“…Therefore, it is necessary to point out that asphalt mixtures are usually composed of aggregates, fillers, binders, and sometimes additives. Approximately 85% to 95% of the mix is composed of aggregate and fillers, the rest is filled by asphalt [9,10,12].…”

The need to meet society's demands for road infrastructure while minimizing the resulting environmental impacts is a source of great complications. In this context, Life Cycle Assessment (LCA) can be useful by applying a set of rules and processes for the environmental assessment of projects. The objectives of this study were to present the main environmental impact categories associated with emissions from the life cycle phases of a road pavement and how to estimate them. In addition, this paper provides examples of LCA applications on these infrastructures. In view of the evolution of research on LCA, a compilation was made on: the main categories of environmental impact associated with emissions; phases of life cycle impact assessment; and procedures and methods of impact estimation. The impact categories presented are associated with climate change, acidification, ozone depletion, tropospheric ozone formation, eutrophication, and Particulate Matter Formation. Not all methods are able to generate indicators for all types of impact and, depending on the type of materials and services that make up the inventory of the alternatives analyzed, one specific method may be more appropriate to use. The conclusions are that for each environmental impact, the results depend on the input parameters, such as energy flows and materials, along with their processing by methods of life cycle impact assessment. Besides this, despite the great diversity of the databases for the steps of life cycle assessment of roadway pavement, there is a general consensus about the nature of these steps.

“…Bitumen binder containing up to 30% castor oil was also studied, showing a variety of positive effects with different properties [ 12 ]. Systematic studies on opportunities for the use of biobinders using different bio-oils derived from pyrolysis of different lignocellulosic biomasses was undertaken [ 13 ]. Generally, these types of bio-binder can improve the high-temperature performance of matrix asphalt, whereas the low-temperature performance of matrix asphalt would be slightly reduced [ 13 , 14 ].…”

Furanic Humins from Biorefinery as Biobased Binder for Bitumen

et al. 2022

To decrease the environmental impact of bitumen, more sustainable binders should be proposed. This study emphasizes how industrial humins co-produced during the biorefining of carbohydrates can be employed as a macromolecular binder for bitumen. Humins are heterogeneous polyfuranic compounds, and they were mixed at 50 wt% with bitumen. When the non-water-soluble fractions of humins were employed (Hns), no variation of the chemical structure was observed in FTIR spectra after the mixing. The DSC investigations showed that the crystallization of aromatic fractions in bitumen shifted to higher temperature for humins’ modified bitumen. The thermogravimetric data highlighted that the presence of humins or Hns in bitumen can lead to mass loss below 200 °C. The rheological investigations highlighted some key advantages of using humins or Hns with bitumen. At high temperatures, the storage modulus of the modified bitumen is increased and shows lower susceptibility to variations in frequency. At low temperatures, the phase angle of Hns-modified bitumen is lower than that of bitumen, suggesting less temperature susceptibility as a consequence of a cross-linked network formation.

“…Nevertheless, the rutting performance could be negatively affected by the incorporation of the bio-oils . On the other side, He et al (2019) also assessed and compared three different biomass sources (pine wood, willow wood and poplar wood) by means of their chemical composition. The authors found that the addition of the bio-binders to the neat asphalt can improve its high-temperature performance anti-rutting ability, whereas its low temperature anti-cracking ability is slightly harmed.…”
