Laboratory Evaluation And Field Demonstration Of Cold In-Place Recycling Asphalt Mixture In Michigan Low-Volume Road, Dongzhao Jin, Lei Yin, Lance Malburg, Zhanping You

Michigan Tech Publications, Part 2

Cold-in place recycling (CIR) is a promising technology for the rehabilitation of asphalt pavements. However, the CIR asphalt pavement constructed in the field often has high air voids due to the presence of moisture during construction, and the moisture susceptibility of the pavement is crucial in determining its service life. Therefore, the objective of this research was to assess the laboratory performance of CIR asphalt mixes under freeze-thaw conditions (The mix prior to being subjected to freezing and thawing is labeled as "dry condition", while the mix that was placed in a refrigerator at –18 °C for 16 h and …
