Special Issue Information

Dear Colleagues,

I am pleased to announce this Special Issue on "Rheology of Binders and Asphalt Mixtures" in the journal Applied Sciences. The rheological properties of binders and asphalt mixtures are crucial for understanding their performance, durability, and suitability in various climatic and loading conditions. This Special Issue aims to highlight recent advancements and innovative research in the rheology of binders and asphalt mixtures, providing a comprehensive platform for researchers, engineers, and industry professionals to share their findings, methodologies, and insights. By focusing on the rheological behavior, this Special Issue seeks to enhance the knowledge base and inform the development of better-performing and longer-lasting asphalt pavements.

The relevant topics for this Special Issue aims are as follows:

  1. Rheological characterization: advanced techniques for characterizing the rheological properties of asphalt binders and mixtures.
  2. Additives and modifiers: effects of various additives and modifiers on the rheological properties and performance of asphalt materials.
  3. Aging and durability: investigation of the aging processes and their impact on the rheological properties and durability of asphalt binders and mixtures.
  4. Recycling and sustainability: rheological performance of recycled materials and sustainable practices in asphalt production.
  5. Field performance correlations: linking rheological properties with field performance and pavement life.

The dynamic modulus (∣E*∣) is a fundamental mechanical parameter for studying the performance of hot mix asphalt and simulating its viscoelastic behaviour under different loading and thermal conditions. It is a primary tool to replicate road surface behaviour under vehicle traffic loading and temperature variations. Though, laboratory testing to determine this parameter is time-consuming and costly. Several predictive models have been developed to estimate the dynamic modulus, ranging from rheological to empirical regression models. This research was dedicated to studying two predictive models for determining the master curve of the dynamic modulus of hot mix asphalt used in a regular pavement binder course containing different reclaimed asphalt contents (0%, 30%, 40%, and 50%). Laboratory experiments were conducted to assess their accuracy. The results show that Witczak’s sigmoid function provided the best accuracy for the master curves, while the Generalized Huet-Sayegh (2S2P1D) model showed less accurate predictions, particularly at the range of low and high frequencies.
