When it comes to maintaining the integrity and longevity of asphalt pavement, crack sealing stands as one of the most vital preventive protocols. While asphalt is appreciated for its durability and resilience, with time and exposure to various environmental elements, it can develop cracks. Left unaddressed, these seemingly insignificant defects can evolve into severe structural damages, augmenting repair costs and decreasing the pavement’s lifespan.

As a solution to these potential problems, crack sealing proposes an effective shield, curbing the deterioration caused by cracking. Yet, understanding the hows and whys of this mechanism is critical to keeping your asphalt surface in its optimal state.

Let’s delve deeper into the world of crack sealing, its benefits, best practices, timing, and some key maintenance tips.

What is Crack Sealing?

Crack sealing, in concept, is a preventative asphalt maintenance process that involves the application of a special sealant into cracks present on the asphalt surface. This sealant is typically a hot-applied, rubberized compound that congeals to form a flexible, water-resistant barrier.

Extending into the cracks, this sealant effectively guards the pavement sub-base against potential threats from water damage, freeze-thaw cycles, and the growth of vegetation in the cracks, thus proactively tackling the root causes of pavement failure.

The Significance of Crack Sealing

The role of asphalt crack sealing in preventative maintenance extends across a range of benefits:

  1. Water Damage Prevention: Water is one of the greatest enemies of asphalt pavement, particularly when it infiltrates through surface cracks to the sub-base. This can cause the material to lose its binding properties, leading to further cracking and irreversible structural damage. Crack sealing acts as a barrier, preventing this water intrusion.
  2. Extended Pavement Lifespan: By tackling cracking issues head-on, crack sealing significantly extends the overall lifespan of your asphalt pavement, ensuring it continues to serve your needs for a longer period.
  3. Economic Efficiency: Though crack sealing comes with an upfront cost, it is a far cheaper alternative to the extensive repairs or complete resurfacing tasks that can result from ignoring cracks.
  4. Preserving Aesthetic Appeal: Regularly sealed pavements tend to retain a more visually pleasing and smooth surface, preserving the aesthetic appeal of your property.

The Ideal Time for Crack Sealing

Promptness plays a key role in effective crack sealing. It is generally recommended to seal a crack as soon as it emerges, regardless of its size. Early treatment reduces the risk of the crack spreading and worsening over time.

Typically, dry and warm conditions are ideal for the application of a crack sealant, due to the physical properties of the sealing compound. Consequently, late spring and early summer months often present the optimal weather window for crack sealing operations.

Crack Sealing Maintenance Tips: A Deeper Dive

Taking proper care of your asphalt pavement calls for meticulousness and prompt action at various stages:

  1. Regular Checks: Make a habit of routinely inspecting your pavements for any signs of cracking. Existing sealed cracks should also be monitored for their condition.
  2. Urgent Sealing: As part of a proactive maintenance plan, cracks should be sealed as soon as they are observed. This urgent action is key to preventing a crack from branching out or becoming larger.
  3. Professional Assistance: While small, hairline cracks can sometimes be dealt with via at-home sealant products, for deeper, wider cracks, professional services ensure that the sealing job is done thoroughly and effectively.
  4. Crack Preparation: A pivotal factor often overlooked is the preparation of cracks before sealing. This usually involves cleaning the cracks of dirt, vegetation, and debris so that the sealant can properly adhere to the asphalt surface.
  5. After-care: A sealed crack does not mean a resolved problem. It’s crucial to revisit the sealed area periodically to ensure that the crack does not reappear or widen.

Going Beyond the Basics: Advanced Maintenance

Besides the basic maintenance protocol, certain advanced strategies can significantly elevate the longevity and efficacy of your crack-sealing procedure:

  1. Right Choice of Sealant: Not all sealants are created equal. The choice of sealant can noticeably influence how effectively and durably it performs. Discussing the selection of a high-quality, rubberized crack sealant with your pavement maintenance expert is advised.
  2. Use of Special Equipment: Professional crack sealing services utilize special equipment like crack cleaning machines and hot-applied crack sealant machines to ensure a thorough and consistent application of sealant.
  3. Pair with Other Preventative Measures: Crack sealing is most effective when used in conjunction with other pavement preventative maintenance strategies like seal coating and regular cleaning. Together, they offer a more comprehensive solution to pavement longevity.


In conclusion, crack sealing forms the cornerstone of effective preventative maintenance for asphalt pavements. It’s a simple, cost-effective strategy that prevents major repair costs, extends the pavement’s lifespan, and maintains its visual appeal.

However, as with most things related to property upkeep, persistence and consistency are key. To maintain the integrity of your pavement, consistent monitoring and prompt addressing of the apparent needs are essential, along with the expert application of the sealing process.
