Tóm tắt
The incorporation of reclaimed asphalt pavement (RAP) into warm mix stone matrix asphalt (WSMA) has attracted increasing attention due to its potential to reduce natural resource consumption, energy demand, and environmental impacts associated with asphalt pavement construction. However, the use of RAP in SMA mixtures may significantly influence the balance between rutting resistance and cracking performance because of the stiffening effect of aged binder. Therefore, this study investigates the influence of RAP content on the mechanical performance of WSMA mixtures. Four mixtures containing 0%, 10%, 20%, and 30% RAP were designed using a warm mix additive, a bio-based rejuvenator, and cellulose fiber. The performance of the mixtures was evaluated through IDEAL-RT and IDEAL-CT tests to characterize rutting and cracking resistance, respectively. The results indicated that increasing RAP content significantly improved rutting resistance, as reflected by higher shear strength and RTIndex values. However, the cracking resistance gradually decreased with increasing RAP content due to the increased stiffness and brittleness of the aged binder system. Among the investigated mixtures, the WSMA containing 20% RAP exhibited the most balanced mechanical performance, providing substantial rutting improvement while maintaining acceptable cracking resistance.Tài liệu tham khảo
