Laboratory Fatigue Performance of Vertical Vibration Compacted SRX-Stabilized Crushed Rock Material

摘要

The fatigue performance of Solution Road RomixSoilfix (SRX)-stabilized crushed rock material (SRX-CRM) has rarely been studied. This study investigated the fatigue performance of SRX-CRM obtained through vertical vibration compaction. The fatigue equations of SRX-CRM are established. In addition, the fatigue performances of SRX-CRM and cement-stabilized macadam (CSM) are compared. Results show that under a 50% failure probability, the regression coefficient a of the fatigue equations varies from 0.12 to 0.16, and the regression coefficient b varies from 0.0573 to 0.0507. The fatigue properties of SRX-CRM considerably increase from 0.50% to 0.75% with the SRX content, especially under high stress levels. The fatigue performance of SRX-CRM is evidently better than that of CSM.
