dc.description.abstract
This study evaluates the performance of plastic-modified bitumen using Multiple Stress Creep Recovery (MSCR) tests, analyzing non-recoverable creep compliance (Jnr) and recovery (R). Results demon-strate that 4.5% plastic-modified bitumen (B-4.5) exhibits optimal resistance to permanent deformation, with the lowest Jnr (0.18 kPa⁻¹) and highest R (68%) at ≥3.2 kPa stress, attributed to enhanced polymer network elasticity. Unmodified bitumen (B-0) showed a 113% Jnr increase beyond 6.4 kPa, linked to non-recoverable deformations at temperatures exceeding its PG grade (70°C vs. PG 64). Excessive plastic (>4.5%) increased stress sensitivity, with B-6/B-7.5 showing higher Jnr-slope due to polymer network breakdown under creep and recovery loading. Negative recovery at extreme stresses (≥6.4 kPa for modified; 0.1 kPa for unmodified) arose from rheometer limitations, accumulated strain, or bitumen flow. Findings advocate ≤4.5% plastic con-tent to optimize stress sensitivity and deformation resistance, enhancing pavement durability in high-temperature, high-stress environments.
