As with many other industries, construction companies are using recycled asphalt not only for cost-effective measures but also to improve the condition of the roads.
There are many benefits to using recycled asphalt. Recycling asphalt helps the environment because fewer materials are needed. It also reduces the amount of discarded asphalt that ends up in landfills. Conversely, new asphalt requires the use of sand, stone, and oil, and without this need, there is the potential to reduce contributions to greenhouse gases.
Outside of the recycled material’s environmental benefits, there are cost-savings advantages and benefits to the road itself. Fewer production of new asphalt means reduced purchase costs of raw materials. In 2015, it is estimated that companies in the United States saved close to two million dollars on recycled asphalt. However, recycled asphalt is just as good as new asphalt because, by mixing old asphalt with new asphalt, there is the potential to create stronger mixes. Moreover, the aggregate (new material and old asphalt) reduces cracking and rutting on the road.
