| Abstract: | The accumulation of permanent deformation in unbound granular layers is a major contributor to rutting in flexible pavement systems. Adequate compaction of these layers is essential to mitigate rutting and ensure long-term performance. Although the importance of achieving compaction near the maximum dry density is widely recognized, the precise influence of the degree of compaction (DOC) remains insufficiently understood. This study presents a laboratory investigation on permanent deformation using cyclic triaxial testing of granular base materials composed of a 50/50 blend of virgin aggregates and recycled asphalt pavement. An analysis framework was developed to extract deformation model parameters based on the angular characteristics of strain accumulation relative to the number of load cycles at selected reference points. This method enables quantification of the combined effects of stress conditions and DOC on the rutting behavior of unbound recycled granular materials. [ABSTRACT FROM AUTHOR] |
