Admit it! When you hear someone say asphalt, the first thing that comes to mind is driveways or roads. However, asphalts are flexible enough that it is used for other applications and in different locations. They can be used not just in driveways or roads, but also used in barn floors or ocean floors.
One of the most commonly used asphalt material is HMA or Hot Mixed Asphalt. This is used as a practical solution to flood control, water storage, erosion, and other conservation problems. They are also used as a primary liner in hazardous wastes landfills and sanitary landfills. On the other hand, you can also see asphalt being used in running tracks, race tracks, playgrounds, golf cart paths and bicycle paths, tennis courts, and even in basketball courts. In aquatic applications, they care used in making reservoir liners, sea walls, dikes, groins to prevent soil erosion in beaches, fish hatcheries, and industrial retention ponds. For residential purposes, they are also used to build subdivision roads. In agriculture, they are used in creating barn floors, poultry house floors, cattle feed lots, and greenhouse floors. For industrial purposes, they are used in log yards, work sites, freight yards, and landfill caps.
As you can see, asphalt is not only limited to creating driveways and roads, which are the most common areas where asphalt is being used. Asphalt is made of flexible materials that allow it to be used in different fields. Also, asphalt comes in different types, which allows different applications and functions. Other asphalt types are as follows:
- Porous Asphalt (Permeable Asphalt)
- Double Layered Porous Asphalt
- Soft Asphalt
- Hot Rolled Asphalt
- Stone Mastic Asphalt
- Mastic Asphalt
- Asphalt Concrete (for both ultra thin and very thin layers)
Depending on the application of the asphalt, it can be heated up to 190°C. But warm mix asphalts (WMA) are only heated up to 40°C, while cold mix asphalts don’t need reheating.
Because of the different benefits of using asphalt, it has become the most used paving material all over the world. Many companies opt the use of asphalt in comparison to using concrete as it is more flexible in terms of repair. It is also less costly to maintain and have constructed. Homeowners are also enjoying an environmentally-friendly driveway with porous asphalts. This helps water management in big cities too. But, as you know, asphalt is not limited to residential and commercial uses. They are used in different industries like agriculture and recreation.
