Bitumen spray sealing is a process that is used to seal and protect asphalt surfaces. The process involves spraying a layer of bitumen onto the surface and then using a roller to press it into the asphalt. The bitumen bonds with the asphalt, creating a tough, waterproof coating. It is an effective way to protect your driveway from the damage caused by weathering and traffic.
Spray sealing is a popular choice for homeowners because it’s affordable and easy to maintain. It can help to improve the appearance of your driveway and extend its lifespan.
If you are considering bitumen spray sealing for your home, here is what you need to know.
What is bitumen spray sealing and what are its benefits?
Bitumen is a black or dark brown solid or viscous material that is obtained by the fractional distillation of crude oil. It consists mainly of hydrocarbons and is used as a hardening and waterproofing agent in road construction. Bitumen spray sealing is a process in which bitumen is applied to the surface of a road using a sprayer.
This process helps to bind together the individual particles of sand and gravel, creating a strong and durable surface.
It is a common way to protect roads and driveways in Australia and New Zealand, where the weather can be extreme during certain times of the year.
Bitumen spray sealing has many benefits, including its ability to resist water damage, provide skid resistance, and protect the underlying pavement from the effects of weathering. In addition, bitumen spray sealing is a cost-effective way to maintain roads, making it an ideal solution for both public and private roads.
In Australia, the bitumen base for a lot of public roads is actually made using recycled industrial waste. As such, when it comes to protecting the environment, bitumen roads are significantly better when compared to other road materials like tar.
Common applications for bitumen spray sealing
Bitumen spray sealing is commonly used in the following applications:
- Roads and highways
Bitumen spray sealing is a common way to protect roads and highways from the effects of weathering and traffic. It can help to extend the lifespan of the road surface, and it also provides skid resistance to improve safety.
Bitumen can help to improve the appearance of your driveway and protect it from the elements. Additionally, sealing also has excellent noise-reducing qualities, which is perfect for those who have a relaxing and peaceful atmosphere at home.
- Parking lots
Spray sealing is often used in parking lots to provide a durable surface that can withstand the weight of heavier vehicles. It is also easy to maintain and can help to extend the lifespan of the parking lot pavement.
The process of bitumen spray sealing
Bitumen spray sealing is a simple process that can be completed in a few steps.
- First, the surface to be sprayed must be clean and dry. Any dirt, debris, or moisture must be removed before spraying can begin.
- Next, the bitumen must be heated to the proper temperature. This is typically done with a hot air blower or an infrared heater.
- Once the bitumen is heated, it can be applied to the surface using a sprayer. The amount of bitumen needed will depend on the size of the area to be sprayed.
- After the bitumen has been applied, a roller is used to press it into the surface. This helps to ensure that the bitumen bonds properly with the asphalt.
- Finally, any excess bitumen is removed and the area is left to dry. Depending on the temperature and humidity, this can take anywhere from several hours to a day.
How to get the most out of your bitumen spray sealant
The first step is to make sure that the surface you’re applying the sealant to is clean and dry. Any dirt, oil, or other debris will reduce the bond between the sealant and the surface.
Once you’ve prepped the surface, you’ll want to apply the sealant in thin, even coats. It’s important not to apply too much sealant at once, as this can cause runs and drips.
Finally, make sure to let the sealant dry completely before driving or walking on it. By following these simple steps, you can ensure that your bitumen spray sealant will last for years to come.
Whether you are looking to maintain your driveway or add a touch of style to your property, bitumen spray sealing is an ideal solution. To provide adequate protection for your bitumen/asphalt driveway, be sure to contact a professional contractor to ensure that the job is done correctly.
