Understanding Asphalt Cracks

Asphalt pavements are crucial to our daily lives as they are responsible for providing us smooth and durable roads, walkways, and driveways. But as weather conditions, usage, and time take a toll on the structure, the asphalt pavement tends to crack. Cracks can occur in various sizes and shapes, from small hairline cracks to larger fissures and potholes. Looking to expand your understanding of the topic?

The Science Behind Asphalt Crack Filler 1

There are three types of asphalt cracking- transverse, longitudinal, and block cracking. The transverse cracks occur perpendicular to the center lane, while the longitudinal cracks are parallel to the road’s centerline. Block cracking is a series of interconnected cracks that divide the pavement into rectangular blocks.

Types of Asphalt Crack Fillers

Cracks are bound to happen, but it is easier to fix them when they are still small and have not spread further. That’s where asphalt crack fillers come in. The type of asphalt crack filler depends on the severity of the damage caused by the cracks.

For hairline cracks, a simple asphalt emulsion crack filler would do the job. Hot rubberized asphalt crack filler is the most common filler used for cracks that are 1/2 inch or wider. It has a quicker drying time and is more durable than its counterparts. For wider cracks or potholes, a repairing compound or mix needs to be added to the crack filler to fill the damaged area and provide additional stability.

The Science Behind Asphalt Crack Filler

Asphalt crack fillers are composed of two main components – a binding agent and a filler material. The binding agent is responsible for holding the filler material together. The filler material is the substance that fills the cracks. These materials are designed to work together to maintain the pavement’s structural integrity and prevent further damage.

The binding agent is made of one of two types of asphalt- asphalt cement or refined tar. The asphalt cement is a petroleum-based substance that is commonly used in the construction of asphalt pavements. The refined tar, which originates from coal, is the other key binding agent for crack filler. It is better at resisting damage caused by oil and gas spills, making it ideal for parking lots and garages.

The filler material is an aggregate that provides the necessary support and density to maintain the pavement’s structure. Most asphalt filler material is mixed with a polymer that gives it more durability and flexibility. The polymer helps the filler material to withstand temperature changes, foot and vehicle traffic, and other environmental factors.

Benefits of Using Asphalt Crack Fillers

Asphalt crack fillers are cost and time-effective. Fixing cracks before they turn into larger fissures or potholes saves an immense amount of money in the long-run. It is also safer for both pedestrians and drivers as it eliminates potential tripping hazards and provides a smoother ride. Crack filling helps prevent further damage to the asphalt pavement, extending its lifespan, and avoiding costly repairs.

Crack filling is also an eco-friendly process. It allows for the reuse of existing materials, reducing the amount of waste generated from repairing pavements. It also helps to minimize the carbon footprint associated with re-construction.


Asphalt crack fillers are an essential component in maintaining pavement infrastructure. They are not only cost and time-effective but also provide a safer and smoother ride. With the use of polymer-aggregate binders, asphalt fillers offer increased durability and flexibility, ensuring that the pavement’s structure remains intact.

By using asphalt crack fillers, one can save money, reduce waste, and promote sustainability. Want to know more about the subject? Get to know this complementary resource, uncover additional and valuable information that will enrich your understanding of the topic discussed.
