Special Issue Information

Dear Colleagues,

Since entering the 21st century, the emergence of new functional materials and the development of interdisciplinary research have provided strong support for the design and construction of all kinds of green roads. As a vital and integral component of transportation infrastructure, pavement has a direct and tangible impact on socio-economic sustainability. In recent years, an influx of groundbreaking and state-of-the-art materials, structures, and detection technologies related to road engineering have progressively emerged. Scholars around the world have carried out a great deal of in-depth research on pavement engineering and road materials, and a number of important innovative results have been achieved, which is of great significance for promoting road service performance.

This Special Issue addresses the above issues and aims to gather recent research work that advances knowledge about new pavement engineering and road materials. This Special Issue encourages the submission of academic, empirical, and case study research focusing on the topics below.

  • Green design and construction;
  • Applications of novel materials in pavement construction;
  • Polymer bonding materials;
  • Fiber-modified road materials;
  • Drainage pavement;
  • Cracking and healing in pavement;
  • Asphalt fume pollution prevention and control;
  • Automotive exhaust degradation materials;
  • Recycling for waste pavement materials;
  • Carbon footprint capture of road materials in the whole life cycle;
  • Biomass asphalt materials.

We look forward to receiving your contributions.

To promote the application of economical and sustainable polyphosphoric acid (PPA)-modified asphalt in road engineering, styrene-butadiene block copolymer (SBS), styrene-butadiene rubber (SBR), and PPA were used to prepare PPA/SBS and PPA/SBR composite-modified asphalts, which were tested and the data analyzed. Fourier transform infrared spectroscopy (FTIR) tests and thermogravimetric analysis (TG) tests were carried out to study the modification mechanisms of the composite-modified asphalts, and the high-temperature performance of the PPA-modified asphalt and asphalt mixtures was analyzed by dynamic shear rheology (DSR) tests and wheel tracking tests. A gray correlation analysis and a back-propagation (BP) neural network were utilized to construct a prediction model of the high-temperature performance of the asphalt and asphalt mixtures. The test results indicate that PPA chemically interacts with the base asphalt and physically integrates with SBS and SBR. The PPA-modified asphalt has a higher decomposition temperature than the base asphalt, indicating superior thermal stability. As the PPA dosage increases, the G*/sinδ value of the PPA-modified asphalt also increases. In particular, when 0.6% PPA is combined with 2% SBS/SBR, it surpasses the high-temperature performance achieved with 4% SBS/SBR, suggesting that PPA may be a good alternative for polymer modifiers. In addition, the creep recovery of PPA-modified asphalt is influenced by the stress level, and as the stress increases, the R-value decreases, resulting in reduced elastic deformation. Furthermore, the BP neural network model achieved a fit of 0.991 in predicting dynamic stability, with a mean percentage of relative error (MAPE) of 6.15% between measured and predicted values. This underscores the feasibility of using BP neural networks in predictive dynamic stability models. Full article
