Special Issue Information

Dear Colleagues,

In recent years, there has been a growing focus on pavement design and corresponding material performance evaluations due to increasing concerns over climate change and environmental degradation. Traditional road construction practices often result in high energy consumption, greenhouse gas emissions, and the depletion of natural resources. This has led researchers and engineers to explore alternative solutions that minimize the ecological footprint of pavement construction and maintenance.

To explore the breadth of pavement materials research, several topics are suggested for this Special Issue. First, research papers could address the development and characterization of pavement materials, molecular simulations, and microscopic characterization for bituminous materials' modification, such as recycled aggregates, reclaimed asphalt pavement (RAP), or bio-based binders. This topic aims to highlight the use of alternative materials that minimize the consumption of natural resources and reduce waste generation. Unconventional waste, such as E-waste, medical waste, agro-waste, industrial waste with alternative binders such as alkali-activated materials, and geopolymers in pavement applications, should be addressed.

Next, topics revolving around innovative construction and maintenance practices would be very beneficial. This would include research on novel pavement design methods, such as incorporating porous pavements for stormwater management or utilizing warm mix asphalt technologies for reduced energy consumption during construction. Additionally, we hope to receive studies addressing effective techniques for pavement recycling, rehabilitation, and maintenance to minimize environmental impacts.

In addition, studies focusing on the evaluation of sustainable pavement performance and durability would be valuable contributions. This research could investigate the long-term behavior of eco-friendly materials and techniques, considering factors like load conditions, severe environmental conditions, and overall structural integrity.

We invite you to share your latest research in this Special Issue of Materials. Both original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Activation mechanisms and characterization of modified asphalt properties.
  • Molecular simulations and microscopic characterization for bituminous materials' modification.
  • Multiscale mechanics and Multiphysics modeling for pavement structure and materials.
  • Mechanical response and failure mechanism of the adhesive layer of asphalt pavement.
  • Intelligent transportation of infrastructural materials and technologies.
  • Simulation of pavement structures and materials.

We look forward to receiving your contributions.

Electrified pavements with inductive charging systems provide an innovative way of providing continuous wireless power transfer to electric vehicles (EVs). Electrified pavements have unique construction methods, resulting in different mechanical and thermodynamic characteristics from traditional pavements. This study aimed to investigate the mechanistic design of electrified pavements to mitigate thermal-induced reflective cracking due to the inclusion of concrete slabs with inductive charging units (CUs) under an asphalt surface layer. Finite element (FE) models were developed to analyze the temperature profiles, pavement responses, and crack potential in electrified pavements. The fatigue model and Paris’ law were utilized to evaluate crack initiation and propagation for different pavement designs. Within the allowable range for sufficient wireless charging efficiency, increasing the surface layer thickness had a noticeable benefit on mitigating crack initiation and propagation. The results indicate that increasing the asphalt surface layer thickness by 20 mm can delay crack initiation and propagation, resulting in a two to threefold increase in the number of cycles needed to reach the same crack length. Reflective cracking can also be retarded by the optimized design of the charging unit. Increasing the concrete slab thickness from 100 mm to 180 mm resulted in an approximately 20% increase in the number of cycles to reach the same crack length. Reducing the slab width and length (shortening joint spacing) could also effectively reduce the reflective cracking potential, with the slab length having a more significant influence. These findings highlight the importance of balancing charging efficiency and structural durability in the design of electrified pavements. Full article

Generally, rejuvenators are used to supply missing components of aged asphalt, reverse the aging process, and are widely used in asphalt maintenance and recycling. However, compared with traditional rejuvenators, bio-oil rejuvenators are environmentally friendly, economical and efficient. This study looks into the effect of the three different bio-oils, namely sunflower oil, soybean oil, and palm oil, on the physical properties, rheological properties and chemical components of aged asphalt at different dosages. The asphalt physical properties and Dynamic Shear Rheological (DSR) test results show that with the increase in bio-oil, the physical properties and rheological properties of rejuvenated asphalt are close to those of virgin asphalt, but the high-temperature rutting resistance needs to be further improved. The results of Fourier Transform Infrared Spectroscopy (FTIR) show that the carbonyl and sulfoxide indices of rejuvenated asphalt are much lower than those of aged asphalt. Moreover, the rejuvenation efficiency of aged asphalt mixed with sunflower oil is better than that with soybean oil and palm oil at the same dosage. Full article
