Thanks to its durability, ease of maintenance, and cost-effectiveness, asphalt is a popular choice for paving surfaces like roads, driveways, and parking lots. Many property owners have questions about asphalt and want to know more about how to care for it properly. In this blog post, we’ll answer some FAQs to help you be able to make informed decisions about your property.
FAQ #1: What Is Asphalt Made Of?
Asphalt is made of aggregates such as gravel, sand, and crushed stone and a binder—typically bitumen, a byproduct of crude oil refining. The binder holds the aggregates together, creating a flexible yet durable material. Asphalt’s specific composition can be adjusted to suit the needs of different projects.
FAQ #2: How Long Does Asphalt Last?
Typically, asphalt lasts 15 to 20 years; however, its lifespan can vary based on several factors, including climate, usage, and the level of maintenance it receives. Regular maintenance like crack filling and sealing can significantly extend the longevity of your asphalt pavement, ensuring it stays safe and functional for as long as possible.
FAQ #3: What is the Difference Between Asphalt and Concrete?
While concrete and asphalt are both popular options for pavement, they have significant differences. Asphalt is more flexible than rigid concrete, allowing it to better handle temperature changes. It’s also generally cheaper and quicker to install. Concrete lasts longer; however, it requires more time to set and cure. Neither material is better than the other; they each have their own advantages, making them suitable for different projects.
FAQ #4: When Was Asphalt Invented?
Asphalt has been used for much longer than you might think. The first recorded use of natural asphalt deposits as a road-building material dates back to around 625 B.C. in ancient Babylon. The first true asphalt pavement was laid in Paris, France, in 1858. The modern technology quickly spread to the United States, where the country’s first asphalt road was constructed in New Jersey in 1870.
FAQ #5: Where Is Asphalt Made?
Asphalt is produced in specialized plants where aggregates like gravel, sand, and crushed stone are combined with a binder (usually bitumen). Asphalt plants are found all around the world, providing materials for various construction and maintenance applications. The precise production process ensures the mixture is consistent and meets strict quality standards.
FAQ #6: Will Asphalt Burn?
Asphalt is not flammable. However, it can melt and emit fumes if it’s exposed to extremely high temperatures, such as those found in a fire. Its inflammability makes it a safe paving material, as it does not pose a significant fire hazard.
FAQ #7: What’s the Difference Between Asphalt and Tar?
Asphalt is derived from refined petroleum and is primarily used for driveways and roads. Tar, on the other hand, is made from wood and coal and is used for roofing and waterproofing. When it comes to environmental degradation, asphalt is more durable than tar.
FAQ #8: How Can I Prevent Cracks in My Asphalt Pavement?
Proper installation and regular maintenance are the keys to preventing cracks. A strong base, good drainage, and high-quality materials are especially crucial. Additionally, resealing the asphalt pavement as needed and filling cracks promptly can prevent further damage.
FAQ #9: How Often Should Asphalt Be Sealed?
We recommend sealing asphalt surfaces every two to three years. Sealcoating helps protect the pavement from chemical exposure, moisture, and UV rays, extending its lifespan and maintaining its pristine appearance. For maximum protection against wear and tear, high-traffic areas may require more frequent sealing.
FAQ #10: What Is the Process of Resurfacing Asphalt?
The resurfacing process begins with cleaning and repairing the existing asphalt surface, followed by applying a tack coat to support proper adhesion. Then, a new layer of asphalt is laid on top and compacted. Asphalt resurfacing is a cost-effective alternative to replacement and can extend the pavement’s life by several years or more.
