What is Porous Asphalt Pavement?

porous asphalt pavement

Porous Asphalt Pavement is a type of Asphalt. Asphalt is a black, sticky substance that occurs naturally but can also be refined from crude oil. Blacktop, also referred to as asphalt concrete, is a mixture of sand, stone, and gravel used in the construction of roads and pavements. Asphalt pavement is the most preferred way of building roads as it is cheap, durable, and doesn’t take much time to complete. Actually, more than 90 percent of the paved surface (roads, parking lots, driveways, airport runways, etc.) in the United States are made of asphalt pavement. Asphalt pavement’s superiority to its alternatives is exhibited by its quiet, smooth ride, environmental friendliness, and speed of construction.

Typically, pavements are designed to allow runoff water — from rainfall or elsewhere — to flow along the surface and drain into a nearby ditch or water catchment area. Porous asphalt pavement is a type of pavement structure specially designed to allow runoff water to seep through the surface into an underlying recharge bed where it will gradually percolate into the soil.

What Does A Porous Asphalt Pavement Look Like?

Surfaces made from porous asphalt are almost identical to those made from standard asphalt. The only difference is that porous asphalt pavement is a little coarser, but the surface is still smooth enough to meet the requirements of the ADA (Americans with Disabilities Act). It’s actually very hard for a regular person to tell the difference.

What Is The Lifespan Of A Porous Asphalt Pavement?

What is the lifespan of a porous asphalt pavement and most importantly, for how long will the surface remain porous? This is a question that many people considering porous asphalt find themselves asking. The answer to both questions is a very long time. Porous asphalt surfaces are built to last for decades. In most cases, a porous asphalt pavement will be showing little to no cracks/potholes at all twenty years after construction. Their ability to retain water lasts even longer.

The use of porous asphalt in the construction of pavements has been applauded by government agencies around the world as an alternative practice to runoff control and storm water management. In the United States, the National Environmental Protection Agency (NEMA) recognizes porous asphalt as a sustainable way of protecting streams, replenishing aquifers, and promoting infiltration thus reducing runoff to conserve rainwater.

Modern Paving Technology

Modern Paving Technology - A&M Paving

When it comes to the construction of pavements, driveways, and parking lots, there is a broad range of modern paving technology that make the job easier for workers. There are, too, a lot of paving surfaces that domestic and commercial property owners can choose from. Concrete and asphalt are the most popular paving materials in this regard. Each of these construction material has its own unique strengths and shortcomings. If you are looking to pave your driveway, pavements, or parking lot, it is imperative that you do your due diligence before deciding on the most appropriate material to meet your specific needs. Below is a rundown of benefits you can expect if you choose to go for asphalt paving for your business or home.

1. Durability

Durability is a paramount factor to consider when it comes to choice of pavement. Although asphalt pavement will certainly need regular maintenance, proper maintenance will ensure that it looks new and aesthetically appealing for an extended period. When properly maintained, asphalt pavements can last more than twenty years. Besides, replacing asphalt pavement is quite affordable owing to the fact that the middle and the bottom layers are considered permanent, and therefore, only the top layer needs replacing. This makes asphalt paving more efficient in the long run compared to other materials such as concrete, for example.

2. Save Time and Money

The use of modern paving technology for asphalt surfaces has made it less expensive and quicker to install than ever. Concrete pavements, however, can take more than twice as much time to construct and cure. On the other hand, asphalt pavement can be laid within a few hours or days, depending on the size of the given project. While concrete pavement can take up to seven days to cure, asphalt is ready for use in just two days after installation.

3. Environmental friendliness

If you are concerned about conservation, then asphalt paving is the right choice for you. Asphalt is better for the environment because it can be recycled. Old asphalt can be ground and be reused in the construction of new pavements. Besides, the permeability of porous asphalt makes it better for drainage compared to concrete and other paving materials.

In a nutshell, it is apparent that asphalt, along with modern paving technology, is great because it is not only durable, but also efficient and environmentally-friendly.
