Abstract
In this paper, cement is used to stabilize reclaimed asphalt pavement materials (RAP) and original aggregate with the same gradation. Compressive strength, freezing-thawing resistance and fatigue life of cement recycled RAP mixture (CRAPM) and cement stabilize original aggregate mixture (CSAM) are evaluated. Test results indicate the compressive adhesive strength of cement-RAP is lower than cement-original aggregate. At the same gradation, RAP has negative effect on the freezing-thawing resistance of CRAPM, and can increase the fatigue life sensitive to stress level. Therefore, for using 100% RAP, it is necessary to increase the cement content to properly improve the strength and durability of RAPM in order to satisfy the specification of cement stabilized base materials in china.
