Caring for any asphalt paving surfaces on your property is an important periodic task, and a few different approaches may be part of it. One common example is asphalt crack sealing – what is this, and why should it be one of your first defenses against damage to your paved surfaces?
At Asphalt Masters, we’re proud to offer the best asphalt crack sealing services available around Ogden, UT, and nearby areas, ensuring your asphalt surfaces are protected from crack expansion, moisture intrusion, and related risks that come from cracked asphalt surfaces. Here are some basics on the science behind asphalt crack expansion, plus some reasons why asphalt crack sealing is an ideal first line of defense if these issues are taking place on your surfaces.
The Science Behind Asphalt Crack Expansion and Moisture Intrusion
Many property owners who utilize asphalt surfaces are well aware that the key risk involved in asphalt surfaces is the potential for cracks to form, which can then lead to a host of additional problems. But why do these cracks form in the first place?
The main culprit behind asphalt crack expansion is moisture intrusion. As water seeps into small openings or imperfections within the surface, it creates an environment where temperature changes and heavy traffic can cause the asphalt to expand and contract, eventually leading to cracks.
This process is known as thermal cracking, and it can be exacerbated by factors such as freeze-thaw cycles or heavy vehicle loads. In addition, UV rays from sunlight can further deteriorate the integrity of the asphalt over time, making it more susceptible to cracking.
Common Asphalt Crack Types
There are several common asphalt crack types you may run into:
- Edge cracking: Some of the most common cracks on asphalt surfaces occur along the edges. Edge cracking typically starts as small, thin cracks and can eventually spread towards the center of the pavement if left untreated.
- Alligator or fatigue cracking: This type of crack resembles the skin of an alligator, with a series of interconnecting cracks forming a pattern that looks like scales. Alligator cracking is caused by repeated traffic loadings and can indicate a weak base or poor drainage.
- Block cracking: These are large, rectangular-shaped cracks that form in a variety of patterns on the surface of the asphalt. They are typically caused by shrinkage of the asphalt layer due to aging or improper construction techniques.
- Slippage cracking: Also known as longitudinal cracking, these are long cracks that run parallel to the direction of traffic. They are caused by a lack of bond between the asphalt layer and the underlying surface.
- Edge cracking: These are cracks that form along the edges of the pavement, usually due to poor compaction at the edges during construction or heavy traffic loads.
- Rutting: This refers to depressions or grooves formed in the wheel tracks of a road. It is caused by repeated traffic loadings and can be exacerbated by inadequate drainage or improper mix design.
These common types of asphalt pavement distresses can not only affect the appearance and smoothness of roads, but also impact their structural integrity and lifespan.
Why Asphalt Crack Sealing is a Vital First Line of Defense
If you’re a property owner or manage a road network, you may wonder why it is necessary to regularly seal asphalt cracks. Here are some key reasons:
- Prevent water infiltration: Sealing cracks in asphalt pavement helps prevent water from seeping into the base and subgrade layers. This can weaken the pavement structure and lead to further cracking and potholes.
- Extend pavement life: By preventing water infiltration and addressing early stage distresses, crack sealing can help extend the lifespan of your asphalt pavement.
- Save money: Regular maintenance like crack sealing is much more cost-effective compared to major repairs or reconstruction of deteriorated pavements.
- Enhance safety: Filling cracks reduces the risk of tripping hazards for pedestrians and prevents damage to vehicles from rough pavement surfaces.
- Improve aesthetics: Cracks can be unsightly, and regular sealing can improve the overall appearance of your pavement.
- Reduce liability: By maintaining your pavement and keeping it safe for pedestrians and vehicles, you also reduce potential liability issues in case of accidents or injuries.
Importance of Seasonal Asphalt Maintenance
In addition to utilizing asphalt crack sealing solutions when cracks arise, seasonal maintenance is also vital for helping prevent damage and prolonging the lifespan of your pavement. By following these tips, you can ensure that your pavement is well-maintained throughout the year:
- Regular sweeping and cleaning: Sweeping away debris and regularly cleaning your pavement helps prevent build-up of materials that can cause damage over time.
- Sealcoating: This process involves applying a protective layer over your pavement to shield it from the elements. It also helps restore the aesthetic appeal of worn-out pavement.
- Fill potholes promptly: Potholes are not only unsightly, but they can also cause serious damage to vehicles. Filling them promptly helps prevent further damage and potential accidents.
- Address drainage issues: Proper drainage is crucial for preventing water from seeping into cracks and causing damage.
