PDF Review of Cold In-Place Recycled Asphalt Concrete Projects

research focused on methods to recover asphalt from existing roads by recycling. Cold in-place asphalt recycling (CIR) is one of the recycling methods that was developed. It involves milling and crushing the existing asphalt pavement, rejuvenating the existing asphalt cement, and finally placing and compacting the material to a specified thickness.

Characterization of Recycled Aged CRM Binders" by Soon

The incorporation of conventional reclaimed asphalt pavement (RAP) in hot-mix asphalt (HMA) pavements has become routine in many states around the United States and many other countries all over the world. In addition, the recycling of crumb rubber modified (CRM) materials has been an area of interest since CRM was first used in asphalt paving materials over 40 years ago.
