Book Description
Vegetable-based oils such as corn and soybean oil have triglycerides and fatty acids that allow them to be considered sustainable and effective recycling agents (RAs) for aged asphalt binder. However, there are concerns about their effect on the recycled asphalt binder's long-term performance, moisture damage resistance, and self-healing characteristics restoration. In this study, crude corn oil (CO) and crude soybean oil (SO) were used as RAs to restore the performance of a reclaimed asphalt binder (RAB) extracted from reclaimed asphalt pavement. The binder extracted from RAB was modified with a neat binder PG64-28 and RAs to restore the high-end performance grade. To address concerns about the long-term performance of the RAs, the modified binders were further modified with either dilauryl thiodipropionate (DLTDP) or zinc diethyldithiocarbamate(ZnDEC) as antioxidants (AO) and rheological, chemical, and moisture susceptibility analyses were conducted. Adding ZnDEC improved the binder’s rheological efficacy at resisting long-term aging but reduced the binder’s moisture resistance while adding DLTDP did not improve efficacy and resulted in inferior binders. The binders modified with RA and AO were tested for damage susceptibility and self-healing (H%) using simplified viscoelastic continuum damage theory (S-VECD) to observe whether the addition of CO restored the self-healing properties of the binder. The use of CO improved the damage resistance and H%. Later, molecular models were prepared for the studied modified binders using molecular dynamics simulation to test the capability of CO to restore rheological properties, damage resistance, and H%. The simulation showed that CO improved the modified binder model's density, viscosity, glass transition temperature, and self-healing ability. The study recommends using natural bio-oils and organic antioxidants to improve the performance of recycled binders and exploring their usefulness and their relation to life-cycle analysis and cost analysis.

Book Description
This Tech Brief summarizes guidance to the pavement community on sustainability considerations for asphalt pavement systems, as presented in greater detail in the recently published Towards Sustainable Pavement Systems: A Reference Document (FHWA 2015b). Sustainability considerations throughout the entire pavement life cycle are examined (from material extraction and processing through the design, construction, use, maintenance/rehabilitation, and end-of-life phases) and the importance of recognizing context sensitivity and assessing trade-offs in developing sustainable solutions is emphasized. This Tech Brief focuses exclusively on sustainability considerations associated with asphalt-surfaced pavement structures and the materials used in their construction. For the purposes of this document, all permanent surfaces constructed with asphalt concrete are generically referred to as 'asphalt' pavements. The primary audience for this document is practitioners doing work within and for government transportation agencies, and it is intended for designers, maintenance, material and construction engineers, inspectors, and planners who are responsible for the design, construction and preservation of the nation's highway network.

Book Description
Shrink of nonrenewable natural resources and the pollution generated by many manufacturing industries have initiated a global determination for pushing the industry toward more sustainable products. Asphalt as the principal element of almost any street and highway pavement is integral in transportation development, which, in turn, is pivotal for sustainable development. On the other hand, the material consumption and pollution generated in the asphalt industry pose significant threats to the environment and, therefore, to sustainability. This chapter reflects some of the sustainability concerns of the asphalt industry and discusses some of the possible solutions to mitigate them. The sustainability considerations are categorized into four phases of asphalt life cycle namely: (1) extraction of materials, (2) processing of raw materials, (3) transportation of asphalt raw materials and products, and (4) reusing and recycling at the end of a pavement,Äôs life. In each phase, best practices to improve and maintain the sustainability of asphalt pavements are discussed. This chapter also discusses sustainable approaches and technologies in the asphalt industry such as warm mixes, permeable asphalt pavements as well as the potentials for improving the mechanical properties of asphalt pavements particularly in terms of resisting heavy load traffic, clogging, and freeze-thaw.

Book Description
"The topic addressed in the book is very wide, and it is commendable that such a wide range of subtopics are actually covered in enough depth to make it worthwhile to read.....The approach of not only providing technical pavement information, but also relevant applicable regulatory, policy, planning and environmental information provides a good background of the topic to pavement engineers - again information that most of them would not necessarily have had access to without such a compilation of information.....Overall, I view the book as an essential addition to the literature on sustainability in pavements and trust that it will contribute to improved understanding and application of more sustainable practices in highway engineering." - Prof. Wynand JvdM Steyn, Department of Civil Engineering, University of Pretoria, South Africa ************** The worldwide increase in emphasis on sustainability and the environment necessitates a holistic examination of how highways and pavements can be designed, constructed, operated, maintained, preserved and recycled in a more economically, environmentally, and socially sound manner. Rapidly depleting natural resources, anthropogenic climate change implications and increasing financial pressures are some crucial challenges today's and tomorrow's transportation engineers are faced with. A better understanding of the art and science of sustainable highway and pavement engineering will equip them to effect positive economic, environmental, and social change while balancing competing interests. Sustainable Highways, Pavements and Materials provides introductory and yet up-to-date coverage of latest technologies, practices and initiatives related to the contemporary application of sustainability principles during all phases of a pavement's life cycle. Researchers, practitioners, educators and students with an interest in transportation infrastructure will find this book a practical reference that explores various aspects of sustainable highways and pavements, including materials, design, construction, and life-cycle analysis. Important Topics Covered: -Sustainable Transportation Initiatives -Sustainability Impacts of Highways and Pavements -Environmental Life-Cycle Assessment (LCA) of Pavements -Recycled Materials and Beneficial Reuse of Industrial By-Products -Long-Life, Permeable, Quiet and Cool Pavements -Green Highway Rating Systems -Emerging Sustainable Pavement Materials and Technologies

Book Description
Since 2001, Texas has been designed and constructed 10 sections of perpetual pavement (PP) on heavily trafficked highways. With the oldest section having a service life of over 14 years, there is an opportunity to review the existing PP design and construction practices with a view of enhancing the design procedures and recommending the best construction practices for cost effectiveness. A critical review of field performance is warranted with recommendations on how to make these pavements cost competitive with both conventional 20 years flexible pavements and rigid concrete pavements.
