Why Do Companies Recycle Asphalt?
As most people know, asphalt is a major part of the construction of roads, as well as some driveways. Known also as bitumen the asphalt helps to bind together all of the aggregate particles that go into the formation of asphalt concrete. In addition to being useful for road construction, asphalt can play a large role in roofing and waterproofing.
Benefits of Recycling Asphalt
One of the biggest benefits comes in the way of savings. Governments are huge buyers of asphalt because they are responsible for maintaining the roadways. By using recycled asphalt, they are able to save millions of dollars of the taxpayer’s money. Recycling is also helpful in preserving dwindling resources. In some cases, it’s possible to recycle the asphalt onsite, which can save quite a bit of time, as well as save more money.
How Does the Asphalt Recycling Work?
You will find that there are many different ways that companies are able to recycle asphalt, and they are using the recycled materials to make the roads better by fixing ruts, cracks, potholes, and more. Some of the techniques currently used to reclaim asphalt include the following.
With Cold in Place Recycling, they cut several inches into the pavement and then crush the material. They introduce an additive, as well as an amount of virgin aggregate, to reclaim and reuse the asphalt and make it seem brand new. Hot in Place Recycling heats up the pavement, and new material is added to provide a new and better surface. Both of these techniques make use of recycling asphalt, and they are just two of the options that companies are using today.
Because of the savings benefits that these techniques and others can provide, more and more city and state governments are starting to use recycled asphalt. It makes sense for the taxpayers as well as the environment.
