Abstract
A rational rehabilitation design should be based on the understanding and knowledge of the existing pavement distress or condition. The purpose of this research was to investigate the effects of reclaimed asphalt pavement (RAP) content and cement content on the strength of full-depth reclamation (FDR) base. FDR for asphalt pavement with cement as the stabilizer was used as the base course. The full-factorial experimental design included five RAP contents and five cement contents. To ensure the reproducibility, there were three replicates for each specimen. The 7 days; unconfined compressive strength (UCS) was used as the control parameter. The five RAP contents consisted of 0%, 25%, 50%, 75%, and 100%. The five cement blending contents included 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%. The test results indicate that the optimum design was 50% RAP and 2% cement.
