Research on the mechanical properties of Cement recycled reclaimed asphalt pavement mixture
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.
