Cold In-Place Recycling Using Solventless Emulsion – Phase IV (Emulsion Qualification and Long-Term Field Performance)

This report looks into how a successful Cold In-Place solventless emulsion behaves and how the emulsion break test developed in Phase III of this project demonstrates that behavior. Modifications to the test have been made to improve the consistency of the test. A modified laboratory procedure is proposed. The report also considers the factors contributing to successful field performance. Six Cold In-Place Recycled Asphalt Pavement (CIR) projects done over the last eight years were cored. These samples were subjected to Density, Stability and Fracture Energy determination. Results from these tests were compared to a Performance Index designed to normalize age, overlay condition and CIR condition. It was determined that, while poor performing projects exhibited similar stability to high performing projects, the poor performers exhibited low density and low fracture energy compared to the good performers.
