How Chip Sealing Extends The Life Of The Pavement

Chip sealing is a pavement surface treatment that involves the application of a coating of asphalt to seal the surface and then a layer of aggregate chip is embedded in the asphalt. And this treatment process is necessary because it extends the life of the pavement, helps prevent water damage, and improves traction.

There are several key steps involved in the chip sealing process, including cleaning the surface to be treated, applying the asphalt and aggregate coating, embedding the aggregate into the asphalt layer, and compacting and rolling the pavement.

So how chip sealing extends the life of the pavement? If you want to know more, we suggest you continue reading as we’re going to tackle this topic in today’s post.

 

How It Is Done

chip sealing benefits

The chip sealing process begins with the cleaning of the surface to be treated. This is an important step, as any dirt or debris that remains on the pavement can interfere with the adhesion of the asphalt coating. After cleaning, a layer of hot asphalt is then applied to the surface and spread evenly across the entire area.

Next, a layer of aggregate chips ranging in size from 1/8” to 1/4″ is embedded into the asphalt. This step ensures that the pavement will have a strong, durable surface that provides excellent traction for vehicles, cyclists, and pedestrians alike. Finally, the pavement is compacted and rolled in order to press the aggregate chips firmly into place and further improve its durability.

While chip sealing may seem like a simple process, it is an important one that helps to extend the life of the pavement and keep it looking its best. Whether you’re a driver or pedestrian, this treatment process can help keep your roads safe and durable for years to come.

 

Different Types Of Chip Seals Used For Pavement Preservation

There are different types of chip seals used, and each has its own benefits and drawbacks.

The most common type of chip seal is the asphalt-emulsion chip seal. This type uses an emulsion solution as a binding agent for the chip seal, which helps to create a strong and durable surface. Another type is the latex-modified bitumen chip seal, which uses a modified bitumen binder instead of an asphalt emulsion. This type may be more suitable in cold climates or where there is high traffic volume.

Regardless of the type of chip seal used, they all have the same basic process and that is a layer of asphalt or bitumen binder is applied to the pavement. Then, a layer of aggregate chips is spread over the binder to be followed by using a roller to press the chips into the binder.

 

How Long Will A Chip Seal Last Before Re-application

Chip sealing protects the pavement from weather and traffic damage. So how long does chip sealing last before the next application? This will vary depending on the type of chip seal used, the climate, and the volume of traffic. Generally, chip seals should last around 3 to 5 years before they need to be reapplied.

 

Final Word

Chip seal is a popular pavement preservation treatment because it is relatively inexpensive and easy to install. However, it is not suitable for all types of pavements. In particular, chip sealing should not be used on concrete or asphalt pavements that are in poor condition. It is also important to ensure that the pavement is cleaned and repaired before the chip seal is applied.

Overall, chip sealing is a beneficial treatment that can extend the life of the pavement. However, it is important to choose the right type of chip seal for the climate and traffic conditions. Also, be sure to clean and repair the pavement before applying the chip seal.
