Asphalt paving is exposed to extreme weather elements such as rain and sunlight, not to mention the heavy traffic from vehicles and pedestrians. As a result, it becomes brittle with age and can easily get damaged. Even with proper maintenance, wear and tear are inevitable, and the asphalt will need to be replaced one way or another. Below are a few pointers to help you determine when to replace your asphalt.
Large Potholes
Potholes are a likely occurrence in many asphalt pavements. Small ones are easy to repair and fill up, while larger ones indicate it is time to replace the asphalt. When left unattended, water can seep through the exposed layers in the potholes and damage the base of the asphalt paving compromising structural integrity. Likewise, these exposed potholes are hazardous and can cause accidents for which the business owner can be sued.
Issues With The Drainage
Asphalt pavements are usually constructed at an angle to allow water to drain off. Any signs of pooling water on the asphalt indicate that the paving is warped. This water can seep through the crack and compromise the structural integrity of the base. Also, in areas that have winters, the trapped water beneath the surface can undergo a freeze and thaw cycle, which can further cause damage to the asphalt.
Cracked Surface
Small cracks on the surface of the asphalt can be fixed temporarily with a sealant. This prevents the cracks from spreading and causing further damage. However, a distinct pattern of cracks is an excellent indicator of an issue with the pavement foundation. The best way to combat this is to replace the asphalt entirely from the base up. However, an experienced commercial asphalt paving contractor can offer advice on whether to repair the asphalt or replace it completely.
Discoloration Of The Surface
Exposure to prolonged sunlight can be damaging to asphalt paving. It can cause the asphalt to turn from a shiny black to a dull gray. This color change indicates that the structural integrity of the asphalt might be compromised. Applying a seal coating at the final stage of installation can help prolong the lifespan of the asphalt. Regular inspection and maintenance can also help towards increasing its lifespan.
Deciding whether or not your asphalt needs to be replaced is a huge task. Any of these signs can help guide you towards making the decision. Keep in mind that the longer you postpone the replacement, the larger the problem becomes. A commercial paving contractor can offer advice to help you make the right decision.
