Asphalt Pavement: Insight To Help You Install Durable Edges And Protect The Surface For Long-Lasting Use

Posted on: 29 December 2017

An asphalt paved surface that has been well-built retains a flexibility that gives under the weight of traffic without cracking and crumbling. When you are preparing to install an asphalt driveway in your yard, it is pertinent to install the pavement properly to ensure it remains stable. Here are some tips to help you install the pavement edges and protect its surface structure for the life of the pavement.

Supported Edges

Part of installing supported edges on your asphalt is installing the base material. The layer of gravel foundation should be several inches thick to provide a stable drainage for your asphalt and support the free edges of the asphalt driveway. When laying your compacted gravel foundation, make sure to extend the gravel layer several inches past where the edge of your driveway will sit. If you plan to frame your asphalt driveway with concrete or other solid structure, you don't need to extend the gravel foundation in this manner.

It is also important when compacting your asphalt surface, to angle the edges of your asphalt at a 45 degree angle. Providing this angled edging on your asphalt provides support to help the asphalt resist crumbling and other damage from excess weight and pressure from vehicles and foot traffic. The aggregate and emulsion-bound edges of your asphalt can crumble when the flexible material does not have sufficient support.

Protected Surface

Once your asphalt has been installed with the proper base foundation, keeping its surface protected is also critical in helping to maintain its structure. This includes repairing cracks and holes and protecting it with the proper sealant.

As asphalt ages, it begins to dry out and surface cracks appear that can grow larger if left unrepaired. The longer surface oxidation and cracking are left to damage your asphalt, the more severe the damage will become and may require resurfacing of your driveway.

Clean out the cracks of any dirt, debris, rocks, and vegetation to ensure your repair adheres in the crack. Use a broom or pressure washer to clean out debris and a sharp tool to cut out vegetation growth. Apply a crack filler asphalt compound into the crack, compressing it to remove any air pockets and to ensure its adhesion into the crack. Thinner, hair-line cracks, you can fill with a liquid asphalt crack filler.

Be sure to follow up all crack repairs with a sealcoating application to seal in the surface of the asphalt and its cracks, and restore the moisture and flexibility to the surface. Contact a company, like Lakeridge Paving Company, for more help.
