A study was conducted to characterize the behavior of cold recycled asphalt pavement (RAP) millings rejuvenated with high float emulsion and portland cement, producing a cement-emulsion mix. The main objectives were to investigate how the behavior of RAP mixes was affected by the addition of cement and to find the optimum emulsion and cement contents. Test samples were prepared with four different cement contents, three emulsion contents, and one free water content. It was concluded that Hveem stability values increased with cement content but decreased with emulsion content. The addition of portland cement affected the Hveem stability value of samples cured under soaked conditions more than those cured under dry conditions. Samples prepared with 2 percent emulsion had the highest gain in soaked stability because of the addition of cement. Overall it was concluded that a cold RAP mix containing a low percentage of cement would perform better than conventional cold RAP mixes.
