Utilized in a variety of applications, asphalt is a cost-effective surface for roads, parking lots, and driveways. Reece provides quality asphalt paving at great prices.
There are several factors that influence the lifespan and quality of new asphalt: compaction of the sub-base, depth of pavement, and quality of pavement joints. A quality sub-base should be well compacted, and comprised of appropriate materials for the specific application. For commercial applications, we recommend 3-6 inches of asphalt.
For lighter applications, 2 inches of asphalt is generally sufficient. Asphalt is usually paved in multiple passes, leaving joints between each pass. It is important that the joints are properly seamed together, which decreases the likelihood of future cracking.
When asphalt becomes severely damaged or beyond repair with general patching, resurfacing is the most cost-effective way to repair an entire area of pavement. Resurfacing, which is commonly referred to as an overlay can be accomplished in several ways. The simplest procedure is to pave new asphalt directly on top of the damaged asphalt. While, this is the cheapest option, it does have one key drawback: reflective cracking.
Reflective cracking occurs when cracks in the old surface reappear in the new surface over time. Another common method of resurfacing is milling. An asphalt milling machine is used to grind away the appropriate amount of old pavement. The milling process can be used to remove the top couple inches of the pavement, which often contains the majority of damage/cracking. It is also used in areas that transition into concrete pads, curbs, and sidewalks. Once the appropriate amount of old material is removed, it is replaced with new asphalt and compacted. This results in a new surface that is the same height as the original surface.
