Special Issue Information

Dear Colleagues,

The continuous evolution of pavement engineering has led to the development of innovative materials and technologies aimed at improving asphalt and concrete coating performance. The demand for longer-lasting, more resilient pavements has driven research into various modification strategies, including polymers, waxes, and chemical additives, to enhance durability, aging resistance, and mechanical properties. At the same time, sustainability has become a key focus, prompting efforts to optimize high reclaimed asphalt pavement (RAP) mixtures through careful gradation design, strategic application of recycling agents, and advanced characterization techniques. Additionally, technologies such as emulsified asphalt and warm-mix additives have emerged to enhance workability, lower paving temperatures, and reduce mixture viscosity, promoting energy efficiency and environmental benefits.

We are pleased to invite you to contribute to our Special Issue, which focuses on advancing sustainable and high-performance pavement materials and technologies.

This Special Issue aims to showcase recent advancements in pavement material innovations, performance evaluation methodologies, and predictive modeling techniques. We welcome original research articles and reviews that address various aspects of pavement engineering, including, but not limited to, the following:

  • Asphalt and concrete modification strategies;
  • Sustainable pavement materials and recycling techniques;
  • Advanced performance testing and characterization methods;
  • Workability and compaction improvements in asphalt mixtures;
  • Theoretical modeling approaches, including continuum damage and fracture mechanics;
  • Long-term field monitoring and service life prediction.

We look forward to receiving your contributions and sharing the latest research that will drive the future of pavement engineering.

Rubber powder asphalt has been widely studied due to its favorable temperature sensitivity and fatigue resistance. However, because rubber powder does not easily swell in asphalt, it leads to poor storage stability and high viscosity, limiting its large-scale application. In this study, modified asphalt was prepared using desulfurized rubber powder (DRP) and styrene-butadiene-styrene (SBS) modifiers, aiming to identify the optimal formulation for enhanced performance. It was hypothesized that the combined use of DRP and SBS would produce synergistic effects, improving the overall mechanical and rheological properties of the asphalt. To test this, the effects of this composite modification were evaluated using Marshall tests (penetration, softening point, ductility, elastic recovery, and Brookfield viscosity) and Superpave tests (shear modulus, high-performance grade, rutting factor, fatigue factor, and creep and recovery). Additionally, moisture susceptibility, high-temperature stability, low-temperature cracking resistance, and fatigue resistance at the mixture level were assessed. Performance was evaluated according to the Chinese standard JT/T 798-2019 for rubberized asphalt using reclaimed tire rubber. Results show that DRP-modified asphalt demonstrates excellent temperature sensitivity, rutting resistance, deformation resistance, and fatigue performance. However, an excessive amount of DRP increases Brookfield viscosity, which negatively affects the workability of the asphalt binder. The addition of SBS further improves the softening point, ductility, and deformation recovery of the binder. Considering cost-effectiveness and overall performance, the optimal formulation was determined to be 25% DRP and 1% SBS. At this dosage, all performance indicators met the required standards. The rotational viscosity at 180 °C was approximately 35% lower than that of conventional rubber powder–modified asphalt, while the high-temperature rutting factor and fatigue resistance at medium-to-low temperatures outperformed those of SBS-modified asphalt. The mixture test results reveal that the gradation has an impact on the performance of the obtained mixture, but overall, the DRP-SBS composite-modified asphalt mixture has significant advantages in terms of performance and cost-effectiveness.
