Different Types of Crack Sealers for Asphalt 1

Purpose and Importance of Crack Sealers

Crack sealers are essential in maintaining the durability and longevity of asphalt surfaces. They are specifically designed to prevent water infiltration and protect the underlying layers of asphalt from damage. Cracks in asphalt can occur due to various factors such as weather conditions, traffic load, and aging. If left untreated, these cracks can expand and accelerate pavement deterioration, leading to costly repairs or even the need for complete resurfacing. Crack sealers play a vital role in preventing further damage and extending the lifespan of asphalt surfaces.

Hot Pour Crack Sealers

Hot pour crack sealers are one of the most commonly used types of crack sealers for asphalt. They are made of a mixture of asphalt binder, fillers, and modifiers that are heated to a specific temperature before application. This type of crack sealer is particularly effective in filling and sealing larger cracks and joints. The hot pour crack sealer is melted in a specialized applicator, usually a kettle or melter, and then poured directly into the cracks. It quickly cools and solidifies, forming a flexible and waterproof seal that prevents moisture from penetrating the asphalt surface.

Cold Applied Crack Sealers

Cold applied crack sealers, also known as cold pour crack sealers, are an alternative option to hot pour crack sealers. These crack sealers are premixed and do not require heating before application. They are typically supplied in a ready-to-use form, making them convenient and easy to apply. Cold applied crack sealers can be used for both small and large cracks, providing adequate protection against water infiltration and preventing further deterioration. They are suitable for minor repairs and maintenance projects and offer a cost-effective solution for crack sealing.

Elastomeric Crack Sealers

Elastomeric crack sealers are a type of flexible crack sealer that can accommodate the movement and expansion of cracks in asphalt. They are formulated with elastomeric additives, such as rubberized polymers, that enhance their elasticity and durability. Elastomeric crack sealers have excellent elongation properties, allowing them to stretch and recover without cracking or breaking when subjected to temperature fluctuations and pavement movements. This type of crack sealer provides a long-lasting seal that effectively prevents water intrusion and offers superior resistance to environmental factors.

Routing and Sealing Crack Sealers

Routing and sealing crack sealers are specialized crack sealing techniques that involve routing or cutting the cracks before filling them with sealer. This method is particularly effective for larger cracks and heavily damaged areas. The crack is widened and cleaned using a mechanical router or a diamond-blade saw, creating a reservoir for the sealant. Once the crack is prepared, a hot pour or cold applied crack sealer is applied to fill the routed crack. This method ensures proper adhesion and maximum effectiveness of the crack sealer, enhancing its longevity and performance.

Conclusion

Crack sealers are essential in maintaining the integrity and performance of asphalt surfaces. By filling and sealing cracks, they prevent water infiltration and protect the underlying layers from further damage. Hot pour crack sealers, cold applied crack sealers, elastomeric crack sealers, and routing and sealing crack sealers are different types of crack sealers available in the market. Each type has its own advantages and suitability for specific applications. Choosing the right crack sealer depends on factors such as crack size, pavement condition, and budget. By investing in regular crack sealing and maintenance, asphalt surfaces can be preserved and kept in optimal condition for years to come.
