Does Your Parking Lot Needs Repair? Asphalt Paving Damages to Look For

Written by Dave on . Posted in Uncategorized

Asphalt paving gives your driveway or parking lot an appealing look. And while it’s quick to install, this kind of paving lasts for a long time if it’s well established and maintained. But poor paving causes losses, as you’ll have to perform repairs to get your parking lot or driveway paving looking good again. In today’s post, we’ll discuss some common residential asphalt paving damages and possible remedial measures to improve your paving.

 

Transverse asphalt paving cracks

 

Transverse asphalt paving cracks form gaps that are perpendicular to your pavement or car park’s centerline. These crack-related damages occur when there are problems with the paving’s underlying layer.

 

Alligator cracking

 

Alligator cracking is an asphalt paving problem that results from overloading. This damage may occur when the paving’s sub-base is not well installed or when the pavement is too thin.

 

Longitudinal cracking

 

Longitudinal cracks on asphalt paving run parallel to your paving’s centerline. These asphalt paving problems are a result of poor longitudinal joint building.

 

Slippage cracks

 

If the bond between pavement layers is poor or the asphalt mix is weak, then you may end up with slippage cracks. Slippage cracks can be differentiated from other asphalt paving damages because they appear more like stretch marks.

 

Block cracking

 

Block cracking of asphalt paving occurs when the interconnected paving cracks form rectangular shapes on your driveway or parking lot’s pavement. Such damages occur when your asphalt binder expands and shrinks during the changing of temperature cycles. This problem often happens when the used asphalt mix is too dry when paving. Ensure that you hire a qualified asphalt paving contractor to prevent such issues.

 

Edge cracks

 

As the name indicates, edge cracks are cracks that show up near the outer edges of your parking lot or pavement. Failure to build a durable side for your asphalt paving and the growth of vegetation are the leading causes of edge cracks.

 

Stripping

 

Asphalt stripping occurs when the adhesion between the aggregate and the asphalt layer becomes weak. This problem causes dislodging, which is a significant cause of cracks in asphalt paving.

 

Potholes

 

Asphalt paving potholes are a result of overloading and wear and tear caused by the vagaries of weather. But they are worsened by heavy traffic on the paving. Most potholes are sustained by the freezing water in the melting and freezing cycle that occurs in the cold and warm seasons. Such freezing and melting cycles of water within the asphalt base can weaken the paving. Preventative maintenance is the best way to solve such problems.

 

Base failure

 

Base failures are often an outcome of poor drainage in your paving. Installation errors, a lack of support, and lots of weight concentration in one area can also cause base failures. But correcting such a problem can be costly because you’ll need to remove the entire top surface layer.

 

Depressions

 

Depressions occur in paving areas where some part of the pavement surface is below the elevation of the more considerable part of the pavement. It’s akin to a sunken area on a flat surface. The problem is often caused by poor driveway paving services, in most cases. Such sunken depressions hold water during the rainy and wet seasons, and this water causes further damage to the paving.

 

Proper building of asphalt paving leads to the creation of long-lasting pavements. Asphalt damages are common, but most of them can be corrected to create durable and robust asphalt paving for car parks and driveways. Most asphalt paving damages can be avoided if your contractor adheres to the strict rules of proper asphalt paving installation.

 

Smooth asphalt paving lasts longer than any pavement that is not even, and its lifespan can be extended by 10% to 25%. Such asphalt paving that is set in an even way reduces the maintenance and repair costs. As such, it’s advisable to hire the best contractor to get the best asphalt paving installation that will last and save you money when it comes to asphalt parking lot maintenance and repairs.
