a private road need to be?

Accepted Answer

•

Your city or county will have guidelines about the minimum and maximum width and length of private roads. The average private road is 12 feet wide, and length, of course, depends on your property. Requirements also depend on the amount of traffic and types of vehicles your road experiences. Check with local ordinances before planning a road on your property.

Question 3

What driveway materials last the longest?

Accepted Answer

•

Pavers last longer than both concrete and asphalt when well cared for. Since you can place individual pavers that suffer damage, you won't need to repave the entire driveway for an average of up to 50 years. However, the best material for you comes down to your local climate and budget.

Question 4

What is the lifespan of asphalt pavement?

Accepted Answer

•

You can expect your asphalt pavement to last anywhere from 20 to 30 years, or 25 years on average. The life expectancy of your asphalt driveway depends on the climate, the amount of traffic, and how well you maintain it. While you can’t necessarily control some of these factors, you can control the amount of maintenance effort you put into your driveway.

To prevent your asphalt from deteriorating prematurely, you should follow a good maintenance routine involving regular cleaning, reparation work, and resealing.

Question 5

What is the minimum angle for a driveway?

Accepted Answer

•

Driveways should be sloped with a minimum 2% slope—anything lower will cause precipitation and runoff to collect. A 2% slope is the equivalent of a 2-foot rise over 100 feet. One quick way to check the integrity of your driveway’s slope: no more than four inches of water should collect on the surface longer than 15 minutes after rain.
