Effect of Fractured Aggregate Particles on Linear Stress Ratio of Aggregate and Resilience Properties of Asphalt Mixes—A Way Forward for Sustainable Pavements

The interlocking and packing of aggregate particles play a key role in achieving high level linear viscoelastic properties rutting resistance asphalt mix for sustainable pavements. In this study, the quantitative effect fractured (FAPs) on loading (i.e., 500 kPa normal stress), along with resilience mixes, was evaluated. Linear nonlinear stress behaviors aggregates (from direct shear test) mixes resilient modulus were analyzed. A new parameter (linear ratio), i.e., (Pi)/maximum (Pmax), is proposed to be used selection mixes. It observed that 15.5% increase FAPs caused 19.5% ϕ 70.7% ratio (LSR). same content resulted 29.4% 36% increases total (MRT) 34.2% 24.5% instantaneous (MRI) 0.1 0.3 s load durations, respectively.
