Even though asphalt is one of the most durable and strongest material choice for driving surfaces, eventually expose to the elements, takes its toll, requiring asphalt repair. Over time, the binding properties of asphalt degrade due to traffic wear, heat, cold, UV rays, frost and thaw cycles, and precipitation. Thus, cracks and potholes develop in the driving surface, much to the bane of motorists.
- To minimize the occurrence of these road hazards, proper maintenance of the asphalt needs to be performed, including routine sealing, repairing cracks, patching holes, and overlaying.
- Sealing -; To rejuvenate a dull asphalt surface an application of two coats of sealant usually suffices. Applying the sealant with a squeegee machine provides the best coverage, whereas spraying, simply coats the surface. To properly seal the asphalt the sealant must penetrate the crevices, cracks, and pores of the asphalt.
- Crack Repairs -; Repairing cracks is an important maintenance practice for two main reasons. First -; water must not be permitted to penetrate the asphalt’s substrate as it will cause cracking and heaving during thaw and freeze cycles. Second -; prevent debris from entering through crevices or cracks which cause further damage during periods of expansion and contraction that occur in thaw and freezing cycles. Before repairs are performed, Coltconcrete.com, will first make sure the area is adequately prepared, before starting. Cleaning the damaged area ensures that the sealant bonds as necessary to edges of the cracks.
- Patching -; Asphalt Repair for larger holes is achieved by patching or filling the space. As with addressing cracks, the hole must be properly cleaned and free of debris before patching can commence. Cold patch is used extensively for smaller holes as it does not require heating and can be placed in a hole with water in it. It is made from recycled asphalt and does not require a curing period, allowing for immediate traffic travel.
- Overlays -; Asphalt surfaces will ultimately need an overlay, even with routine maintenance. An overlay is between 1-1/2 to 2-inches thick, seals small cracks and crevices, and provides a clean, fresh-looking surface.
With routine maintenance and repair, an asphalt surface can easily last 25 – 30 years, before having to be completely redone. It is recommended that asphalt surfaces be resurfaced every two or three years to maintain its appearance and minimize damage later. Routine maintenance results in reduced repair costs down the road as well. You can also connect them on Facebook.
