5 Ways to Tell if Your Parking Lot Needs to Be Repaved

Parking lots are made to last longer. However, they do not last forever. A parking lot made of concrete lasts up to 25 years while that made of asphalt lasts for 20 years. It reaches a time when you have to repave your parking lot. But how do you determine it is the right time for repaving. Here five are ways to tell.

Presence of Cracks

The presence of cracks in your parking lot is a number one sign that it needs repaving. Cracks usually form when the parking lot is nearing the end of its lifespan. However, sometimes the cracks may develop prematurely when chemicals penetrate the surface and water seeps in. There are different conditions that can lead to cracks in the pavement. They include shrinkage, widening, edging, slippage and reflection. When evaluating cracks, you need to determine how wide, deep and long they are. The more wide, deep and long a crack is, the more the parking lot needs to be repaved.

Potholes

Potholes develop on a parking lot due to repeated expansion and contraction of the concrete or asphalt. The repeated expansion and contraction may also affect the ground underneath the pavement, leading to further damage. If the potholes are small and few, you can fill them up with concrete or asphalt. If they are large and widespread, repaving might be the way to go.

Drainage Problems

Drainage plays a major role in the lifespan of your parking lot. The presence of drainage issues signifies that it is time to fix the problem before it becomes worse. The pooling water or runoff that accumulates in the middle of the parking lot may cause the surface to settle and become weak with time. This can lead to deep and wide cracks. If you experience significant drainage issues, it is time to do repaving to lengthen the life of your parking lot.

Weathered Appearance

Parking lots fade over time, as the UV rays from the sun penetrate the concrete and the surface becomes oxidized. The UV rays and the oxygen can weaken the surface, resulting in serious cracks. If you notice the pavement is beginning to change its appearance, then, it may be time to perform some serious paving.

Raveling

Raveling occurs when the aggregate particles of the pavement dislodge from the surface. It is as a result of the oxidation of the asphalt binder. The oxidized binder weakens and loses its ability to hold the aggregates together. Raveling gives the surface of your parking lot a rough texture. It is possible to correct the problem with a sealant but only if it is minor. A significant raveling requires repaving. Make sure you get someone who is well trained in pavement repair to work on your parking lot.
