Asphalt is an incredibly versatile material. And there are good reasons why it’s used in such a variety of ways – not only is it durable and typically made from recycled material; it’s also a relatively inexpensive choice for many paving projects. But that’s not all: asphalt is remarkably long-lasting. In fact, many asphalt surfaces can last 15 to 20 years or longer if they’re cared for properly.
There are several different types of asphalt that a paving contractor may use, including the following:
- Hot mix – Just as the name implies, this type of asphalt – which is a combination of stone, sand, gravel, and a binding agent – is heated to about 300°F before it’s poured.
- Warm mix – This type of asphalt doesn’t cool as quickly as hot mix does, and it contains emulsions that make it a little easier to spread and pour.
- Cold mix – The most affordable type of asphalt is cold mix, which requires no heat at all. Cold mix asphalt is typically used to repair cracks and other damage in already-paved surfaces.
- Cutback – This type of asphalt is a combination of asphalt cement and petroleum solvent, and is used primarily for spray applications.
- Mastic – This formula is extremely dense and is typically used for waterproofing.
Asphalt Applications
What follows are some of the most common uses for asphalt, some of which may surprise you!
- Roadways – Believe it or not, approximately 94 percent of the roadways in the US are paved with asphalt!
- Parking lots – Once again, asphalt is the most common material used for parking lots. In fact, about 90 percent of the parking space in the US are paved with asphalt.
- Walking paths – Pathways are another common use for asphalt, from city parks to national parks and much more.
- Driveways – Due most likely to its durability and relatively low cost, asphalt is becoming increasingly common for residential driveways.
- Waterproofing – The most fluid form of asphalt is often used as an effective waterproofing agent for walls and rooftops under construction.
- Other projects – Asphalt is used for a large variety of construction projects, such as playgrounds, parks, dams, reservoirs and retention ponds.
Considering its durability, strength, and relatively low cost, it’s no wonder that asphalt is used in such a variety of ways. To find out more about this popular paving material, and to learn if asphalt is the best choice for your upcoming project, contact a local, reputable paving contractor.
