Over the years, asphalt has become the most popular choice when it comes to selecting environmentally friendly pavements. To take it one step further, cold mix pavement layers have been developed to create even more sustainable products for road construction. Cold recycling techniques are methods that not only avoid the application of heat but reuse aged asphalt pavements already within the current infrastructure. This technique used helps treat raveling, potholes, skid resistance, rutting, block cracking, and so much more.
Cold recycling includes two subcategories, cold in place recycling (CIR) and cold central plant recycling (CCPR). In this article we will highlight a successful CIR project in Jefferson County, Indiana.
