5 Types Of Pavement Failure No Property Manager Wants On Their Parking Lots

One of the most common types of pavement failure on parking lots is cracking. This can be caused by several factors, such as weather conditions and heavy traffic. Lethbridge is still dealing which can further aggravate asphalt damage.

When cracking occurs, it can lead to pieces of the pavement breaking off, which can be dangerous for drivers and pedestrians. These are the kind of concerns that might make it hard for parking lot property managers to sleep at night as they wonder how to budget the next repair run.

Although the list of pavement failures is extensive in our experiential knowledge, some types are very common to parking lots. Here are a few examples of asphalt damage that no property manager wants on their lot:

1. Cracked Asphalt

Alligatored asphalt is the result of dehydrated asphalt. It starts from continuous exposure to freeze-thaw cycles, water intrusion, & UV degradation. Dehydration does not mean a lack of moisture because asphalt is bituminous-derived and requires oils to retain its elasticity.

If the asphalt were aged, grey, & dried out without cracking, the simplest solution would be to deploy asphalt rejuvenators. But, if cracking has occurred on your parking lot, you need crack-filling or maybe an overlay.

2. Raveling Surface

UV degradation is a cruel reality of all constructed features, including parking lots. When seal coats weather out, the underlying asphalt is exposed to the sun and starts to break down & chip away. Other more obscure reasons may have to do with improper asphalt mix & compaction at the time of installation.

Solutions include overlays and properly deployed binding coats.

3. Ruts & Depressions

Insufficient parking lot subgrade preparation, improper asphalt compaction, and then failure to restrict heavy vehicles from entering the lot can result in depressions. If there is much traffic in the lot, ruts can develop from wear & tear. This is why it is strongly advised that parking lot managers enlist the services of a paving professional renowned in the local community to take on proper asphalt installation.

Full-depth HMA patch is the only suitable solution for pavement failures stemming from flawed asphalt & sub-base design.

4. Potholes

If the freeze-thaw cycle & subsequent alligatoring are ignored too long, the next step is pothole formation. When they start collecting ice & water, the damage spreads. The presence of cracks alone is enough to put your parking lot in violation of ADA compliance & regional compliance codes, but having potholes is potentially lethal & distressing to the disabled & elderly before you even get flagged.

Potholes need prompt patching to protect visitors from any accidents. Besides, they heavily impact the visual appeal of parking lots, reducing visitor ship & inciting dissatisfaction.

5. Faded Stripes

Although not exactly a pavement failure for asphalt parking lots, when you have an eroded seal coat or raveling pavement, the stripes for traffic control & ADA compliance also wear out. That can confuse parking lot users, and the loose gravel chips can create trip hazards too.

Your best bet is to go for an asphalt texturing & surfacing solution and then reapply the stripes.
