Few building materials are as well suited for driveways as asphalt. Not only is asphalt aesthetically attractive but, when installed correctly, it will last for years to come. If you would like to learn more about best practices for asphalt installation, read on. This article will introduce three valuable tips for getting the most from your new driveway.
1. Begin with a gravel base.
In the end, your asphalt driveway is only going to be as strong as what you put beneath it. Asphalt installed directly atop a packed dirt surface is vulnerable to water damage, and won't last nearly as long. As the soil below gradually erodes, your beautiful new asphalt will lose critical support, leaving you with a driveway full of cracks and potholes.
You can avoid this scenario by installing a base layer of gravel beneath your asphalt. Once compacted, this gravel provides a firm, durable foundation. Not only that but it also allows excess water to drain down to the soil, thus keeping your asphalt nice and dry. Just make sure that your layer of crushed gravel is deep enough to be effective--six inches is a safe bet.
2. Build your base wide, not just deep.
You've probably seen it before--asphalt driveways with jagged, crumbling edges. This is the result of an insufficiently wide gravel base. In order to keep this from happening to your new driveway, it is vital that your base be wider than the driveway by a minimum of one foot. This will provide lateral stability, and keep your driveway from crumbling away each time somebody accidentally drives over the edge.
3. Add a layer of geotextile.
Gravel alone will provide a reasonable amount of structural stability for your driveway. But if you're determined to go the extra mile, consider installing a layer of geotextile as well. Known also as filter fabric, geotextile comes in large rolls. Sheets are cut to the proper size and installed beneath the gravel.
Geotextile acts to provide a vital layer of protection, keeping particles of soil from migrating upward into the gravel. Over time, such migration can lead to significant amounts of soil--and moisture--coming into contact with the bottom of your asphalt. By negating this issue, geotextile greatly enhances the stability of your asphalt. In fact, it has been suggested that even a single layer of filter fabric provides as great a stability increase as an additional 1-1.5" of asphalt.

Having a driveway and parking lot paves on your property is an excellent way to ensure that you don't have to deal with mud, rocks, and tons of insects every time you leave the house or head back home. However, pavement needs to be properly taken care and maintained if you expect it to hold up to wear and tear throughout the years. Getting rid of the weeds is one of the biggest aspects to focus on. Weeds can grow right through the pavement and break it apart until cracks and chips occur if left unchecked. This blog was designed to help you maintain the integrity of your newly paved driveway so it stays beautiful for decades to come.
