Despite asphalt’s strength and durability, if lacking routine maintenance, it can fail prematurely. Nature’s elements like UV rays, hold and cold temperature extremes, ice and snow accumulation, and rain, all take their toll on asphalt -; even with protection. These factors weaken the binding properties of asphalt, resulting in cracks and fissures, that can eventually become potholes. Asphalt naturally changes color as it ages from a shiny black to a dull gray and often requires maintenance procedures like sealing and other asphalt paving repair, like filling cracks and patching holes. The following highlights common methods of asphalt maintenance:
* Seal Coating -; This process is not meant to fill cracks or crevices but rather provide a shiny, new surface. It’s akin to painting, you’re rejuvenating a tired surface and discouraging minor wear and moisture penetration, but not repairing damage. Using a motorized squeegee machine is the best method to apply the sealant as it pushes the substance into the asphalt instead of spraying. Spraying coat’s the surface and doesn’t penetrate minute cracks and pores.
* Crack Repair and Filling -; Parts of the country that experience harsh winter weather generally require more asphalt paving repair services. In these areas, the freeze and thaw cycle is particularly tough on asphalt surfaces. It is common for cracks to begin at the edges and seams of the asphalt surface. These cracks make it easy for moisture to enter and if it freezes can cause cracks to expand and widen.
* Patching -; Filling potholes is not an option; therefore, they must be patched. Potholes allow water to penetrate the base resulting in further degradation. Since patching is more expensive, filling cracks is a cost-effective approach over the long-term.
* Overlays -; Despite proper maintenance occasionally asphalt will require an overlay application. Overlays are not the same as sealing and terms are often used interchangeably. Think of an overlay as adding mulch to an existing garden bed, only this is a new, thin layer of asphalt laid over an existing base of asphalt. The condition of the asphalt determines the thickness of the overlay, but in general, it is 1 to 2-inches thick.
Asphalt surfaces constructed by companies like website are substantial investments deserving of a dedicated maintenance program. Asphalt surfaces can last as long as three decades when properly cared for. To circumvent graying of the surface many asphalt companies recommend applying a sealant every two to three years.
