Abstract Achieving lower temperature modification of SBS modified asphalt is vital significance in energy conservation and carbon emission reduction. The compatibility between styrene-butadiene-styrene (SBS) base a crucial factor for the excellent performance (SBSMA), however improvement under faces challenges its mechanism has little scientific backing. In this study, was firstly pretreated with naphthenic oil as swelling agent petroleum ether extractant to prepare pre-swelling (npSBS), effects pre-swelling/extraction process combined C9 resin on conventional properties, compatibility, rheological thermodynamic properties SBSMA prepared at shear (150 ℃) were studied by physical storage stability, DSR, MSCR DSC characterization. results demonstrated that treatment improved low well while reduced high performance. However, could effectively compensate loss rutting resistance comprehensive npSBS incorporating 6 wt% 150℃ comparative 180 ℃. synergistic effect improving temperature. This work provides feasible strategy environmentally benign low-carbon SBSMA.

The integration of reclaimed asphalt pavement (RAP) in road construction offers substantial environmental and economic benefits, yet the performance degradation recycled mixtures due to binder aging remains a critical challenge. This study addresses this issue by proposing novel filler-to-asphalt (F/A) ratio optimization strategy for mastic containing 50% aged binder. Recycled mastics with F/A ratios spanning 0.0 (pure control) 1.5 were evaluated using dynamic shear rheometer (DSR) bending beam (BBR) assess rutting resistance, fatigue life, low-temperature cracking performance. Results demonstrate that mineral filler amplifies stiffening effects binder, improving high-temperature stability but exacerbating brittleness. Fatigue exhibited method-dependent behavior, time sweep tests indicating extended life factor analysis revealing accelerated damage accumulation. Additionally, strong exponential or linear relationships established between indicators ratio. Based on these relationships, an adjustment value 0.3 0.5 was identified achieve comparable virgin mastic. These findings provide viable approach optimizing mix design RAP.

Amid the growing demand for sustainable pavement solutions and need to incorporate recycled materials into construction practices, this study explored viability of using crushed thermal power plant bottom ash as a filler in polymer-modified asphalt concrete mixtures. Conventional lime was replaced with at varying levels (0%, 25%, 50%, 75%), resulting mixtures were evaluated several performance tests. The optimal replacement level determined be based on results indirect tensile strength (ITS) test. Comparisons between control mixture 25% ash-modified conducted dynamic modulus test, Cantabro Hamburg wheel tracking (HWT) ratio (TSR) findings indicate that demonstrated improved across multiple parameters. HWT test showed enhanced rut durability, recorded depth 7.56 mm compared 8.9 mixture. revealed lower weight loss percentages modified mixture, indicating better abrasion resistance. indicated higher resilience stiffness both high- low-frequency stages. TSR highlighted moisture resistance, values after 10 wet-drying cycles. These improvements are attributed fine particle size beneficial chemical composition ash, which enhance mixture’s density, binder-aggregate adhesion, overall durability. suggest incorporating is viable approach improving longevity.
