Mechanical Characterization of Asphalt Mixtures Based on Polymeric Resin and Thixotropic Filler as a Substitute for Bitumen

Transportation infrastructure relies heavily on asphalt pavement, but conventional bitumen-based mixtures present several drawbacks. This study assesses the potential of poly(methyl methacrylate) resins and thixotropic fillers as substitutes for bitumen to improve pavement performance. The research concentrates enhancing current formulations that incorporate a thermosetting polymer mineral (stiffening) fillers, with objective increasing durability, extending product life cycle, optimizing raw material usage. Utilizing dynamic thermomechanical analyses, viscoelastic characteristics are examined, focus their mechanical properties’ dependence load frequency temperature. investigation also evaluates impact different including silica sand, dust, basalt behavior load-bearing capacity, offering valuable insights into relationships between structure properties. findings reveal stiffness is predominantly affected by quantity whereas force plateau depends amount sand. contributes crucial information development more sustainable robust materials future applications.
