Tips & Advice
What causes rutting?
Rutting occurs in the wheel tracks of a road and is generally seen when the asphalt isn't thick enough to support traffic.
Edge cracks are caused by weak edges. When there isn't enough support at the edge, the road will begin to stress and crack over time.
Depressions, are caused when the pavement isn't as deep in one area, or the land on which the road was laid is uneven. A slight depression can be fixed with another layer of asphalt.
What are transverse cracks?
Transverse cracks run perpendicular to the road's centerline, and can be caused by poor joint construction. Seasonal or daily temperature changes can also contribute to transverse cracks.
What are longitudinal cracks?
Longitudinal cracks are parallel to the road's centerline or the direction the driveway or parking lot was paved. They are caused by poor joint construction or simply aging pavement.
What are joint reflection cracks?
Joints are usually the weakest part of a paving job, and inadequate joint construction can eventually lead to cracks. Joint reflection cracks occur on asphalt surfaces that are laid over concrete surfaces.
What causes alligator cracks and potholes in asphalt?
These scaly-looking cracks that run throughout a portion of a road are caused when the asphalt wasn't provided enough support or drainage. Over time, they can deteriorate until they become potholes. Prevent alligator cracks by making sure the base layer is strong enough. If you begin to notice alligator cracks or potholes, only a full-depth patch can remedy them.
What are some common issues and hazards with asphalt?
When asphalt gets old, or if the wrong type of asphalt was used for a particular job, certain types of defects can begin to show, such as alligator cracks and potholes; longitudinal, transverse, and joint reflection cracks; bird baths, edge cracks, and rutting.
What can affect the cost of a paving job?
The size of the job will make a difference, as well as necessary materials. If your driveway needs to be leveled out or if there are drainage issues, your quote could increase. Talk about the grade of asphalt and any challenges your job requires - these could also increase the cost. One red flag is being asked for a down payment, it shouldn't require one. If a quote seems really low, find out why. Check for hidden fees you didn't discuss during the initial conversation.
What questions should I ask when choosing a paving contractor?
Are you insured?
- Is your asphalt recycled?
- What type of equipment do you use?
- How much will it cost?
- How many people will work on my project?
- Do you have references I can call?
Bad pavement jobs can result in pooling rainwater and premature cracking, so you need to choose a paving contractor who can deliver a durable, professional-looking surface.
