The Importance of Asphalt Sealing Techniques
Asphalt is a popular material for building pavements due to its affordability, durability, and versatility. However, its porous nature makes it vulnerable to wear and tear from constant exposure to weather extremes, UV radiation, chemicals, and heavy traffic. Over time, asphalt begins to fade, crack, and degrade, leading to potholes, bumps, and other forms of damage that compromise the safety and aesthetics of the pavement.

Asphalt sealing is the process of applying a protective coating to the surface of the pavement to prevent water penetration, oxidation, and other forms of damage. Asphalt sealing can extend the life of the pavement, enhance its appearance, and improve the driving experience for motorists. However, not all sealing techniques are created equal and choosing the right one can make a significant difference in the outcome.
The Best Asphalt Sealing Techniques
1. Crack Sealing
Cracks are one of the most common forms of pavement damage, especially in cold climates where freeze-thaw cycles cause the expansion and contraction of the asphalt. If left unrepaired, cracks can widen, become potholes, and compromise the structural integrity of the pavement. Crack sealing is the process of filling and sealing the cracks with a hot or cold rubberized sealant that adheres to the asphalt and prevents water from seeping in.
The best time to perform crack sealing is in the fall, before winter arrives, as the sealant needs adequate time to cure and dry. Crack sealing should not be done in rainy or wet conditions, as it can affect the adhesion of the sealant to the pavement. In addition, crack sealing should only be done on cracks that are less than 1/4 inch wide, as wider cracks may require other repair methods such as patching or resurfacing.
2. Sealcoating
Sealcoating is the process of applying a thin layer of asphalt emulsion or coal tar pitch to the surface of the pavement to protect it from water, oils, and UV radiation. Sealcoating also enhances the color and texture of the pavement, making it appear like new. Sealcoating should be done every 3-5 years, depending on the traffic level and weather conditions.
Sealcoating can be done by spraying, brushing, or squeegeeing the asphalt emulsion or coal tar pitch onto the pavement. However, it is important to use high-quality materials and equipment to ensure a consistent and uniform coverage. In addition, sealcoating should not be done in rainy or humid conditions, as the moisture can affect the bonding and drying of the coating. Sealcoating should not be done on wet or dirty pavement, as the dirt and debris can interfere with the adhesion of the coating.
3. Slurry Sealing
Slurry sealing is a mix of fine aggregate, asphalt emulsion, water, and additives that is applied to the surface of the pavement to fill in small cracks and imperfections, improve traction, and restore the surface appearance. Slurry sealing is ideal for pavements that have moderate wear and tear and are in need of a cost-effective and quick solution.
Slurry sealing should be done in dry weather conditions, as the emulsion needs to cure and dry before traffic can resume. Slurry sealing is typically done by spraying the mixture onto the pavement and spreading it evenly with a squeegee or a drag box. It is important to perform a thorough cleaning of the pavement before slurry sealing to remove any loose debris or vegetation that can interfere with the adhesion of the mixture.
4. Microsurfacing
Microsurfacing is a mixture of polymer-modified asphalt emulsion, mineral aggregate, water, and additives that is applied to the surface of the pavement to improve its skid resistance, durability, and appearance. Microsurfacing is ideal for pavements that have moderate to severe wear and tear and require a long-lasting and high-performance solution.
Microsurfacing should be done in dry weather conditions, as the emulsion needs to cure and dry before traffic can resume. Microsurfacing is typically done by spraying the mixture onto the pavement and spreading it evenly with a specialized machine. Microsurfacing requires precise monitoring and adjusting of the mixture components, as well as thorough surface preparation to ensure maximum bonding and adhesion.
