Evaluation of the mechanical behaviors of cement-stabilized cold recycled mixtures produced by vertical vibration compaction method
Cement-stabilized cold recycled mixtures (CCRMs) are widely used to rehabilitate and repair asphalt pavements. During laboratory production, the mechanical behaviors of these CCRMs are affected by the compaction method of the two types of compaction methods used in CCRM production, namely static pressing compaction method (SPCM) and vertical vibration compaction method (VVCM), and the latter has caught the attention of researchers owing to its advantages. However, current studies have only investigated the mechanical behaviors of CCRMs produced by SPCM but not through VVCM. The current research aimed to evaluate the mechanical behaviors of CCRM produced by VVCM. A total of 18 CCRMs were designed with different ratios of recycled cement base to recycled asphalt pavement, virgin aggregate contents and cement contents. The mechanical behaviors of CCRM produced by VVCM were evaluated, and the influencing factors were investigated. Scanning electron microscope was also used to analyze the strength formation mechanism of CCRM. The study results are useful for engineering practice, particularly for identifying the properties of CCRM produced by VVCM.
