5 Things To Know When Installing An Asphalt Driveway
Posted on: 20 May 2021
A new asphalt driveway is a major investment. You want to make sure it is built to last and that it meets your needs.
1. Base Depth
All asphalt driveways begin with a sturdy base. The base, in many ways, determines how well your new driveway will stand up to the test of time. In areas with little ground frost and light use, the base may consist of as little as a few inches of gravel. If your driveway has heavy vehicles parking on it or if freezing is common, then the base should be deeper to ensure that it can better support weight and to ensure it is below the frost line so heaving doesn't occur.
2. Drainage Integration
Drainage can be an issue for some driveways. Water may collect on the surface and lead to potholes if there is a low area, such as where the driveway meets the sidewalk. There can also be washouts beneath the driveway from draining water along the edges. Integrated drains can be installed at the time the asphalt is put in, which can help prevent future erosion and drainage issues.
3. Asphalt Type
There are different types of asphalt mixes, with the differences often being determined by the aggregate type mixed in with them. You can get asphalt with a rougher surface for better traction or one that is almost perfectly smooth. There are also permeable asphalts that allow more drainage through the paving so that there is less water loss via evaporation.
4. Finishing Options
You may have the option of adding some finishing touches to the driveway. This can include the installation of decorative curbing along the edges if you don't want the standard asphalt edge to show, for example. Some people also opt to have reflectors embedded in the driveway, perhaps to make it easier to see the entrance at night. You can also have a decorative aggregate surface installed over the top of the asphalt layer if you prefer a different look for your driveway.
5. Sealcoating
The final step for a long-lasting driveway is sealcoating, but this isn't typically done right after installation. It's best to wait for the asphalt to fully cure. A sealcoat is an additional waterproof coating that will help protect the asphalt against weathering and increase its longevity. Your installer should inform you of the best time to schedule this follow-up service.
