Understanding the Different Types of Asphalt Crack Fillers 1

Using Asphalt Crack Fillers to Extend the Lifespan of Your Pavement

Pavement surfaces, such as roads, driveways, and parking lots, are subjected to a lot of wear and tear over time. One common issue that arises is the formation of cracks on the surface. Cracks not only compromise the aesthetics of the pavement but also pose a safety hazard and can lead to further damage if left untreated. Asphalt crack fillers are an essential tool in maintaining the integrity of pavement surfaces. In this article, we will explore the different types of crack fillers available and understand their unique properties and applications.

1. Hot Pour Crack Fillers

Hot pour crack fillers are popular among professionals for repairing cracks in asphalt pavement. These fillers are applied by heating them to a high temperature and then pouring the molten filler into the cracks. The heat helps the filler penetrate deep into the cracks, providing a strong and long-lasting repair.

Hot pour crack fillers are typically made of a rubberized asphalt compound. This material has excellent flexibility, allowing it to expand and contract with temperature changes, preventing the cracks from reappearing. The rubberized nature of the filler also enhances its ability to bond with the surrounding asphalt, forming a tight seal.

2. Cold Pour Crack Fillers

Cold pour crack fillers are a popular choice for DIY enthusiasts and property owners looking for a convenient and cost-effective crack repair solution. Unlike hot pour fillers, which require special equipment and expertise, cold pour fillers can be applied directly from the container.

These fillers are formulated with polymers that remain flexible even at low temperatures. This flexibility allows them to accommodate movement without cracking, ensuring a durable repair. Cold pour crack fillers are often used for smaller cracks and are available in ready-to-use containers, making them ideal for small-scale repairs.

3. Asphalt Emulsion Crack Fillers

Asphalt emulsion crack fillers are another common option for repairing cracks in asphalt pavement. These fillers are made by combining asphalt binder with water and an emulsifying agent. The resulting mixture can be easily poured or applied using a squeegee.

Emulsion crack fillers offer excellent adhesion to the surrounding pavement, ensuring a strong bond. They also have good flexibility and elasticity, allowing them to withstand temperature fluctuations and movement without cracking. Additionally, the water content in these fillers helps cool down the mixture, making them safe and convenient to use.

4. Flexible Crack Fillers

Flexible crack fillers are designed to accommodate significant movement and deformation without cracking or breaking. These fillers are commonly used in areas where the pavement is subjected to heavy traffic loads or high levels of temperature fluctuations.

Flexible crack fillers are typically made of specialized polymers that offer superior elasticity. They can stretch and compress as the pavement expands and contracts, preventing the formation of new cracks. The flexibility of these fillers ensures a long-lasting repair, even in demanding conditions.


Choosing the right asphalt crack filler is crucial for maintaining the integrity and longevity of your pavement. Hot pour crack fillers provide a strong and durable repair, ideal for professional use. Cold pour fillers offer convenience and cost-effectiveness, making them a popular choice for small-scale repairs. Asphalt emulsion crack fillers provide excellent adhesion and are easy to use. Lastly, flexible crack fillers are designed for areas with high movement and traffic.

By understanding the different types of crack fillers and their unique properties, you can make an informed decision and ensure a successful repair that extends the lifespan of your asphalt pavement.
