Study of the Aging Behavior of Asphalt Mastic: Impact of the Powder-to-Binder Ratio and the Aging Method
AbstractThis research conducted a comprehensive assessment of how aging processes and the powder to binder ratio (P/B ratio) influence asphalt mortar’s performance. Analysis demonstrated that all tested performance metrics significantly differed (P

Analysis demonstrated that all tested performance metrics significantly differed (P<0.05), signifying a notable effect of the aging process, particularly long-term thermal oxidation aging, on key properties such as ductility and the complex shear modulus (G*). Adjusting the P/B ratio enables precise control over the rate of aging and the asphalt mixture’s functional characteristics. The optimal P/B ratio, found to be between 0.8 and 1.0, effectively balances aging properties with mechanical strength.
