Special Issue Information

Dear Colleagues,

We are delighted to invite you to contribute to a Special Issue of the Journal of Sustainability, focused on "Asphalt Binder and Sustainable Pavement Design". As guest editors for this edition, our aim is to bring together the latest research and innovations in asphalt pavement engineering, with a strong emphasis on sustainable practices, advanced technologies, and environmental considerations.

Rationale for the Special Issue:

Transportation infrastructure, particularly asphalt pavement, plays a vital role in supporting economic growth and connectivity; however, it presents significant financial and environmental challenges. As construction and maintenance costs escalate, the demand for sustainable solutions to reduce environmental impact, optimize resources, and enhance pavement performance grows.

This Special Issue aims to address these challenges and highlight the pivotal role of asphalt binder in sustainable pavement design. We will focus on asphaltic materials, production methods, polymer modification, recycling agents, and technological advancements to create a comprehensive platform for knowledge exchange among researchers and practitioners.

Topics of Interest:

The Special Issue will explore innovative materials and techniques to enhance the sustainability of asphalt pavements. Topics of interest include recycled asphalt singles, rubber-modified asphalt, recycled-plastic asphalt, warm-mix asphalt, cold-mix asphalt, and other similar binders. Our aim is to promote cutting-edge research that reduces reliance on non-renewable resources, minimizes greenhouse gas emissions, and boosts the overall resilience of asphalt pavements.

Additionally, we will focus on sustainable pavement design practices that extend pavement service life, reduce maintenance costs, and minimize environmental impact. We encourage contributions exploring novel approaches to asphalt mix design, characterization, and evaluation, with an emphasis on high-performance materials and eco-friendly additives.

Call for Contributions:

We welcome original research papers, review articles, and technical notes addressing the following topics (but not limited to):

  1. Innovative asphalt mix design and characterization.
  2. High-performance asphalt materials and additives.
  3. Recycling and reuse of reclaimed asphalt pavement (RAP).
  4. Warm mix asphalt (WMA) technologies.
  5. Asphalt pavement preservation and maintenance strategies.
  6. Sustainable and eco-friendly asphalt pavement practices.
  7. Advances in asphalt pavement construction and rehabilitation techniques.
  8. Evaluation and monitoring of asphalt pavement performance.
  9. Life-cycle assessment and environmental impact analysis.
  10. Novel applications of asphalt pavements in specialized areas.
  11. Technological developments for improving asphalt pavement sustainability.
  12. Smart and connected infrastructure for intelligent asphalt pavements.

Join us in this endeavor:

We extend our heartfelt invitation to researchers, academicians, and professionals from diverse backgrounds to contribute their valuable work to this Special Issue. Through collaboration and knowledge exchange, we can drive the transformation of asphalt pavement engineering towards a more sustainable and environmentally conscious future.

The stabilization of asphalt pavement bases with granular soil and aggregates emulsified with asphalt is a widely used technique in road construction and maintenance. It aims to improve the mechanical properties and durability of the lower pavement layers. Currently, there is no consensus on the most suitable method for designing emulsified granular aggregates with reclaimed asphalt pavement (RAP), as it is very complex. Therefore, the methodology is generally based on compliance with one or more volumetric or mechanical parameters established in the highway regulations for conventional asphalt mixtures, which does not guarantee the optimization and characterization of the recycled mixture in the base course. In this study, granular mixtures were developed, including five with emulsion and one emulsion-free as a control mix. Granular RAP mixes were designed in this study, including five with emulsion and one emulsion-free as a control mix. The five mixes ranged from 1% to 5% emulsion and were characterized by multi-stage triaxial tests with repeated load resilient modulus (RM) and permanent deformation (PD) to evaluate their mechanical behavior. The results showed that the mixes had RM values between 350 and 500 MPa, consistent with literature values. However, they showed similar levels of accumulated deformation to the control mix without RAP emulsion. The sample with 1 % RAP emulsion exhibited a satisfactory RM value and better performance in PD than the control mix (5 mm) and showed accumulated PD values of up to 4 mm. In contrast, the other samples exhibited deformations of up to 6 mm. In this study, the multi-stagge triaxial RM and PD tests were found to be an effective predictive method for characterizing the behavior of RAP materials in base courses, regardless of the types of admixtures contained. Multi-stage resilient modulus and PD tests can be considered as a predictive method for the behavior of milled material in base courses. They were able to provide initial data for interpreting the behavior of ETB mixtures. Full article

Cold-mix asphalt is a greener alternative to pavement construction, processed at 10–40 °C, which is typically lower than other techniques like warm-mix asphalt and hot-mix asphalt. Huge amounts of construction and demolition waste, such as broken bricks, recycled concrete aggregates, reclaimed asphalt pavement, ceramic waste, etc., are generated every year due to the acceleration in infrastructure development. The production of such massive amounts causes landfilling issues, and their disposal is a serious issue nowadays. This study examines the effect of binary blended fillers on the performance of cold asphalt mixes using emulsified binders and 50% reclaimed asphalt pavement materials. Moreover, three types of binary blended fillers (BBFs), cement, fly ash, and Stabil Road, were used at different dosages. Overall, 500 samples were prepared for the mix design, and the optimum emulsion content was determined as 11% and 9% for the CM and 50R mixes, respectively, based on the Marshall stability peak value and volumetric properties such as voids in the mineral aggregates, total voids, and dry density. The moisture susceptibility of the recycled cold-mix asphalt (RCMA) mixture was evaluated using the tensile strength ratio. Cantabro abrasion loss was used to assess the cohesion resistance of the mixtures. The dynamic response of the mixes to the applied load was evaluated using the resilient modulus. The results of the present study reveal that using BBFs in the RCMA improved the inter-particle bonding and strength. Furthermore, BBF incorporation enhanced the performance of the recycled cold-mix asphalt. Full article

The crumb rubber (CR) recycled from waste tyres could be a viable alternative in achieving green pavements that offer exciting new markets to global investors. Adding CR into flexible pavements enhances their performance and ensures environmental sustainability. This paper will discuss the production variables, CR sizes and contents, blending techniques, optimum bitumen contents, morphology, standard characteristics, rheological characteristics, mechanical performance, greenhouse gas emissions, energy consumption and life cycle cost. This review study found that compared to traditional asphalt mixtures, the CR-modified asphalts had superior performance and longer service life. However, the dearth of information on several factors in CR asphalt production, including greenhouse gas emissions, energy consumption and life cycle cost during recycling, causes many agencies in the global asphalt industry to continue employing costly, energy-consuming additives such as styrene-butadiene-styrene (SBS) instead of CR to enhance asphalt.
