Asphalt Paving Services
Asphalt pavement is utilized in a wide range of applications. It is favored for its durability, strength, ease of construction and relatively low cost. Asphalt is one of the most preferred materials for parking lots throughout the United States as it can handle considerable weights. When properly maintained, asphalt surfaces can last for years.
It is imperative that each property owner adopts a pavement management plan in order to boost the lifespan of his asphalt parking lot. Such a plan should include continuous preventative maintenance efforts along with regular inspections of the surface’s integrity. Let’s take a look at some of the most popular asphalt maintenance procedures used for parking lots around the globe.
Asphalt Repairs and Patches
The most common asphalt repair is patching spaces of the pavement containing potholes. Such imperfections occur as water moves down into the pavement through poorly sealed or totally unsealed racks. In terms of the actual repair procedure, the impacted areas are filled with either a hot or cool asphalt mixture. The type of mixture used depends on the specific site location or the time of the year when the repair is performed.
Removing and Replacing Asphalt
While asphalt pavement moves through its lifespan, its aesthetics deteriorate. If very small cracks exist, they can eventually spread across and down into the asphalt. If regular maintenance is not performed, it is possible for water to seep through these hairline cracks. The result is the formation of holes that negatively impact the substrate. If such a situation arises, the best repair process is the removal and replacement of the impacted area.
In situations where asphalt failure occurs, the most economical solution to improve the surface across posterity is the resurfacing of the asphalt pavement (commonly called the “overlay”). Property owners who find grade depressions (idle water along the pavement) and/or considerable spaces of interconnected cracks that generate blocks like an alligator’s skin, should have the pavement resurfaced. Resurfacing asphalt requires a series of steps: prepping the area, cleaning, doing the actual resurfacing work, leveling off asphalt in lower spaces, grinding transitions and altering drainage structures in the appropriate manner.
Leveling Binder: In low lying spaces, hot asphalt is applied at a series of depths to alter the pitch to the appropriate grades while simultaneously enhancing the parking lot’s fortitude.
Butt Joint or Grinding: Spaces that require a resurfacing that ties into other surfaces like concrete can benefit from butt joint / grinding. The asphalt is taken away around the far edges to permit the ideal amount of depth.
Geotextile Reinforced Resurfacing: When asphalt is resurfaced, Petromat is an option. Petromat is a petroleum-based, non-woven geotextile that is applied in an effort to slow the reflective cracking in the spaces between the freshly installed asphalt surface and the existing pavement. Petromat functions as a waterproofing barrier while improving strength and structural integrity.
Transitional Milling: Spaces that require a connection between the resurfacing and existing surfaces will benefit from a milling of the asphalt. Once milled, it is replaced to permit exactly the right amount of transitions and depth. This occurs with an asphalt milling machine that takes away just the right amount of pavement depth through a grinding process. Any resulting spoils are removed from the site and recycled.
